Can You Grow a Monstera in Water Only? A How-To Guide

Growing a monstera in water only is possible and can last indefinitely when done correctly.

The plant is rooted in a container of plain water, with hydroponic nutrients added at every other water change to replace what soil normally provides.

Key variables include light quality, water freshness, and dissolved oxygen levels.

The single most common reason water-grown monsteras fail is using plain water without any nutrient supplement, which leads to slow starvation that looks like a light problem.

If you have tried keeping a monstera cutting in a glass of tap water and watched it slowly lose colour and stop pushing new roots after a few months, you already know the frustrating part nobody tells you upfront: water alone is not enough.

The cutting survives, it even looks healthy for a while, and then something quietly goes wrong. Leaves turn pale. Roots go slimy. New growth stops appearing.

The good news is that growing a monstera in water only is genuinely viable for the long term. People do it for years.

Some of the most impressive monstera setups you will see on plant forums are water-grown plants displayed in large glass vases or clear acrylic containers, showing off enormous root systems.

The difference between those thriving plants and the sad cutting sitting in a forgotten glass of water comes down to a few specific things most beginner guides skip entirely.

This guide covers all of them, from the right way to set up a water-only system to the subtle signs that your monstera is starting to struggle before the damage becomes serious.

If you are new to monstera care generally, the monstera care guide for beginners in small apartments is a good companion read.

Why a Monstera Can Actually Live in Water

Most houseplants would rot quickly if you tried to keep their roots permanently submerged.

Monsteras are different, and understanding why makes everything else about this method easier.

Monstera deliciosa is a semi-epiphyte. In its native Central American rainforest habitat, it starts life on the forest floor and climbs upward toward the canopy, attaching itself to tree trunks with thick aerial roots.

Those aerial roots do not grow in soil. They absorb moisture and dissolved minerals from rain, from humid air, and from organic debris that runs down the bark of trees.

The plant has always been adapted to extracting nutrients from water rather than from a dense soil matrix.

You can read more about this tropical background in the guide to whether Monstera is a tropical plant.

This epiphytic background is why monsteras root so readily in plain water when you take a cutting, and why those roots can survive long-term submersion when given the right conditions.

They are not true aquatic plants, but they are far more tolerant of wet roots than most houseplants because wet roots are essentially what they evolved for.

Water-grown monstera roots look visibly different from soil roots. They tend to be longer, more translucent, and much finer in texture.

You can often see them well enough through a clear glass container to watch them develop over weeks.

This visual access is one of the genuine advantages of growing in water only: root problems become obvious before they become fatal.

What You Need Before You Start

Getting the setup right from the beginning saves a lot of frustration. These are not optional extras.

How to Set Up a Monstera in Water Only

The transition from soil to water is the most stressful part for an established plant. For a new cutting, the setup is more straightforward.

Starting from a Cutting

Take the cutting correctly. Choose a stem section with at least one node, ideally with one or two leaves and a visible aerial root if possible. The full method is covered in the guide to propagating a Monstera.

Cut just below the node using clean scissors or pruning shears.

A dirty cut through diseased material is the most common way to introduce rot from day one.

Remove any soil thoroughly. If you are transitioning from soil, rinse every trace of potting mix off the roots under room-temperature water.

Soil left on water-grown roots creates anaerobic pockets where bacteria thrive and rot begins.

If you are struggling to get your cutting to root at all, the guide to why Monstera cuttings are not rooting covers the most common reasons.

Fill the container with room-temperature water. Cold water shocks roots and slows development. Let tap water sit for at least an hour if you have not filtered it.

Submerge the roots, not the stem. The node and any existing roots should be in the water.

The stem and leaves need to stay above the waterline. A stem that sits permanently submerged will rot, even on a monstera.

Place in bright indirect light. Direct sun through glass heats the water and promotes algae growth as well as leaf scorch.

Wait for rooting before adding nutrients. For new cuttings, give the plant two to three weeks in plain water first.

Adding nutrients before any roots have established can burn the cut end before it has a chance to callus and begin growing.

Transitioning an Established Soil Plant to Water

This is harder, and honest experience says you should think carefully before doing it with a large mature plant.

Smaller plants with younger root systems adapt more readily.

Remove the plant from its pot and rinse off as much soil as possible, then soak the root ball in a bucket of room-temperature water for 15 minutes to loosen what remains.

Check the roots carefully as you clean.

Any roots that are already dark, soft, or smell sour should be trimmed back with clean scissors.

If rot is present, follow the steps in the guide to fixing root rot in a Monstera before placing the plant in water.

Place the cleaned plant in its water container and expect a sulky period of two to four weeks while the existing soil-adapted roots either die back or begin converting to water-adapted growth.

This adjustment period is normal. New root growth emerging after that window is a good sign the plant has settled in.

The Nutrient Problem Nobody Talks About Enough

This is where most water-grown monstera setups quietly fail, and it is worth spending real time on it because the failure mode is deceptive.

When a monstera grows in soil, it draws from a complex system of nutrients including nitrogen, phosphorus, potassium, calcium, magnesium, and a range of micronutrients like iron, manganese, and zinc.

The Monstera fertiliser guide explains the full nutrient picture for soil-grown plants, but water culture changes the equation completely.

Standard houseplant fertilisers cover nitrogen, phosphorus, and potassium, but not the trace elements.

In soil, those trace elements exist naturally in the growing medium. In plain water, there is nothing. The plant will not starve overnight.

It will draw down its internal reserves first, which can take several months. During this time it looks fine, which is why people assume things are going well.

The signs of nutrient depletion in a water-grown monstera are often misread as light problems because the symptoms overlap: pale new growth, smaller leaves with fewer fenestrations, and slower growth overall.

The fix is straightforward. Use a dedicated hydroponic nutrient solution and add it at every other water change rather than every single time.

Over-fertilising in water causes salt build-up on roots that burns them, so erring toward less is always safer than erring toward more.

A quarter of the recommended dose on the label is a good starting point. You can increase gradually if growth remains slow after several weeks.

The aquarium water option is worth highlighting because several experienced growers report excellent results with it.

If you have a healthy freshwater aquarium, using that water for partial changes feeds the monstera gently and naturally.

The fish waste provides ammonia that converts to nitrates, giving the plant a nitrogen source that is kinder to roots than concentrated synthetic fertiliser.

Water Changes: How Often and How to Do It Right

Water changes are the main maintenance task for a water-grown monstera.

Most guides say weekly or fortnightly, which is a reasonable starting point, but the honest answer is that the right frequency depends on your conditions.

The same logic applies to monstera watering in soil, it is always about what the plant needs rather than a fixed calendar.

In summer, in a warm room with good light, the water goes stale faster and the plant drinks more. Weekly changes make sense.

In winter, with reduced light and cooler temperatures, the plant’s metabolic rate drops and the water stays clean longer.

Stretching to every two weeks in winter is fine. The full winter care guide for Monstera covers the seasonal adjustments to expect.

The signs that a change is overdue are easy to read.

The water will start to look slightly murky or greenish, the container may develop an algae film on the sides, and you might notice the roots beginning to look slightly slimy.

Fresh water should be clear and the roots should look crisp.

Light Requirements for a Water-Grown Monstera

Light requirements for a water-grown monstera are essentially the same as for a soil-grown one.

The full Monstera light requirements guide covers placement and orientation in detail, but there is one important additional consideration for water culture: direct sun on a clear water container accelerates algae growth and can heat the water to temperatures that stress or damage roots.

Bright, indirect light is the target. In practical terms, that means a spot within three to four feet of a window that does not receive direct sun rays for more than an hour or two during the early morning. A guide to where to place your Monstera gives room-by-room placement advice.

East-facing positions are ideal for this reason.

North-facing spots work but tend to produce slower growth, less fenestration on new leaves, and a leggier plant over time.

A monstera in a genuinely dark corner will technically survive in water, but it will not grow in any meaningful way.

The leaves that do emerge will be smaller, paler, and may have minimal or no splits. This is a light and energy problem, not a water problem, and no amount of nutrient adjustment will fix it.

If your best available spot is low light, a full-spectrum grow light set to run for 12 to 14 hours per day makes an enormous practical difference.

The guide to the best grow lights for Monstera covers specific product recommendations at different price points.

It does not need to be expensive: a basic LED grow strip set up to provide top or side lighting is enough to keep the plant actively growing through a dark winter.

Temperature and Humidity

Monsteras in water need the same warmth as soil-grown plants: temperatures between 18 and 29 degrees Celsius are the comfortable range.

Below 15 degrees Celsius, root activity slows to near zero.

A cold windowsill in winter, particularly one with draughts through the frame, can drop root temperature significantly even if the air temperature in the room feels fine.

A simple fix is to place the container on a folded cloth or cork mat, which creates a small layer of insulation between the cold glass or sill surface and the base of the container.

Humidity is less critical for water-grown plants than for soil-grown ones because the roots are never short of moisture.

You can read about the ideal humidity levels for Monstera if you want the full picture.

However, aerial roots left dangling in dry air will desiccate and shrivel at the tips.

If you want those aerial roots to develop and contribute to the plant’s nutrient uptake, a spot with naturally higher humidity or a pebble tray near the plant helps.

Misting the plant can also provide short-term relief for aerial roots in dry air, though its effect on ambient humidity is limited.

Troubleshooting Water-Grown Monsteras

Roots Turning Brown and Slimy

This is the most urgent issue and the one that catches people out because it can develop quickly.

Brown, soft, slimy roots mean the water has been too warm, too stagnant, or that pathogens have established.

Remove the plant, trim all affected roots back to healthy pale tissue, rinse the container thoroughly, and return the plant to fresh water.

If more than half the root system is affected, the plant is fighting for survival and recovery is not guaranteed.

Prevention is straightforward: regular water changes, keeping the container out of direct sun, and never letting the water go weeks without being refreshed.

Yellowing Leaves

In a water-grown monstera, yellowing leaves have three common causes: nutrient deficiency, insufficient light, or the natural ageing of older lower leaves.

Nutrient deficiency tends to show up first as pale, washed-out new growth and interveinal chlorosis on younger leaves, where the veins remain green but the tissue between them yellows.

This pattern is a classic indicator of magnesium or iron shortage, both of which are absent from plain water.

Adding a hydroponic nutrient that includes trace elements usually reverses this within a few weeks.

Light deficiency yellowing tends to affect the plant more evenly and produces leggy growth between leaves.

If the newest leaves are very small and barely fenestrated, the problem is almost certainly light rather than nutrients.

See the full guide to why Monstera leaves are not splitting for the complete explanation.

A single older leaf going yellow at the base of the plant is usually just natural shedding and not a cause for concern.

Multiple leaves yellowing at the same time, particularly on newer growth, is a signal worth investigating.

No New Growth for Weeks

A monstera that has settled into a water-only setup should produce new leaves during the growing season.

If it stops entirely and the roots look healthy, the most likely causes are insufficient light and low temperature.

The guide to why Monstera is not growing helps distinguish between the common causes.

Check that the root zone is not sitting on a cold surface and that the plant is getting adequate light.

In winter, slow or stopped growth is normal and does not require intervention.

Stem Rotting at the Waterline

This is a specific failure mode that happens when the stem sits at or below the waterline rather than above it.

The fix is to raise the plant so that only the roots and the node are submerged, with the stem clear of the water surface.

Pebbles placed in the bottom of the container to prop the plant at the right height are a practical solution.

Can a Monstera Live in Water Only Forever?

The honest answer is: probably, with the right maintenance, but expect some trade-offs compared to a soil-grown plant.

Long-term water-grown monsteras tend to grow more slowly than soil-grown ones.

A well-fed soil plant in good light will outpace a water-grown counterpart on leaf production and overall size.

If maximising leaf production is the priority, the guide to getting a Monstera to grow more leaves covers the conditions that drive the fastest growth in soil culture.

This is partly because water culture cannot fully replicate the complex biological activity of a healthy soil ecosystem, which includes mycorrhizal fungi, beneficial bacteria, and a structured nutrient matrix that soil provides naturally.

That said, water-grown monsteras can live for many years and produce large, healthy, fenestrated leaves consistently when the conditions are right.

The constraint is almost always nutrients and light.

Get those two things right and the water method is genuinely viable as a permanent setup rather than just a propagation stage.

One thing worth knowing: once a monstera has been growing in water for more than a few months, transitioning it back to soil becomes harder.

The water-adapted roots are poorly equipped for soil conditions and the plant often goes through a stressful adjustment period that can take months.

If you do need to revive a plant that has suffered in water culture, the guide to reviving a dying Monstera covers recovery from a range of different problems.

If you commit to water culture, it is easier to stay in it than to switch back and forth.

Monstera Adansonii in Water vs. Monstera Deliciosa

Monstera adansonii adapts to water culture even more readily than Monstera deliciosa.

Its roots are finer, it roots faster from cuttings, and it tends to be more forgiving of the occasional missed water change.

You can see how it compares as a trailing plant in the Monstera adansonii hanging guide.

If you are new to the water-growing method and want to practise on something lower stakes before committing a large deliciosa to a glass vase, adansonii is a good starting point.

Monstera deliciosa variegated forms such as Thai Constellation and Albo Variegata can be grown in water but need extra attention to nutrients.

These are among the rarest Monstera varieties and also among the most expensive, one of the reasons some Monsteras are so expensive is the difficulty of propagating variegated forms reliably.

The white or yellow variegated sections of leaves contain less chlorophyll and the plant produces less energy from light overall, meaning any nutrient shortage shows up faster and more severely than in a standard green plant.

For a broader look at species that might suit water culture, the full Monstera varieties guide covers the range of plants within the genus.

Frequently Asked Questions

Can a monstera really grow in water only, or does it need soil eventually?

A monstera can grow in water only as a permanent setup, not just as a temporary propagation stage.

The plant adapts by producing water-specific roots that extract nutrients and oxygen from the water rather than from soil.

The critical requirement is a hydroponic nutrient solution added regularly, because plain water does not contain the nitrogen, trace minerals, or micronutrients the plant needs to sustain itself.

With the right nutrients and adequate light, a water-grown monstera can live and continue pushing out new leaves for years.

How often should I change the water for a monstera growing in water?

Change the water every one to two weeks as a general guideline, adjusting based on season and conditions.

In summer with warm temperatures and active growth, weekly changes keep the water fresh and the roots healthy.

In winter when growth slows and temperatures drop, fortnightly changes are usually fine.

The practical signs that a change is due are murky or greenish water, a slight sour smell, or roots beginning to feel slippery.

Always use room-temperature water rather than cold to avoid shocking the root system.

What fertiliser should I use for a monstera in water only?

Use a dedicated hydroponic nutrient solution rather than standard houseplant fertiliser.

The reason is that soil contains trace elements like iron, manganese, calcium, and magnesium that a standard NPK fertiliser does not include.

In a water-only system, those trace elements must come from the nutrient solution itself.

Brands such as General Hydroponics Flora Series, MaxiGro, and similar products are formulated specifically for water culture and contain the complete nutrient profile a monstera needs.

Start at one-quarter of the recommended dose and increase gradually only if growth remains slow after several weeks at that level.

Why are my water-grown monstera’s leaves turning yellow?

In a water-grown monstera, leaf yellowing has three main causes. Nutrient deficiency is the most common in this setup. It tends to produce pale new growth and yellowing between the leaf veins on younger leaves.

The full guide to why Monstera leaves turn yellow covers each cause and how to distinguish between them.

Insufficient light produces more even yellowing across the plant and noticeably leggy growth.

Natural ageing accounts for the occasional single older leaf going yellow at the base of the plant, which is not a problem.

If multiple leaves yellow at once or the newest growth comes in pale, investigate nutrients and light before assuming anything else is wrong.

Can I use tap water for a monstera in water only?

Most tap water is fine for a water-grown monstera, particularly if you leave it to sit overnight before using it.

Leaving it out allows chlorine to dissipate, which is the primary concern with tap water and plant roots.

Hard tap water with high mineral content is a more significant issue for long-term water culture because the dissolved minerals accumulate on roots over time and can interfere with nutrient uptake.

If your tap water is very hard and you notice white deposits forming on the roots or container walls, switching to filtered water or collecting rainwater is worth the effort.

Will a monstera grow faster in water or soil?

Soil almost always produces faster growth than water culture when both are set up well.

Healthy soil contains a complex biological ecosystem including mycorrhizal fungi and beneficial bacteria that assist nutrient uptake in ways that water culture cannot replicate.

If you want to compare approaches, the guide to growing Monstera using hydroponics covers LECA and other substrate options that sit between pure water and soil.

A well-maintained soil-grown monstera in good light will produce more leaves per year and reach a larger size than an equivalent water-grown plant.

The trade-off is that water culture offers easier root monitoring, no soil mess, and a striking visual display of the root system.

If maximum growth speed is the goal, soil is the better medium. If aesthetics and ease of root inspection matter more, water is a genuinely viable alternative.

How do I stop algae growing in my monstera water container?

Algae grow in water when light and nutrients are both present.

Switching to a dark or opaque container eliminates the problem almost entirely because algae cannot photosynthesise without light.

If you want to keep a clear container for root viewing, move it out of any direct sun and clean the container walls with a soft brush at every water change.

A very small amount of 3 percent hydrogen peroxide added to fresh water (around 1ml per litre) creates an oxygen-rich environment that suppresses algae without harming the roots.

This is not necessary as a standard routine, but it is useful if algae keep returning despite regular cleaning.

Can I transfer a soil-grown monstera to water?

You can, but it is not without risk, and the plant will go through an adjustment period that can last several weeks.

The main challenge is that roots developed in soil are structurally different from water-adapted roots.

When moved to water, many soil roots will gradually die back and new water-adapted roots will grow in their place.

During this transition the plant may drop some leaves and look generally unhappy.

Smaller plants with younger root systems adapt more successfully than large established specimens.

Make sure to check your soil type and root condition before the transition, healthy soil roots give the plant a better chance of adapting successfully.

If you want to try the transition, clean off all soil thoroughly before placing the plant in water, watch the roots closely for signs of rot, and be patient with the adjustment period.

Key Takeaways

• Use hydroponic nutrient solution at every other water change. Plain water is not enough for long-term water culture and will lead to slow nutrient starvation that is often misread as a light problem.
• Keep the stem above the waterline at all times. Only roots and the node should be submerged. A stem sitting in water will rot.
• Change the water every one to two weeks and rinse the container at the same time. Stagnant water is the primary cause of root rot in water-grown monsteras.
• Place the container in bright, indirect light, not direct sun. Direct sun heats the water and promotes algae while risking leaf scorch.
• Use room-temperature water. Cold water shocks the roots and slows growth.
• Start nutrients at one-quarter the recommended dose on the label. Over-fertilising burns roots faster than under-fertilising weakens them.
• Check roots at every water change. Pale cream, firm, and slightly translucent roots are healthy. Dark, soft, or slimy roots need immediate attention.
• If committing to water culture long-term, stay in it. Transitioning back to soil after extended water growth is stressful for the plant and often results in months of slow recovery.

Final Thoughts

If you came to this article because a cutting in a glass of water stopped looking healthy after a few months and you could not work out why, you now have the reason.

Plain water runs out of what a monstera needs to sustain itself, and that slow depletion looks deceptively like a light problem right up until the leaves start going pale.

The water-only method genuinely works when you treat the nutrient question seriously.

A well-nourished monstera in a clear glass container, roots visible and white, pushing out a new fenestrated leaf every few weeks, is one of the more satisfying things you can have on a windowsill.

It is also a setup that gets you in the habit of checking your plant regularly, which is the single best thing you can do for any houseplant regardless of growing method.

Start simple: a healthy cutting, a clean clear container, filtered or overnight tap water, and a small bottle of hydroponic nutrients.

The rest you can adjust as you go based on what the plant tells you.
