Why is my Monstera Not Growing & How to Fix it

If you spend any time looking at monstera accounts on Instagram, it is easy to assume these plants more or less grow themselves.

Scroll past a few glossy, fenestrated leaves and you could be forgiven for thinking your own cutting will do the same with minimal effort.

In reality, most “my monstera isn’t growing” questions trace back to one of a handful of fixable causes, and the fix is usually straightforward once you know what to look for.

Before assuming something is wrong, though, it is worth checking your expectations against reality.

A healthy monstera deliciosa growing in good conditions typically puts on around two feet of growth a year, and a ten-year-old specimen on someone’s feed will always dwarf a two-year-old plant growing exactly as it should.

If your plant’s growth genuinely seems to have stalled rather than simply being younger or smaller than the one you are comparing it to, the most common underlying causes are insufficient light, low humidity, incorrect watering, nutrient depletion, unsuitable temperature, seasonal dormancy, and a root system that has outgrown its pot.

This guide walks through each one, how to recognise it, and exactly what to do about it.

If your plant is a recently rooted cutting rather than an established specimen, there is also a separate section further down covering why new propagations often appear to stall before they ever get going.

1. Your Monstera Needs More Light

Light is the engine behind everything a monstera does.

Photons striking the leaves drive photosynthesis, the process by which the plant converts water, light, and nutrients into the carbohydrates it uses for energy, root uptake, and new growth.

Without enough light, that engine simply cannot run at full capacity, no matter how well you handle watering or feeding.

Signs Your Monstera Isn’t Getting Enough Light

A light-starved monstera tends to show a recognisable cluster of symptoms together, which helps distinguish it from other causes on this list.

Look out for slowed or stunted growth, smaller new leaves than the plant has previously produced, stems leaning persistently toward the nearest light source, leggy and weak stems that cannot support themselves, loss of variegation in variegated cultivars, and soil that stays wet for unusually long periods because the plant isn’t using water at its normal rate.

A consistently low-light plant is also more vulnerable to pest problems, since a weakened plant has less capacity to resist infestation.

How Much Light Does a Monstera Need?

Exact requirements vary by species, but for the common monstera deliciosa, bright indirect light is the target, replicating the dappled light it would receive beneath a forest canopy in its native range stretching from southern Mexico to Panama.

The light should be strong enough to drive vigorous growth without being so direct that it scorches the leaves.

As a placement guide:

For plants that need partial shade, roughly 4 hours of gentle light a day, position them near an east-facing window, ideally at least 4 feet back to avoid direct midday sun.

For plants that need partial sun, 4 to 6 hours, the same east-facing spot works, or you can use a south or west-facing window kept at a similar distance, watching for any sun-scorch and moving the plant back if you see it.

For the rare monstera species that genuinely want direct sun, a south-facing window with at least 6 hours of bright direct light is appropriate.

For lower-light tolerant species, a north-facing window suits growers in the northern hemisphere, while those in the southern hemisphere should reverse this and use a south-facing window, positioned roughly a foot from the glass.

If natural light is limited in your home, a full-spectrum grow light run for around 8 hours a day is an effective substitute.

For a detailed breakdown of fixtures that work well for indoor monstera, see our grow light buying guide, and for a deeper dive into placement by aspect and season, our guide on monstera light requirements and where to place your monstera cover this in more detail.

2. Your Monstera Needs More Humidity

Monstera deliciosa is native to tropical forest environments, where humidity sits consistently high.

Indoors, low humidity disrupts the balance between how much water the leaves lose through transpiration and how much the roots can take up to replace it, and that imbalance shows up directly as poor growth.

Signs of Low Humidity Stress

Watch for browning along the leaf edges and tips, drooping that doesn’t resolve with watering, and growth that has noticeably slowed compared to the plant’s usual pace.

Low humidity alone will not kill a healthy monstera, but it will reliably hold back growth even when every other care factor is correct.

What Humidity Level Does a Monstera Need?

The widely recommended target for monstera deliciosa is 60% to 80% relative humidity.

Below around 40%, growth typically struggles to keep pace even with otherwise good care.

Watering more to compensate for dry air does not solve the underlying problem, since the issue is the rate of water loss from the leaves rather than insufficient water at the roots.

A hygrometer is the simplest way to find out where your home actually sits, since humidity is easy to misjudge by feel alone.

If your reading falls short of the target range, several adjustments help: running a humidifier nearby, placing a bowl of water close to the plant so it evaporates into the surrounding air, standing the pot on a pebble tray filled with water (keeping the pot itself above the waterline so the roots don’t sit in it), positioning the plant in a naturally humid room such as a bathroom or kitchen, or leaving interior doors open so humid air can circulate between rooms.

Misting is sometimes recommended too, and it does raise humidity briefly, but it is worth doing in the morning during warm weather only, since water sitting on the leaves for extended periods increases the risk of fungal disease.

For more on this specific technique, see our guide on misting a monstera for humidity.

Bear in mind that humidity is seasonal. Indoor heating during colder months typically drops relative humidity significantly, so it is worth rechecking your hygrometer reading as the seasons change rather than assuming a spring measurement still holds in winter.

Our guide on caring for a monstera in winter covers the seasonal adjustments in more depth.

3. Your Monstera Needs More Water, or Less

Water is involved in nearly every plant process, from nutrient transport to maintaining the rigidity that holds leaves and stems upright.

Both too little and too much water will slow growth, though the visible signs differ.

Signs of Underwatering

A monstera going short on water typically shows slowed growth, yellowing or browning leaves, drooping (the plant’s way of reducing surface area to cut water loss), leaf drop in more severe cases, and visibly dry soil.

Mild underwatering, where the plant has simply gone a few days too long between waterings, usually shows as slight drooping alone.

More prolonged underwatering brings the fuller set of symptoms, sometimes including a cracked soil surface.

How quickly a monstera dries out depends heavily on its specific conditions.

A plant in a bright south-facing spot in a dry room will need water far more often than one in lower light with higher ambient humidity, so a fixed watering schedule copied from someone else’s setup often doesn’t transfer well to yours.

Getting the Watering Routine Right

Rather than watering on a fixed calendar date, check the soil directly by pushing a finger about two inches in.

If it still feels moist, wait another day or two before checking again; a moisture meter can make this more precise if you would rather not rely on touch.

When you do water, water thoroughly until it runs from the drainage holes, which ensures the whole root zone gets moisture rather than just the surface layer, and adjust the frequency seasonally, since a monstera will need noticeably less water during its winter rest than during active summer growth.

It is also worth checking your potting mix itself.

A mix that drains too fast will dry out the plant before it can take up enough water; if this is a recurring issue, working in more perlite or switching to a mix with better water retention can help considerably.

Equally, too many drainage holes in a pot can cause water to run through faster than the roots can absorb it.

Our guide on building a watering schedule for your monstera goes through this process step by step, and if you’ve already let things go too far, how to revive a dying monstera covers recovery in more detail.

Overwatering Carries Its Own Risk

It is worth being just as cautious in the other direction. Overwatered monstera develop similar-looking yellowing at first, but the underlying cause is root rot rather than dehydration, and by the time mould appears on the soil surface the root damage can already be serious.

If you suspect this is the issue rather than underwatering, our guide on fixing root rot in a monstera explains how to confirm and treat it.

4. Your Monstera Needs More Nutrients

In the wild, a monstera benefits from a constant supply of decomposing leaf litter and organic matter feeding the soil around it, along with effectively unlimited room for its roots to forage further afield when local reserves run low.

A potted monstera has neither luxury. It depends entirely on whatever nutrients are present in its container, and those reserves deplete over time.

Signs of Nutrient Deficiency

An underfed monstera typically shows slowed or stunted growth, smaller leaves than expected, a lack of fenestration in mature plants that should be developing split leaves, and long, weak stems.

Confusingly, over-fertilising can produce some of the same leggy, weak growth, so more feed is not automatically the answer if you are already fertilising regularly.

How to Feed a Monstera Correctly

Monstera deliciosa is not a particularly heavy feeder and often does fine for long stretches without supplemental fertiliser, but a plant that has been in the same pot for a long time and is showing the signs above will usually respond well to a balanced liquid fertiliser, diluted to half the strength recommended on the packaging, applied during watering so the nutrients reach the roots gradually rather than overwhelming them.

Limit feeding to the active growing season, roughly spring through to early autumn, tapering off by mid-autumn so the plant isn’t carrying unused fertiliser into its dormant period.

For full guidance on products and frequency, see our article on the right fertiliser for your monstera.

5. Your Monstera Is in the Wrong Temperature Range

Temperature is easy to overlook because it rarely gets blamed first, yet a monstera kept consistently outside its comfortable range will slow its growth even when light, water, humidity, and feeding are all otherwise correct.

Monstera deliciosa grows best in a fairly wide band, roughly 65°F to 85°F (18°C to 29°C), and tolerates brief excursions either side of that without much trouble.

The problems start with sustained exposure rather than a single cool evening.

Below about 50°F (10°C), growth slows noticeably and the plant can show cold stress symptoms; prolonged exposure to temperatures much lower than that risks lasting damage to leaves and stems.

The Usual Culprit: Drafts, Not the Thermostat

In practice, it is rarely the general room temperature that causes problems, since most homes are kept within a comfortable range for people too.

The more common issue is a specific cold spot the plant happens to be sitting in: a draught from a frequently opened door, a gap around an old window frame, the blast of an air conditioning vent in summer, or a windowsill that gets noticeably colder than the rest of the room overnight.

A monstera in one of these spots can show slowed growth, yellowing, or leaf drop that looks similar to underwatering or low humidity, which is part of why temperature is often missed as the actual cause.

Fixing a Temperature Problem

Move the plant a short distance away from the draught source rather than necessarily out of the room altogether; even a foot or two further from a window or vent often resolves the issue.

Avoid resting the pot directly on cold tile, stone, or concrete flooring, since this can chill the roots even when the surrounding air feels fine, and consider a plant stand or an insulating mat underneath the pot if a cold floor is unavoidable.

During winter, keep the plant away from single-glazed glass overnight, since the glass itself can drop well below room temperature even with the heating on.

6. Your Monstera Is Dormant

As a tropical plant, monstera deliciosa responds to shortening daylight hours and falling temperatures by entering a dormant or semi-dormant state over autumn and winter.

During this period, the plant scales back photosynthesis significantly, since reduced light availability limits how much food it can produce, and growth slows or stops almost entirely as a result.

This is a normal seasonal pattern rather than a sign that something has gone wrong, and it is shared by a great many houseplant species, not just monstera.

What to Do During Dormancy

The instinct to intervene, by feeding or watering more to try to force continued growth, usually backfires.

A dormant plant is not using nutrients or water at its usual rate, so extra fertiliser tends to sit unused in the soil where it can damage the roots, sometimes with effects that only become visible the following spring as distorted or overly soft new growth.

Extra water, similarly, raises the risk of waterlogged soil and root rot rather than encouraging new leaves.

The better approach is to ease off both watering and feeding once dormancy sets in, let the plant rest, and trust that vigorous growth will resume on its own once temperatures and daylight increase again in spring.

7. Your Monstera Has Outgrown Its Pot

This cause is easy to overlook because it develops gradually, but a monstera that has become root bound is one of the most common explanations for growth that has quietly ground to a halt despite otherwise good care.

A root-bound monstera struggles to draw up moisture and nutrients as roots wrap around each other and become restricted, which can cause leaves to wilt, curl, and brown at the edges.

Signs Your Monstera Is Root Bound

The clearest indicator is roots visibly circling the surface of the soil or emerging from the drainage holes at the base of the pot.

Stunted growth despite otherwise correct care is also a strong signal, since monstera are naturally fast growers when given enough root space.

You may also notice water running straight through the pot rather than being absorbed, since a dense, tangled root mass leaves little actual soil left to hold moisture.

Fixing a Root-Bound Monstera

The straightforward fix is to repot into a container roughly two inches larger in diameter, ideally in early spring as the plant enters its main growth period and can recover from the disturbance fastest.

Gently loosen the outer roots before repotting if they have become tightly circled, and refresh the surrounding potting mix at the same time rather than reusing old, depleted soil.

As a general rule, younger monstera benefit from repotting roughly once a year, while mature plants in larger pots can usually go two to three years between repots.

For the full process, see our guide on repotting a monstera, and if you are unsure whether your plant’s pot size is suitable in the first place, choosing the best pot for a monstera is worth reading alongside it.

If Your Monstera Is a New Cutting, Different Rules Apply

Everything above assumes an established plant with a developed root system.

A freshly rooted cutting behaves quite differently, and a lot of “my monstera isn’t growing” questions actually come from people in this earlier stage, expecting leaf growth on a timeline that doesn’t match what is actually happening below the soil.

According to extension research from the University of Minnesota, a propagated monstera node can take up to two to three months before producing its first new leaf, even when rooting has gone well.

During that window, the cutting is putting its energy into establishing roots rather than visible top growth, so the apparent lack of progress is normal rather than a sign of failure.

The clearest way to tell the difference between a cutting that is quietly rooting and one that is actually in trouble is to check the node and any existing roots directly.

Firm, white or pale roots and a node that still looks green or healthy mean the cutting is very likely fine and simply needs more time.

A node that has turned soft, dark, or mushy, or roots that smell unpleasant, point to rot rather than a slow start, and that calls for a fresh cutting rather than more patience.

Whether a cutting was taken from a growing tip or from a leafless internode section also affects what to expect, since each type produces its first new growth from a different point on the stem.

Our full guide on how to propagate a monstera covers cutting selection and aftercare in detail, and if your cutting is a specific variety, propagating monstera Peru walks through that process for that species directly.

Quick Diagnosis Table

UK Reader Note

UK homes present a slightly different set of challenges to the conditions described above, particularly around light and humidity.

Daylight hours are shorter and weaker for much of the year compared with many US regions, so a monstera positioned near an east or south-facing window in the UK may still benefit from a supplementary grow light over autumn and winter, even if it coped fine on natural light alone over summer.

Central heating during the UK winter also tends to drop indoor humidity noticeably, often below the 60% to 80% range monstera prefer, so it is worth rechecking your hygrometer reading once the heating comes on for the season rather than assuming an earlier reading still applies.

Monstera deliciosa is generally rated around RHS hardiness H1B, meaning it needs to be kept indoors or in a heated greenhouse throughout the UK winter rather than left outside, which makes consistent indoor humidity management even more relevant for UK growers than for those in naturally humid climates.

Older UK housing stock with single glazing or draughty original windows is also worth bearing in mind, since a windowsill that feels fine to a person can still drop well below a monstera’s comfortable range overnight in winter.

Pulling the plant a little further into the room during the coldest months is a simple precaution worth taking even if growth has not yet slowed.

Frequently Asked Questions

How fast should a healthy monstera grow?

In good conditions, monstera deliciosa typically grows around two feet per year, though this varies with light, humidity, and the plant’s age and pot size.

Younger plants and those in less than ideal conditions will grow more slowly, which is normal rather than a sign of a problem.

Can a monstera recover after months of no growth?

Yes, in most cases. Once the underlying cause, whether that’s light, humidity, watering, nutrients, dormancy, or pot size, has been corrected, monstera typically resume normal growth within a few weeks to a couple of months, especially if the correction happens at the start of the growing season.

Should I repot my monstera even if it doesn’t look root bound yet?

Routine repotting every two to three years for a mature plant is good preventative practice even without obvious symptoms, since it refreshes depleted soil and gives the roots room before they become genuinely constrained.

Is it normal for a monstera to stop growing completely in winter?

Yes. A near-complete pause in visible growth over autumn and winter is normal dormancy behaviour for this species and does not indicate a problem on its own, provided the plant otherwise looks healthy.

How long should I wait before worrying about a new cutting?

Give a propagated cutting at least two to three months before assuming something is wrong, provided the node and any roots still look healthy.

New leaf growth on a cutting is one of the slower milestones in monstera care, and patience at this stage is usually rewarded rather than wasted.

Could pests be the reason my monstera isn’t growing?

Pests are rarely the primary cause of slow growth, but a plant already weakened by poor light, humidity, or watering becomes considerably more vulnerable to infestation, which can then compound the slowdown.

It is worth checking the undersides of leaves and stem joints for signs of common pests as part of your overall diagnosis.
