Monstera deliciosa is one of the most rewarding houseplants you can grow, but getting the care right makes all the difference between a plant that merely survives and one that produces the large, glossy, fenestrated leaves it is famous for.
This guide covers everything you need to know: watering, light, soil, temperature, humidity, fertilising, repotting, pruning, training and support, propagation, pest control, common problems, leaf care, and where to position your plant.
Whether you have just brought your first monstera home or you have been growing one for years and want to improve your results, you will find clear and practical answers here.
Monstera Care at a Glance
Use this table as a quick reference before reading the full detail on each topic below.
| Care Factor | What Your Monstera Needs |
|---|---|
| Light | Bright, indirect light for 4 to 6 hours daily. No direct midday sun. Tolerates lower light but will not fenestrate well. |
| Watering | Water when the top 2 inches of soil feel dry. Water thoroughly until it runs from the drainage holes, then let it drain fully. |
| Soil | Chunky, free-draining aroid mix: roughly 1 part perlite, 1 part coco coir or peat moss, 4 parts pine bark fines. |
| Temperature | 18 to 30°C (65 to 86°F). Ideal range 20 to 30°C. Avoid anything below 12°C (54°F) and cold draughts. |
| Humidity | 60 to 80% is ideal. Tolerates down to 40%. Below 40% causes crisping and slowed growth. |
| Fertiliser | Balanced liquid feed at half strength, every 2 to 4 weeks during spring and summer. Stop in autumn and winter. |
| Repotting | Every 1 to 2 years in spring, moving up one pot size (1 to 2 inches wider) at a time. |
| Pruning | Spring or early summer; cut just below a node with sterilised tools to control size and shape. |
| Support | Provide a moss pole, coir totem, or trellis to encourage upward climbing growth and larger, more fenestrated leaves. |
| Growth Rate | Roughly one new leaf every 4 to 6 weeks in active growth (spring/summer); much slower in autumn/winter. |
| Toxicity | All parts contain calcium oxalate crystals. Toxic to cats, dogs, and humans if chewed or ingested. Sap irritates skin. |
What Is a Monstera?
The Monstera is a climbing evergreen plant native to the tropical rainforests of Central America, where it scales trees and other structures using thick aerial roots that anchor it as it grows toward the light filtering through the forest canopy.
In the wild it can climb several metres up a host tree, and it is this canopy-climbing habit that explains almost everything about how to care for it indoors.
Because it is adapted to warmth, high humidity, filtered light, and a loose, free-draining growing medium, replicating those conditions as closely as possible indoors is the key to a thriving plant.
In its natural range the Monstera grows in hardiness zones 10 to 12, so most homes will need to recreate a warm, humid, brightly lit but shaded micro-climate rather than relying on outdoor conditions.
The glossy, deep green leaves develop their characteristic splits and holes, known as fenestrations, once the plant matures and has consistent access to light and nutrients.
A young Monstera produces solid, heart-shaped leaves; fenestrations typically begin to appear once the plant is two to three years old and receiving good light.
There are many Monstera varieties, including variegated forms, but Monstera deliciosa is the most widely grown and is the focus of this guide.
A Note on Toxicity
Monstera is toxic to cats, dogs, and humans. All parts of the plant contain microscopic calcium oxalate crystals, which cause irritation, swelling, and a burning sensation in the mouth, throat, and digestive tract if chewed or swallowed.
Symptoms in pets typically include drooling, vomiting, and difficulty swallowing. The sap can also irritate skin and eyes on contact.
Keep the plant, any fallen leaves, and pruned cuttings out of reach of pets and young children. Wear gloves when pruning, propagating, or otherwise handling cut stems and sap, and wash your hands afterwards.
If a child or pet ingests any part of the plant, contact a doctor, NHS 111, or a veterinarian for advice.
How to Water a Monstera
Watering is the single factor that most affects Monstera health, and getting it right comes down to one principle: water when the soil needs it, not on a fixed schedule.
Monsteras are aroids that need a steady supply of moisture to produce their large, glossy leaves, but they are highly intolerant of sitting in waterlogged soil.
How to Check If Your Monstera Needs Water
Before you water, check the soil using one of these methods:
- The finger test: Push your finger into the soil to a depth of about two inches. If it feels moist at that depth, the plant does not need water yet. If it feels dry, it is time to water.
- The stick test: Push a wooden stick or skewer into the soil to the same depth, then pull it out. If it comes out clean and dry, the soil needs water. If soil clings to it, there is still enough moisture.
- A moisture meter: Insert a moisture probe into the soil for an instant reading. A reading around 1 to 3 generally indicates dry soil that needs watering, while readings of 7 to 10 indicate the soil is still wet. Aim to water when the reading drops to around 3.
How Much Water to Give
When you do water, water thoroughly. Apply a slow, steady stream to the soil itself (not over the leaves) until water runs freely from the drainage holes at the base of the pot.
This flushes the whole root zone evenly and helps prevent salt build-up from fertiliser.
Once it has finished draining, empty any water that collects in the saucer or drainage tray, since a Monstera left standing in water is at high risk of root rot.
There is no need to soak the pot for an extended period, as some growers do with very dry plants. A single thorough watering followed by full drainage is sufficient for a healthy Monstera.
If the plant has dried out severely and the soil has pulled away from the pot edges, you may need to water more slowly in stages so the dry mix has time to reabsorb moisture rather than letting water channel straight through and out.
How Often to Water
There is no single watering schedule that works for every Monstera. How quickly the soil dries out depends on the size of the pot relative to the plant, the potting mix, the season, light levels, humidity, and airflow.
As a general guide, most Monsteras need watering roughly once every one to two weeks during spring and summer, and once every two to four weeks in autumn and winter when growth slows.
Always let the condition of the soil guide you rather than the calendar.
Factors That Affect Watering Frequency
- Season: More water is needed during active growth in spring and summer; far less during the dormant winter months.
- Soil: Chunky, well-draining mixes dry out faster and may need slightly more frequent watering than dense mixes, though they are much safer against root rot.
- Pot material: Porous terracotta pots lose moisture to the air and dry out faster than glazed ceramic or plastic pots.
- Airflow: Plants near fans, vents, or draughty windows dry out more quickly and may need extra attention.
- Humidity: Higher ambient humidity slows evaporation from the soil, so the plant will need watering less often.
- Light levels: A plant in brighter light photosynthesises and transpires more, drawing up water faster and drying the soil sooner.
Signs of Overwatering
Too much water, or water that cannot drain away properly, is one of the most common causes of Monstera decline. Watch out for:
- Yellowing leaves, particularly on lower and older growth
- Dark, soft brown spots on the leaves
- Soggy or mushy stems at the base of the plant
- Mould or a white crust on the surface of the soil
- A sour or rotten smell coming from the pot, which indicates root rot has set in
If you suspect root rot, remove the plant from its pot, trim away any dark, mushy, or foul-smelling roots with a sterilised tool, and repot into fresh, dry potting mix.
Hold off watering for several days afterwards to let the remaining roots recover.
Signs of Underwatering
A Monstera that is too dry shows a different set of symptoms:
- Drooping or wilting leaves that do not recover shortly after watering
- Yellowing accompanied by dry, crispy brown edges or tips
- Soil pulling away from the edges of the pot, or cracking on the surface
- Very slow or stalled new growth
As a general rule, it is safer to slightly underwater a Monstera than to overwater it.
A drooping, dehydrated plant usually recovers quickly once watered, whereas a plant suffering from root rot is much harder to save.
When in doubt, wait an extra day and check the soil again before adding more water.
If your plant has gone beyond simple drooping, our guide on reviving a dying Monstera covers the recovery process step by step.
Guttation: A Normal Process to Expect
You may occasionally notice small droplets of water forming on the edges or tips of Monstera leaves, especially after watering or overnight.
This is called guttation, a natural process where the plant releases excess water and dissolved minerals through small pores.
It is harmless and does not indicate a problem, though if it happens very frequently it can be a sign the plant is being watered more than it currently needs.
How Much Light Does a Monstera Need?
In the wild, Monstera deliciosa grows beneath a dense forest canopy, which means it is adapted to bright but filtered light rather than direct, unobstructed sun.
Indoors, it performs best with bright, indirect light for roughly four to six hours each day.
Watering and light needs are closely linked: a plant in brighter light uses water faster and will need watering more often, while a plant in low light will use water much more slowly and is at greater risk of staying too wet for too long.
Direct Bright Light
Although many houseplants enjoy direct sun, the Monstera does not. In its natural habitat it receives only filtered light through other foliage.
If placed in direct, unobstructed sunlight, especially through a south-facing window in summer, the leaves can scorch, developing pale or brown patches that eventually turn crisp and may drop.
If your plant has already suffered sun damage, trim away the worst-affected leaf tissue and move the plant to a spot with filtered or indirect light to allow new growth to recover undamaged.
Indirect Bright Light
This is the ideal light level for a Monstera, as it most closely replicates the dappled light received under a forest canopy.
A simple way to check whether a position offers indirect light is to look at the shadow the plant casts: a soft, diffuse shadow indicates indirect light, while a sharp, well-defined shadow means the leaves are receiving direct sun and may be at risk of scorching.
Good positions include a few feet back from a south- or west-facing window, directly in front of an east-facing window (which receives gentler morning sun), or near a north-facing window in a bright room.
If a plant near a sunny window is casting a sharp shadow, either move it further back or use a sheer curtain to diffuse the light.
Low Light
A Monstera can survive in lower light conditions, but it will grow more slowly, produce smaller leaves, and is unlikely to develop fenestrations.
If your home does not receive much natural light, you can supplement with LED grow lights designed for houseplants, positioned 12 to 24 inches above the foliage and run for around 10 to 12 hours a day.
Placing mirrors near the plant to reflect available daylight can also help, though this is a smaller effect than a dedicated grow light.
Signs Your Monstera Is Not Getting Enough Light
- Lack of fenestrations: A plant that is at least two to three years old and otherwise healthy but still has solid, unsplit leaves may simply not be receiving enough bright light to trigger fenestration.
- Wet soil for an unusually long time: If the soil stays damp for far longer than expected between waterings, the plant may not be using water quickly enough because it is not receiving enough light to drive active growth.
- Discoloured leaves: New growth that emerges pale, washed-out, or yellowish (rather than deep green) often points to insufficient light, though this can also be a symptom of watering or nutrient issues, so check those factors too.
- Stunted or very slow growth: If growth has clearly slowed during what should be the active growing season, low light is one of the most common underlying causes.
- Leggy growth: Long stems with widely spaced leaves and little foliage in between (known as legginess) usually mean the plant is stretching toward a light source it cannot quite reach. Moving it closer to a bright window, or adding a grow light, will encourage more compact, leafy growth.
The overall goal is balance: avoid placing a Monstera in deep shade where it will fade and stretch, but also avoid the full glare of direct midday sun, which will scorch the foliage.
A bright spot with filtered or indirect light for several hours a day suits the plant best.
Taking a Monstera Outdoors
In the UK, a Monstera can spend time outdoors during the warmer months, but it must be kept in a sheltered, shaded spot, such as under a patio cover or in the dappled shade of a tree, as direct outdoor sun is far more intense than indoor light and will scorch the leaves quickly.
Bring the plant back inside well before night-time temperatures start to drop in autumn, since the Monstera has very little tolerance for cold.
What Soil Does a Monstera Need?
The right potting mix is one of the most important factors in keeping a Monstera healthy, because it directly affects how much water the roots receive, how well they can breathe, and how easily excess water can drain away.
A good potting mix provides several things at once: a stable medium for the roots to anchor in, good gas exchange so the roots can access oxygen, enough water retention to support the plant between waterings, free drainage so excess water moves through rather than pooling, a supply of nutrients, and a buffer against rapid temperature swings around the root zone.
A standard multipurpose compost on its own is usually too dense and water-retentive for a Monstera.
It compacts over time, holds too much moisture around the roots, and increases the risk of root rot.
Instead, use a chunky, open aroid mix that allows excess water to drain quickly while still holding enough moisture for the roots to use.
Characteristics of a Good Potting Mix
- Slightly acidic pH: A pH between 5.5 and 6.5 suits most aroids, including the Monstera.
- Coco coir: Made from coconut husks, it has a coarse texture that improves aeration while still holding some moisture.
- Sphagnum peat moss: Its fine fibres hold onto water and nutrients while still allowing air to reach the roots; it can be used as an alternative or addition to coco coir.
- Perlite: These lightweight, porous white granules create air pockets in the mix, improving both drainage and aeration.
- Pine bark fines: Chunky bark pieces resist compaction over time, keeping the mix open and well-aerated for longer than soil alone.
- Horticultural charcoal (optional): Some growers add a small amount of charcoal, which can help absorb impurities and keep the mix smelling fresh.
How to Make a Monstera Potting Mix
A simple and effective DIY mix uses the following ratio:
- 1 part perlite, for drainage and aeration
- 1 part coco coir or sphagnum peat moss, for moisture retention
- 4 parts pine bark fines, for structure, aeration, and resistance to compaction
Combine these thoroughly and use the mixture as the growing medium in any pot with adequate drainage holes.
The finished mix should feel light, gritty, and open when you handle it, not dense or claggy.
If you would rather not mix your own, a good-quality, ready-made aroid or houseplant mix from a garden centre is a reliable alternative, ideally one that lists bark, perlite, and coir among its ingredients.
Signs Your Potting Mix Is Wrong for Your Monstera
- Yellowing leaves despite correct watering: This often points to poor aeration or drainage in the mix, meaning the roots are not getting enough oxygen even when watering itself is appropriate.
- Brown spots that spread across the leaves: This can indicate that the mix is staying waterlogged for too long after watering, gradually causing root damage that shows up in the foliage.
- Water sitting on the soil surface: If water pools on top rather than soaking in and draining through within a reasonable time, the mix has likely become too dense or compacted.
- Roots visibly circling at the surface: This suggests the mix has compacted and the roots are struggling to penetrate it, often a sign that it is time to refresh the mix or repot.
Even with infrequent watering, a poor-quality mix that does not drain well can still lead to root rot, because water that cannot escape will sit around the roots regardless of how often you add more.
If you suspect the mix is the problem, the most reliable fix is to repot into a fresh, well-draining aroid mix as described above.
What Temperature Does a Monstera Need?
As a tropical plant, the Monstera performs best in temperatures between roughly 18 and 30°C (65 to 86°F), with an ideal range of about 20 to 30°C (68 to 86°F).
These conditions broadly match normal household temperatures in the UK during the warmer months, which is one of the reasons the Monstera does so well as an indoor plant here.
When temperatures fall below around 12°C (54°F), the plant begins to experience cold stress: growth slows noticeably and the plant may look less vigorous.
If temperatures drop to 10°C (50°F) and below, the risk increases significantly, with leaves potentially blackening or developing yellow patches.
Prolonged exposure to cold, particularly anything approaching freezing, can kill the plant outright.
Because of this, regulating temperature and avoiding cold exposure is non-negotiable for healthy growth.
Signs Your Home Is Too Cold for the Monstera
- Growth has stopped entirely, suggesting the plant has gone into shock from cold exposure
- Leaves turning black or yellow, particularly on the parts of the plant nearest a cold window or draught
- General wilting that does not correct itself after watering
- A loose, less anchored root ball when the plant is gently tested
- Drooping leaves that feel cool or limp to the touch
If you notice these signs, move the plant away from the cold source immediately, to the warmest consistently heated room in the home, and away from exterior walls, single-glazed windows, and draughty doors.
For a full seasonal routine, see our guide to caring for your Monstera in winter.
Signs Your Home Is Too Hot for the Monstera
- Brown, dry, crispy patches developing on the leaves, often starting at the edges
- Drooping caused by the plant losing water faster than its roots can replace it
- Soil drying out unusually quickly between waterings
If your home runs hot, particularly in summer or near a sunny window, moving the plant slightly further from the heat source, increasing air circulation with a fan (without blowing directly on the foliage), or temporarily using air conditioning in the room can help bring temperatures back into range.
Temperature Hazards to Avoid
- Cold draughts from open windows, exterior doors, or letterboxes in winter
- Leaves resting against cold, single-glazed window glass on winter nights
- Air conditioning units blowing cold air directly onto the foliage
- Proximity to radiators or other heat sources, which can cause localised overheating and drying even if the room as a whole is a comfortable temperature
If you are unsure whether a position is suitable, a simple room thermometer placed near the plant for a day or two, including overnight, will reveal whether temperatures are dipping into risky territory.
During winter it is normal for growth to slow considerably; this is not a problem in itself, provided temperatures stay above the danger threshold.
What Humidity Does a Monstera Need?
The Monstera thrives at humidity levels between 60 and 80%, reflecting the humid tropical rainforest environments it comes from.
Most UK homes sit well below this range, particularly in winter when central heating dries the air considerably.
Fortunately, the Monstera is fairly adaptable and can tolerate humidity as low as around 40% without serious harm. Below that threshold, however, you will start to see the effects on the foliage.
Signs Your Monstera Needs More Humidity
- Crispy, brown edges and tips on the leaves
- Leaves that feel dry, thin, or papery rather than firm and glossy
- Soil drying out faster than usual between waterings
- New leaves emerging smaller than expected, or failing to unfurl fully
Signs Your Home Is Too Humid
Although less common than low humidity in most homes, it is possible to provide too much moisture, particularly in small, poorly ventilated spaces such as bathrooms.
Signs of excessive humidity combined with poor airflow include:
- Mould developing on the leaves or on the surface of the soil
- Soggy stems and an increased risk of root rot
- Leaves that feel persistently damp and develop a dark, water-soaked appearance
- Yellowing and drooping despite otherwise correct watering
If you notice these signs, improve airflow around the plant with a small fan on a low setting, space plants further apart if they are grouped closely, and avoid misting in the evening, since damp leaves overnight encourage fungal problems.
How to Increase Humidity for a Monstera
- Use a humidifier: A small ultrasonic humidifier placed near the plant is the most effective and consistent way to raise humidity. It requires far less daily effort than misting and maintains a steadier level over time. Aim to keep the unit a short distance from the foliage so condensation does not form directly on the leaves.
- Mist the leaves: Misting provides a temporary humidity boost but needs to be done consistently to have any meaningful effect. Mist in the morning so the leaves have time to dry before nightfall, which helps prevent fungal issues developing on damp foliage overnight.
- Use a pebble tray: Fill a shallow tray with pebbles and add water up to just below the top of the pebbles, then stand the pot on top, ensuring the base of the pot does not sit directly in the water. As the water evaporates, it raises the humidity immediately around the plant without the roots sitting in standing water.
- Group plants together: Plants release moisture through their leaves via transpiration, so grouping several houseplants together creates a localised pocket of higher humidity. This works particularly well in smaller rooms, though make sure there is still enough airflow between plants to avoid fungal problems.
- Leave bathroom or kitchen doors ajar: These rooms often run more humid than the rest of the home due to cooking and showering, so positioning a Monstera nearby (with adequate light) or leaving the door open after use can give a gentle, ongoing humidity boost.
Humidity needs often shift with the seasons. In the UK, central heating in winter can dry the air significantly even if summer humidity was adequate, so it is worth checking levels with an inexpensive hygrometer through the colder months and adjusting your routine accordingly.
How to Fertilise a Monstera
A Monstera in active growth produces large leaves quickly and needs a steady supply of nutrients to sustain that growth.
Without adequate feeding, growth slows, new leaves emerge pale and undersized, and the plant gradually loses its vigour and colour.
Synthetic vs Organic Fertiliser
Synthetic fertilisers contain concentrated, fast-acting nutrients in the same basic forms as organic options, and tend to produce the most rapid visible growth.
They are best suited to growers who want maximum growth, are comfortable following label instructions precisely (since synthetic fertilisers are easier to overdose), and whose potting mix is relatively nutrient-poor and needs a reliable top-up.
When using a synthetic fertiliser, always follow the manufacturer’s instructions on dilution and frequency exactly, and start with a smaller-than-recommended dose the first few times you use a new product to gauge how the plant responds.
Organic fertilisers, such as worm castings, fish emulsion, or seaweed-based feeds, release nutrients more slowly and tend to be gentler on the roots, making them harder to overdose.
They are a good choice if you have previously damaged a plant with synthetic feed, want to support the broader microbial life in the potting mix, and are happy to feed smaller amounts more regularly.
Both types can be combined, but if you do, use smaller amounts of each than you would if using either alone, to avoid overloading the plant.
For more on choosing between these, see our guide on what fertiliser to use for your Monstera.
How Often to Feed a Monstera
Feed your Monstera roughly every two to four weeks during spring and summer using a balanced liquid fertiliser diluted to around half the strength recommended on the label.
Stop feeding entirely in autumn and winter, when the plant’s growth slows naturally and it cannot make use of the extra nutrients, increasing the risk of fertiliser burn instead.
Beyond the basic seasonal pattern, a few other factors affect how often to feed:
- Potting mix type: Soilless, bark-based mixes generally hold fewer nutrients than soil-based mixes and may need slightly more frequent feeding to compensate.
- Light source: A plant relying on natural light will slow down in winter and need less feeding, whereas a plant under a consistent grow light may continue growing steadily and can be fed on a more regular schedule year-round.
- Fertiliser strength: Stronger, more concentrated products should be used less often; gentler organic feeds can often be applied more frequently at lower doses.
Signs of Overfeeding
- A white, crusty deposit forming on the surface of the soil or around the rim of the pot
- Leaves wilting despite the soil being adequately moist
- Yellowing that progresses into browning, often starting at the leaf tips and edges (a classic sign of fertiliser burn)
- Growth suddenly stalling despite regular feeding
If you suspect overfeeding, flush the soil by running plain water slowly through the pot for around ten minutes, allowing it to drain freely from the bottom each time.
Let the mix dry out somewhat before watering again, and reduce both the strength and frequency of feeding going forward, ideally returning to a half-strength dose no more than monthly until the plant recovers.
Signs of Underfeeding
- Pale, washed-out new growth that lacks the deep green of established leaves
- Noticeably slower growth during what should be the active growing season
- New leaves that are consistently smaller than those the plant has previously produced
If these signs appear during spring or summer and watering and light are already correct, introducing or slightly increasing a balanced liquid feed at half strength is a reasonable first step.
How to Repot a Monstera
A Monstera needs repotting once its roots have substantially filled the current pot.
Leaving a plant root-bound for too long restricts further growth, reduces its ability to take up water and nutrients efficiently, and increases the risk of the potting mix compacting and becoming waterlogged.
Most Monsteras need repotting every one to two years, with spring being the ideal time, as the plant is entering active growth and can recover from the disturbance quickly.
Signs Your Monstera Needs Repotting
- Roots growing out of the drainage holes at the base of the pot
- Roots visibly circling at the surface of the soil
- Growth that has slowed significantly despite otherwise good care
- Water running straight through the pot without being absorbed, suggesting roots have displaced most of the potting mix
Once a Monstera reaches a mature size, typically once its stem or root mass has a diameter of around 20cm (8 inches) or more, you can largely stop repotting into ever-larger pots.
Instead, top-dress the plant each year by removing the top few centimetres of old mix and replacing it with fresh potting mix, which replenishes nutrients without the disturbance of a full repot.
How to Repot a Monstera, Step by Step
- Choose the right pot. Select a new pot that is only one to two inches wider and deeper than the current one, with drainage holes. Going much larger than this creates a large volume of mix that stays wet for far longer than the smaller root system can use, increasing the risk of root rot.
- Water the day before. Watering the plant the day before repotting helps the root ball hold together as a single mass, making it easier to remove cleanly from the old pot.
- Prepare fresh mix. Make up a fresh batch of aroid potting mix (see the Soil section above) and add a layer to the bottom of the new pot, filling it to roughly a quarter of its depth. If your plant uses a support pole, position the pole now before adding the plant.
- Remove the plant from its old pot. Tip the pot onto its side and gently loosen it by squeezing the sides or tapping the base, then ease the plant out while supporting the base of the stems. Avoid pulling on the stems themselves, as this can damage them or tear roots.
- Inspect the roots. Healthy roots are firm and range from white to light tan in colour. Trim away any roots that are dark, mushy, or have an unpleasant smell using sterilised scissors or shears, as these are signs of root rot and should not be left in contact with fresh mix.
- Position the plant in the new pot. Place the root ball on top of the layer of fresh mix, then fill in around it with more mix, firming gently as you go. Leave around two inches of space between the top of the soil and the rim of the pot to make watering easier.
- Water thoroughly. Water until it runs from the drainage holes, then return the plant to its previous position or another spot with similar light. It is normal for a recently repotted plant to pause growth for a short period while it settles in; avoid feeding for two to four weeks after repotting to let the roots recover undisturbed.
If You Are Growing Multiple Monsteras
If you are considering growing more than one Monstera in the same pot for a fuller look, keep in mind that they will compete for water, nutrients, and root space, and the pot will need repotting sooner than it would for a single plant.
Whatever pot you choose, prioritise drainage holes above all else, since this is the single biggest factor in preventing waterlogging regardless of pot material or style.
How to Prune a Monstera
Pruning keeps a Monstera at a manageable size, removes damaged or diseased growth, and encourages the plant to put out new leaves lower down on the stem rather than putting all of its energy into upward growth.
Left unpruned in good conditions, a Monstera can grow tall enough to reach the ceiling and take over a corner of a room, with stems that become long, bare, and leggy at the base.
Why Pruning Matters
- Aesthetics: The Monstera is grown for its striking, fenestrated foliage. Regular pruning removes tired, yellowing, or damaged leaves so the plant always looks its best, and encourages a fuller, bushier shape rather than a few long, sparse stems.
- Growth control: A Monstera can grow several metres tall given the right conditions. Pruning the main growing tips redirects the plant’s energy into side shoots, curbing vertical growth and encouraging a fuller, more compact form.
When to Prune
Prune in spring or early summer, when the plant is actively growing and will recover from any cuts quickly.
Pruning in late winter, just before the growing season begins, also works well.
Avoid pruning during periods of extreme heat or cold, or during the dormant winter months, except to remove diseased, damaged, or dead material that genuinely cannot wait until the next growing season.
How to Prune a Monstera, Step by Step
- Gather your supplies. You will need a clean, sharp knife, scissors, or secateurs, isopropyl alcohol for sterilising, and a pair of gloves. Wipe the blades with alcohol before you start and between cuts on different plants to avoid spreading any pathogens.
- Protect yourself. Wear gloves throughout, since the sap contains calcium oxalate crystals that can irritate the skin. If you are sensitive, consider wearing eye protection too, particularly when cutting thicker stems where sap may spray.
- Identify the nodes. Nodes are the slightly raised, lighter-coloured sections along the stem from which leaves, aerial roots, and new shoots emerge. Every leaf is associated with a node, and a single stem can have multiple nodes along its length.
- Remove unhealthy leaves first. Cut away any leaves that are yellowing, browning, diseased, or showing soft, decayed patches, cutting close to the base of the leaf stalk where it joins the main stem.
- Prune stems for shape and size. For stems that are too long, tangled, growing in an unwanted direction, or simply too tall, cut just below a node using a clean, flat cut. Cutting below (rather than through) a node preserves the plant’s ability to produce new growth from that point, and a piece with a healthy node attached can often be used for propagation.
- Trim excess aerial roots if needed. Aerial roots that have grown long and are getting in the way can be trimmed back without harming the plant; they are not essential to the plant’s survival indoors, though they do help anchor it to a support.
- Dispose of cuttings safely. Compost healthy plant material or dispose of it with general garden waste, keeping all cuttings away from pets and children due to their toxicity. If a cutting includes a healthy node, set it aside for propagation instead of discarding it.
How to Support a Monstera
In the wild, the Monstera is a climber, using its aerial roots to attach to trees and other structures as it grows toward the light.
Indoors, providing a support structure allows the plant to grow in the way it naturally wants to, and this has a direct, positive effect on leaf size and the development of fenestrations, since climbing plants generally produce larger, more deeply split leaves than those left to sprawl unsupported.
Moss Poles and Coir Totems
A moss pole or coir-wrapped totem is the most effective support for an indoor Monstera.
These poles hold moisture, which encourages the plant’s aerial roots to attach to the surface and grow into it, anchoring the plant securely as it climbs.
To set one up, insert the pole into the pot close to the main stem (taking care not to damage the root ball), then loosely tie the stem to the pole at several points using soft plant ties or strips of cloth, leaving room for the stem to thicken as it grows.
Mist the pole occasionally to keep it slightly damp, which helps aerial roots take hold more readily.
Trellises, Wall Supports, and Canes
A trellis, wall-mounted support, or simple bamboo cane can also work well, particularly for plants that are being trained to grow along a wall or in a particular direction.
As with a moss pole, tie the stems loosely to the support as they grow, checking and adjusting the ties periodically so they do not constrict the stem as it thickens.
Stems That Bend or Flop
If a Monstera develops long, floppy stems that bend under their own weight rather than growing upright, this is usually a sign that the plant either lacks adequate support or is reaching for more light than it is currently receiving.
Adding a support structure for the existing growth, combined with moving the plant to a brighter spot if needed, will usually encourage straighter, more upright growth over time.
In some cases, very long, leggy stems may be better pruned back to encourage fresh, more compact growth rather than trying to support an already-overgrown stem.
Encouraging More Leaves
If your Monstera is producing fewer leaves than expected, or each new leaf is noticeably smaller than the last, review the core conditions covered earlier in this guide in this order: light levels first, then watering consistency, then feeding during the growing season, and finally whether the plant has outgrown its pot.
Providing a support structure for the plant to climb can also help, since climbing growth tends to produce larger leaves than growth left to trail or sprawl.
How to Propagate a Monstera
There are two ways to create a new Monstera plant: from a stem cutting or from seed.
Propagating from cuttings is by far the more common and reliable method, is much faster, and is the only way to propagate variegated forms, since variegation does not reliably pass through seed.
The Importance of the Node
Every cutting must include at least one node to have any realistic chance of rooting.
A node is the slightly raised, lighter-coloured section of stem from which leaves, aerial roots, and new shoots emerge.
A leaf or stem section without a node attached will not develop roots and will not grow into a new plant, no matter how it is treated, so always check that a cutting includes a node before attempting to propagate it.
Stages of a Propagated Cutting
- The fresh cutting: Immediately after taking a cutting from the parent plant, it has no soil roots of its own. It may have aerial roots, but these alone cannot sustain the cutting long-term. At this stage the cutting needs to be placed into a suitable rooting medium as soon as possible.
- The rooted cutting: Once placed in a suitable medium, the cutting develops its first soil roots, typically starting as a single white root from the stem or from an existing aerial root, which then branches into finer feeder roots that take up water and nutrients.
- The established cutting: A cutting is ready to move to its final pot once its roots are several inches long. Handle the roots gently during this move, since some root loss during transplanting is normal but should be minimised, and the cutting is only truly established once it adapts to the new medium and resumes active growth.
- The new plant: Once the cutting begins producing new leaves in its final pot, propagation has been successful, and from this point it can be cared for using the same guidance as any other Monstera in this guide.
Choosing the Right Cutting
Propagate during the plant’s active growing season, typically spring or summer, when rooting happens fastest, though propagation is still possible in winter, just more slowly.
Aim for a cutting with two to three leaves and the same number of nodes; this gives the cutting enough leaf area to photosynthesise and sustain itself while it develops roots, and provides a margin of error if one node fails to root.
There are three broad types of cutting, each with different characteristics:
- Top cuttings: Taken from the growing tip of a stem, these root and establish fastest, typically producing a new leaf within about six weeks.
- Mid cuttings: Taken from the middle of a stem, these take roughly twice as long as top cuttings to produce a new leaf, since the cutting effectively has to restart in terms of leaf size and maturity.
- Stem (node-only) cuttings: These consist of a node with no leaves attached. Because they cannot photosynthesise until new growth emerges, they are the slowest of the three, sometimes taking up to four months to produce a new leaf, but they are useful when leaf material is limited.
Taking and Preparing the Cutting
- Make the cut. Use a clean, sharp knife or shears, sterilised with isopropyl alcohol. Cut a little below the lowest node you want to keep, including the axillary bud just above each node in the section you retain, since this is where new growth will emerge.
- Allow the cut to callus slightly. It is normal for the cut surface to change colour slightly as it is exposed to air; this is a natural part of the healing process and not a cause for concern.
- Apply rooting hormone (optional). Dipping the cut end in a rooting hormone powder or gel can speed up root development and offers some protection against rot at the cut surface, though many cuttings will root successfully without it.
- Choose a propagation method. Select a method based on what you have available and how hands-on you want to be (see below). Whichever method you choose, the cut end of the stem should stay in contact with a consistently moist (but not waterlogged) medium, since both excessive dryness and excessive wetness at the cut surface increase the risk of rot.
Propagation Methods
- Water propagation: Place a node-bearing cutting in a clean jar of water, positioned in bright, indirect light, with the node submerged but as much foliage as possible kept above the waterline. Change the water every three to five days to keep it fresh and oxygenated. Roots typically begin to appear within two to four weeks, and the cutting can be moved to soil once roots reach two to three inches long. The main downside of this method is that roots grown in water can struggle to adapt to soil conditions, so transition gradually if possible, and be aware that roots can suffer from low oxygen levels if the water is not changed regularly. For a closer look at this approach, see growing a Monstera in water.
- Soil propagation: Plant the cutting directly into a moist, free-draining propagation mix, such as equal parts coco coir and perlite. Covering the pot with a clear plastic bag helps maintain humidity around the cutting while it roots; remove the bag for around 30 minutes a day to allow fresh air in and prevent fungal issues. Rooting typically takes four to eight weeks. This method skips the need to transplant from water to soil later, but it is harder to monitor root development since the roots are hidden.
- Moss propagation: Wrap the node in damp sphagnum moss, which holds moisture well and creates a consistently humid micro-environment around the cutting. As with soil propagation, maintaining the right moisture level, damp but not saturated, takes a little practice, but moss is excellent at supporting root development once the balance is right.
- Perlite propagation: Insert the node into moist perlite, which is highly absorbent yet allows plenty of air to reach the developing roots, helping to prevent fungal problems. The main drawback is that, like soil, it is difficult to check on root progress without disturbing the cutting.
- Air layering: Rather than removing a cutting first, this method involves wrapping moist sphagnum moss around a node while it is still attached to the parent plant, then covering it tightly with clear plastic. Roots develop in the moss over several weeks while still supported by the parent plant. Once roots are two to three inches long, the rooted section is cut away from the parent as a fully formed plantlet. This produces the most developed root system of any method before the cutting is separated, but it does not work on cuttings that lack any aerial root growth at the node.
Aftercare for Cuttings
A cutting does not need feeding until it has developed roots, since it cannot take up nutrients without a root system to absorb them.
Once roots are well established and the cutting has been moved to its final pot and potting mix, you can begin a normal feeding routine after a settling-in period of two to four weeks, following the fertiliser guidance earlier in this guide.
Propagating a Monstera from Seed
Mature Monsteras can produce seeds, which can be sourced from a flowering plant, an online supplier, or a local nursery.
Seed propagation is slower and generally more challenging than propagation from cuttings, and it is worth noting that variegated Monstera cannot be reliably grown from seed; variegation must come from a cutting taken from a variegated parent.
- Source fresh seeds. Monstera seeds have a short shelf life and viability drops quickly, so plant them as soon as possible after obtaining them.
- Soak the seeds. Soak the seeds in lukewarm water for around 12 hours. They will swell slightly as they absorb water.
- Sow into a small container. Move the soaked seeds into a small amount of moist, free-draining soil in a small pot, taking care not to use so much soil that the seeds end up sitting in standing water. Place the container in a warm room in bright, indirect light.
- Maintain consistent moisture. Keep the soil moist but allow the surface to dry slightly between waterings, following the same general watering principles described earlier in this guide.
- Wait for germination. Seedlings typically appear within two to three weeks. Once established, transition the seedling to the standard Monstera care described throughout this guide, and repot as it grows.
Troubleshooting Cuttings That Will Not Root
If a cutting shows no sign of root development after several weeks, check the basics first: confirm the cutting includes a healthy node, that the cut surface has not rotted (it should look firm, not soft or discoloured beyond the initial colour change), and that the medium has stayed consistently moist without becoming waterlogged.
Cuttings taken during the dormant winter months will simply take longer, so patience is often the main requirement before assuming something has gone wrong.
Common Monstera Pests and How to Deal with Them
A healthy Monstera growing in good conditions is reasonably resistant to pests, but no houseplant is completely immune.
Catching an infestation early, before it has a chance to spread or multiply, makes treatment far more straightforward and reduces the risk of lasting damage to the plant.
Regularly inspecting the undersides of leaves, the stems, and the soil surface, ideally each time you water, is the best way to spot problems early.
Scale Insects
Scale insects attach themselves to stems and the undersides of leaves and feed on plant sap.
They are easy to overlook because the adults do not move and are often mistaken for a natural part of the plant, particularly the hard-shelled varieties, which sit under a protective covering and do not produce honeydew.
Soft scales, by contrast, are flat to rounded, produce sticky honeydew, and have a waxy coating.
Scales reproduce by laying large numbers of eggs, which hatch into young that pierce the plant to feed, exposing it to secondary infections, before maturing into adults that develop their own protective coverings and begin the cycle again.
Signs of infestation:
- Yellowing leaves
- General wilting
- Leaf drop
- Changes in leaf colour
- Stunted growth
- Small yellow spots on the foliage
Inspect the stems, leaf joints, and younger growth closely, as scales tend to favour these areas.
Treatment:
- Isolate the affected plant from other houseplants
- Prune away heavily affected sections if the infestation is localised
- Scrape visible scales off the plant by hand or with a soft brush
- Wipe affected areas with rubbing alcohol on a cotton pad, which dissolves the protective coating of many scales and kills them on contact
- Follow up with a horticultural soap or insecticidal soap applied across the whole plant
Recheck the plant regularly after treatment, since even a small number of surviving scales can re-establish an infestation by laying more eggs.
Fungus Gnats
Unlike most other Monstera pests, fungus gnats do not feed directly on the plant itself.
The adults are small, dark grey flies with long legs and clear wings that live and breed in the top layer of consistently damp soil, while the pale, clear-bodied larvae with shiny black heads feed on fine roots and organic matter in the soil, which can weaken the plant and create entry points for disease.
Fungus gnats reproduce quickly, laying around 300 eggs at a time, with larvae emerging within four to six days and the full adult cycle completing in about four weeks, so populations can build up fast if conditions remain consistently damp.
Signs of infestation:
- General wilting
- Stunted growth
- Yellowing leaves
- Damage to young growth
- Small flies visible on or near the soil surface, especially when the soil is disturbed or watered
Treatment:
- Allow the top two inches of soil to dry out fully between waterings, since this is the single most effective long-term fix, as fungus gnats cannot establish in consistently dry soil
- Water from the bottom (by standing the pot in a tray of water until the soil absorbs what it needs) rather than from the top, which keeps the surface drier
- Use yellow sticky traps to catch adult gnats and monitor how the population responds to changes in your watering routine
- A mix of apple cider vinegar and a drop of dish soap left in a shallow dish nearby can attract and trap adults
- An appropriate insecticide can reduce adult numbers but will not affect larvae already in the soil, so it should be combined with the watering changes above for a lasting fix
Spider Mites
Spider mites are extremely small and highly mobile, spreading easily between plants via fine webbing, air currents, and by hitching a ride on clothing, fur, or skin.
Because a single mite found on one plant can indicate the early stages of a wider spread, acting quickly is important.
They are difficult to see with the naked eye, so look instead for indirect signs: fine webbing on the undersides of leaves or between stems, a sandy or gritty texture to the leaf surface, and honeydew.
Holding affected leaves over a sheet of white paper and gently shaking them can dislodge mites, which then appear as tiny moving reddish-brown specks on the paper, a useful confirmation if you suspect an infestation but cannot see anything on the plant directly.
Spider mites typically lay eggs over winter, which hatch as spring begins, and can reproduce very quickly in warm conditions, feeding on plant tissues and fluids and weakening the plant as they do so.
Signs of infestation:
- Leaf curling
- Leaf discolouration
- Tiny spots or stippling on the leaves
- Leaf drop
Treatment:
- Increase humidity around the plant, since spider mites struggle in moist air and thrive in dry conditions
- Wipe down affected leaves with a damp cloth to physically remove mites and webbing
- Hose down the plant (in a shower or sink, or outdoors in mild weather) to dislodge mites in larger numbers
- Treat with horticultural oil or insecticidal soap, repeating weekly until no further signs of infestation appear
- Consider introducing predatory mites for persistent infestations on larger plant collections
Be cautious with neem oil, since it can also affect the natural predators of spider mites, potentially making a persistent infestation worse rather than better.
Aphids
Aphids are small, soft-bodied insects that cluster on new growth and the undersides of leaves, feeding on plant sap with needle-like mouthparts.
They come in a range of colours, including black, red, brown, green, and yellow, often have small projections (cornicles) at the rear of the body, and some forms develop wings to spread to new plants. They reproduce rapidly, so an infestation can grow large quickly if left unaddressed.
Signs of infestation:
- General wilting
- Yellowing leaves
- Slowed growth
- Curling leaves
Treatment:
- A strong jet of water from a hose or sink sprayer will dislodge most aphids from the plant
- Follow up with insecticidal soap applied to all leaf surfaces, with particular attention to the undersides of leaves and new growth, where aphids cluster most
- Repeat treatment every few days until no further aphids are visible
- Encouraging natural predators such as ladybirds, where practical, can help keep populations in check on a wider plant collection
Thrips
Thrips are slim, fast-moving insects that feed on leaf tissue, leaving fine silvery or white streaks and patches on the leaf surface where they have removed cell layers while feeding.
The adults are typically dark brown or black and can fly, while the pale larvae tend to cluster together. Thrips can also spread plant viruses between plants, so prompt action matters.
Signs of infestation:
- Silvery or white streaks and patches on the leaves
- Tiny black specks on the foliage (thrips droppings)
- Distorted or stunted new growth
- General decline in leaf appearance and vigour
Treatment:
- Isolate the affected plant immediately to prevent spread to others
- Prune away the most heavily affected leaves
- Hose down the plant to physically remove as many thrips as possible
- Follow up with horticultural soap, repeating as needed, and continue monitoring closely for several weeks
Common Monstera Problems and What Causes Them
Many Monstera problems share overlapping symptoms, which is why diagnosis usually means working through several possible causes rather than jumping to the first one that comes to mind.
If your plant has declined significantly, our guides to reviving a dying Monstera and saving a damaged plant walk through the recovery process in more depth.
The table below summarises the most common visible problems and their typical causes; more detail on each follows.
| Problem | Likely Causes |
|---|---|
| Yellow leaves | Overwatering or root rot, poor potting mix, blocked or inadequate drainage, insufficient light, pest infestation, or natural ageing of older lower leaves |
| Brown leaves | Low humidity (tips and edges), inconsistent watering, direct sun damage, cold stress, or root rot (patches in the middle of the leaf) |
| Black leaves | Root rot from sustained overwatering, frost or cold draught damage, or bacterial/fungal disease |
| Curling leaves | Underwatering, low humidity, high temperatures, poor potting mix, or root damage from overfeeding |
| Drooping leaves | Underwatering, root rot, compacted soil, extreme temperatures, transplant shock, or pest damage |
| Cracking or ripping leaves | Low humidity, rough handling, or the plant brushing against furniture or catching draughts |
| Leggy growth | Insufficient light causing the plant to stretch toward a light source |
| No new growth | Insufficient light, a pot that is too small or compacted soil, root rot, pest infestation, or normal winter dormancy |
| Lack of fenestrations | The plant is under two to three years old, insufficient bright indirect light, or inadequate nutrition |
Yellow Leaves
Yellowing is the most common visible sign of trouble in a Monstera, and the most frequent cause is overwatering or poor drainage leading to root rot.
However, yellowing can also result from insufficient light, a nutrient deficiency, a poor potting mix, or pest infestation, so check the soil moisture and roots first, then work through light, feeding, and pests if watering checks out.
It is also normal for the occasional oldest, lowest leaf to yellow and drop as the plant matures and redirects energy to new growth, which is not a cause for concern on its own.
Brown Leaves
Brown leaf tips and edges most often point to low humidity or inconsistent watering, where the plant experiences alternating periods of too dry and too wet.
Brown patches appearing in the middle of a leaf, rather than at the edges, are more often linked to root rot, direct sun damage, or cold stress, so consider the position of the affected leaves and recent care history when diagnosing.
Black Leaves
Blackening is usually a sign of something more serious than simple browning.
The most common causes are root rot following sustained overwatering, frost or cold draught damage, and bacterial or fungal disease.
If you notice blackening, check the roots for rot, review recent temperatures the plant has been exposed to, and isolate the plant if you suspect disease, since some fungal and bacterial issues can spread to nearby plants.
Curling Leaves
Curling typically signals that the plant is losing moisture faster than its roots can replace it.
The most common causes are underwatering, low humidity, high temperatures, a poor potting mix that drains too quickly or too slowly, and root damage caused by overfeeding.
Address watering and humidity first, since these are the most frequent culprits, before considering feeding history and the potting mix.
Drooping Leaves
Drooping that does not recover shortly after watering often points to a root-level problem rather than a simple watering issue at the surface.
Root rot, compacted soil, extreme temperatures, transplant shock following a recent repot, and pest damage can all cause drooping.
If the plant was recently repotted, some drooping for a week or two is normal as the roots settle; if drooping persists well beyond that or the plant was not recently disturbed, check the roots for rot.
Cracking and Ripping Leaves
Physical damage to Monstera leaves, including cracking along the fenestrations or tearing at the edges, can result from low humidity making the leaf tissue more brittle, rough handling when moving or cleaning the plant, or the plant being positioned where it catches draughts or repeatedly brushes against furniture, curtains, or walls as it grows.
Increasing humidity and giving the plant more room to expand can reduce further damage, though existing cracks and tears will not heal and will remain as the leaf matures.
Leggy Growth
A Monstera that produces long stems with widely spaced leaves and little foliage in between is described as leggy, and this almost always results from insufficient light, with the plant stretching toward the nearest light source it can find.
Moving the plant closer to a bright window, or adding a grow light, will typically slow leggy growth over time and encourage more compact, leafy development on new growth, though existing leggy stems will not become bushier retroactively without pruning.
No New Growth
If a Monstera has stopped producing new leaves entirely during what should be its active growing season, the likely causes are insufficient light, a pot that has become too small or a potting mix that has compacted, or a root system affected by root rot or pest damage.
It is also worth ruling out the time of year: during autumn and winter, a temporary pause in growth is entirely normal and does not necessarily indicate a problem.
Lack of Fenestrations
Most people grow a Monstera specifically for its fenestrations, so a lack of splitting can be disappointing.
The most common reason is simply that the plant is not yet mature enough; fenestrations typically begin between two and three years of age, regardless of care quality.
If the plant is mature enough but still producing solid leaves, insufficient bright indirect light is the next most likely cause, followed by inadequate nutrition.
Reviewing the light and feeding sections of this guide is the best starting point if your plant should be old enough to fenestrate but is not.
How to Keep Monstera Leaves Clean and Glossy
Dust accumulates on Monstera leaves over time, which reduces the amount of light the plant can absorb for photosynthesis and makes the foliage look duller than it should.
Cleaning the leaves every few weeks keeps the plant looking its best and helps it function efficiently.
The simplest and safest approach is to wipe each leaf gently with a soft, damp cloth, working from the base of the leaf toward the tip while supporting the leaf from underneath with your other hand to avoid tearing it, particularly around the fenestrations where the leaf tissue is thinner and more delicate.
For very dusty plants, a quick rinse under a lukewarm shower can be an efficient alternative to wiping each leaf individually.
Avoid commercial leaf shine products, as these can clog the small pores on the leaf surface that the plant uses for gas exchange, interfering with its ability to photosynthesise and respire properly.
Clean water and a soft cloth are all that is needed to keep the foliage glossy.
Where to Place a Monstera in Your Home
Position affects nearly every other aspect of care, since light, temperature, humidity, and watering frequency are all influenced by where the plant sits in the home. The key principles are:
- Choose a bright room with good natural light, but avoid spots where direct sun falls on the leaves for extended periods
- Keep the plant away from radiators, air conditioning units, and draughty windows or doors, all of which can cause rapid swings in temperature and humidity around the foliage
- Allow enough space for the plant’s leaves to spread without constantly touching walls, furniture, or curtains, both for aesthetic reasons and to reduce physical damage to the leaves over time
- Position the plant somewhere you pass regularly, so checking the soil and spotting early signs of pests or problems becomes part of your everyday routine rather than something you have to remember to do separately
In smaller homes or apartments, a Monstera can still thrive with some planning: prioritise the brightest available spot that meets the light guidance above, use vertical space with a moss pole or trellis rather than letting the plant sprawl outward, and be mindful of how close the plant sits to radiators or single-glazed windows, since smaller rooms often experience more pronounced temperature swings near these features.
For more tips tailored to compact spaces, see our guide to Monstera care for beginners in small apartments.
Frequently Asked Questions
Is a Monstera easy to care for?
Yes. The Monstera is one of the more forgiving tropical houseplants available.
Its two most important needs are appropriate indirect light and careful, soil-led watering, and getting these two factors right means the plant will tolerate minor inconsistencies in other areas such as humidity or feeding.
It is a good choice for beginners as well as more experienced plant owners looking for a striking, low-maintenance statement plant.
How fast does a Monstera grow?
A Monstera in good conditions, with adequate light, warmth, and regular feeding during the growing season, can produce roughly one new leaf every four to six weeks.
Growth slows considerably in autumn and winter, sometimes pausing altogether.
Younger plants generally grow more slowly than established ones, since mature plants have a larger root system and leaf area to support faster development.
Why is my Monstera not fenestrating?
Monstera leaves typically begin developing splits and holes once the plant reaches two to three years of age; before that point, leaves remain solid regardless of care quality.
If your plant is mature enough but still not fenestrating, insufficient bright indirect light is the most common cause, followed by inadequate nutrition.
Reviewing both the light and fertiliser sections of this guide is the best starting point.
Should I mist my Monstera?
Misting can provide a short-term humidity boost and can form part of a wider humidity routine, but it does not replace a humidifier for maintaining consistently high humidity over time, since the effect of misting fades within a short period.
If you do mist, do so in the morning so the leaves have time to dry during the day, reducing the risk of fungal issues developing on damp foliage overnight.
Can a Monstera purify the air?
Houseplants, including the Monstera, have a modest air-purifying effect in enclosed spaces by absorbing small amounts of certain airborne compounds and releasing oxygen through photosynthesis.
However, the effect in a typical home is generally small compared with the impact of regular ventilation, so a Monstera should be seen as a complement to good airflow rather than a replacement for it.
Is Monstera toxic?
Yes. All parts of the Monstera contain microscopic calcium oxalate crystals, which cause irritation, burning, and swelling in the mouth, throat, and digestive tract if chewed or swallowed, and can also irritate skin and eyes on contact with the sap.
Keep the plant, fallen leaves, and any cuttings out of reach of cats, dogs, and young children, and wear gloves when pruning or propagating.
How do I know where to cut when I prune my Monstera?
Always cut just below a node, the slightly raised section of stem from which leaves and roots emerge.
Cutting through a node destroys the plant’s ability to produce new growth from that exact point, so aim to leave the node intact on the remaining plant, or, if you want to use the cutting for propagation, ensure the node is included in the section you remove rather than the section left behind.
Can I keep my Monstera outside?
In the UK, a Monstera can be moved outdoors during the warmer months, provided it is kept in a sheltered, shaded position away from direct sun and strong wind.
It should be brought back indoors well before night-time temperatures begin to drop in autumn, since the plant has very little tolerance for cold and can suffer lasting damage even from a single cold night.
Why are the leaves on my new Monstera smaller than on the one I saw in the shop?
A young plant, or one that has recently moved to a new environment with different light conditions, will often produce smaller leaves for a period before settling in and beginning to size up, particularly once it is given a support structure to climb and consistent bright indirect light.
Key Takeaways
- Water when the top two inches of soil feel dry, not on a fixed schedule. Overwatering and poor drainage are the leading causes of Monstera decline.
- Provide bright, indirect light for four to six hours daily. Direct sun scorches the leaves, while low light produces small, unsplit foliage and very slow growth.
- Use a chunky, free-draining aroid mix. A standard multipurpose compost is too dense and holds too much moisture for a Monstera’s roots.
- Keep temperatures between 18 and 30°C and avoid cold draughts. Below around 10°C the plant is at serious risk of lasting damage or death.
- Aim for 60 to 80% humidity. Use a humidifier, pebble tray, plant grouping, or regular misting to raise levels if your home runs drier than this.
- Feed every two to four weeks during spring and summer at half strength, and stop in autumn and winter. Both over- and underfeeding produce visible symptoms that can be corrected once recognised.
- Repot every one to two years in spring, moving up only one pot size at a time. Top-dress mature plants with fresh mix instead of repotting indefinitely.
- Prune in spring with sterilised tools, cutting just below a node. Wear gloves throughout, since the sap can irritate skin.
- Provide a moss pole, totem, or trellis. Climbing growth produces larger leaves with more pronounced fenestrations than unsupported, sprawling growth.
- Inspect leaves and stems regularly for pests. Early treatment of scale, fungus gnats, spider mites, aphids, and thrips is far more effective than treating an established infestation.
- Remember that the plant is toxic. Keep it, its cuttings, and fallen leaves out of reach of pets and children at all times.
With consistent attention to light, watering, and humidity, a Monstera will reward you with large, glossy, deeply fenestrated leaves for years to come. Happy growing!
