Monstera dubia Care Guide

Meet Monstera dubia

Monstera dubia is a fascinating tropical aroid that looks very different from the big, fenestrated Monsteras most people know. Instead of immediately producing huge leaves with dramatic splits, young Monstera dubia grows flat against a surface, with its leaves overlapping like shingles.

This unusual growth habit is what makes it so popular with collectors. Give it a suitable climbing surface and it can create a beautiful living wall of patterned foliage.

And yes, it is a Monstera — it just likes to do things a little differently.

Appearance

Young Monstera dubia produces small, heart-shaped to oval leaves with attractive silvery-green and darker green markings.

The juvenile leaves lie flat against the surface they are climbing, creating the characteristic shingling effect.

As the plant matures and climbs higher, it can eventually transition into much larger foliage. Mature growth may develop fenestrations and a very different appearance from the juvenile plant.

This dramatic change between juvenile and mature growth is one of the most interesting things about Monstera dubia.

Growth Habit

Monstera dubia is a climbing aroid and is particularly well known for its shingling habit.

In nature, the juvenile plant grows tightly against tree trunks and other surfaces. Rather than hanging or sprawling away from its support, it attaches itself closely to the surface and works its way upwards.

This makes it ideal for vertical displays.

Growth Speed

Monstera dubia is generally a moderate grower when given warm temperatures, good humidity, sufficient light and a suitable climbing surface.

It may establish relatively slowly at first, especially after propagation or shipping, but once the root system and climbing growth are established, it can become much more vigorous.

Mature Size

The juvenile plant can remain relatively compact, but mature Monstera dubia can become a substantial climbing plant.

Given enough vertical support, it can climb several metres in suitable conditions.

The size of the leaves increases significantly as the plant matures, so the tiny shingling plant you buy today may have much bigger plans.

Lighting

Bright, indirect light is ideal.

Monstera dubia can tolerate moderate light, but stronger filtered light generally encourages more vigorous growth and helps maintain healthy foliage.

Avoid harsh midday sunlight, particularly through glass, as this can scorch the leaves.

If the plant is kept too dark, growth may become slow and stretched, and the leaves may not develop as strongly.

Watering

Water when the upper portion of the growing medium has dried slightly.

Monstera dubia likes consistent moisture but does not appreciate sitting in constantly saturated soil.

Water thoroughly and allow excess water to drain away completely.

The plant's watering requirements will vary depending on temperature, humidity, pot size, light levels and the type of climbing support being used.

Humidity

High humidity is beneficial.

Aim for approximately 60–80% humidity if practical, especially if you want strong tropical growth and larger leaves.

It can adapt to average household humidity, but very dry air may result in slower growth, crispy edges and increased pest pressure.

Good airflow is still important. Humidity and ventilation need to work together.

Temperature

Warm conditions are ideal.

Aim for approximately 18–30°C, with particularly strong growth occurring when temperatures remain consistently warm.

Protect the plant from cold draughts and prolonged temperatures below approximately 15°C.

Cold conditions combined with wet soil can quickly cause problems.

Soil

Use a chunky, airy and well-draining aroid mix.

A combination of coco coir or quality potting mix, orchid bark, perlite or pumice and other chunky materials works well.

The mix should retain some moisture while allowing plenty of oxygen to reach the roots.

Avoid dense soil that remains wet for long periods.

Fertilising

Feed Monstera dubia during active growth with a balanced, diluted liquid fertiliser approximately every 4–6 weeks.

Regular, moderate feeding can support healthy foliage and climbing growth.

Avoid excessive fertiliser. More food does not automatically mean more leaves, and too much can cause salt accumulation and root damage.

Repotting

Repot when the roots have filled the container or the growing medium has broken down.

Monstera dubia generally does not need an enormous pot. Choose a container only slightly larger than the current root system.

An oversized pot can hold too much moisture and increase the risk of root rot.

Always use a container with adequate drainage.

Pruning

Pruning is mainly useful for controlling the plant's size, removing damaged foliage or taking cuttings for propagation.

If the plant becomes too long, you can cut the stem back to a healthy node.

Do not remove healthy leaves unnecessarily. The foliage is helping the plant build the energy it needs for future growth.

Does Monstera dubia Need a Moss Pole?

Yes — a climbing support is highly recommended.

A moss pole can work very well because it provides a surface for the plant to attach to.

However, Monstera dubia is particularly well suited to flat climbing surfaces because of its natural shingling habit.

A wooden plank, cork bark or another rough vertical surface can produce a very attractive display.

Moss Pole vs Plank

For Monstera dubia, a plank or flat climbing board can be particularly effective.

The juvenile leaves naturally want to lie flat against a surface, so a broad, textured support allows the leaves to shingle naturally.

A moss pole can also work, especially if it provides a sufficiently broad surface, but a narrow pole may not allow the plant to display its characteristic flat growth as effectively.

Cork bark can also be an excellent option for a more naturalistic setup.

How to Encourage Shingling

Give the plant a vertical surface as early as possible.

Position the stem against the support and secure it gently until aerial roots have a chance to attach.

The closer the growing stem remains to the support, the more naturally the leaves can develop in their characteristic overlapping pattern.

Trying to grow Monstera dubia as a hanging plant works against its natural growth habit.

How to Encourage Larger Leaves

Allow the plant to climb and mature.

Bright indirect light, warmth, humidity, adequate nutrition and a healthy root system all contribute to larger foliage.

Most importantly, don't keep chopping the plant back before it has a chance to mature.

Once the plant reaches more mature growth, the leaves can become significantly larger and may begin developing fenestrations.

Mature vs Juvenile Growth

One of the most exciting things about Monstera dubia is the transformation that occurs as it matures.

Juvenile plants produce small, flat, shingling leaves.

As the plant climbs and reaches more mature growth, the leaves can become much larger and eventually develop fenestrations.

The transition does not happen simply because the plant reaches a certain age. Growing conditions and maturity of the climbing stem are important factors.

Winter Care

Growth generally slows during cooler and darker months.

Reduce watering as the growing medium dries more slowly and reduce or stop fertilising if the plant is barely growing.

Keep it warm and in the brightest suitable position.

Avoid cold draughts and sudden temperature changes.

Hydroponics and Semi-Hydro

Monstera dubia can be grown in semi-hydroponic systems such as LECA.

It can also be propagated and rooted in water, perlite or sphagnum moss before being transferred into a more permanent growing medium.

If moving a soil-grown plant into semi-hydro, transition it gradually and allow time for the roots to adapt.

Good oxygenation around the roots remains essential.

Preventing Root Rot

Use an airy growing medium and a pot with drainage holes.

Allow the upper part of the growing medium to dry slightly before watering again.

Avoid leaving the pot sitting in water.

If the soil remains wet for many days, check the drainage, pot size and root condition.

Soft, brown or mushy roots are a warning sign.

After Shipping

Monstera dubia can look a little less impressive after transport, particularly if it has been packed tightly or exposed to changes in humidity and temperature.

Leaves may curl, flatten differently or show minor cosmetic damage.

Give the plant warmth, bright indirect light and suitable humidity and allow it to settle.

Avoid immediately placing it into harsh direct sunlight or making several major changes at once.

Acclimating a New Monstera dubia

If the plant has come from a greenhouse or high-humidity environment, allow it time to adjust.

Place it somewhere bright but protected from harsh direct sunlight.

Keep watering consistent and avoid repeatedly moving the plant while it settles.

New growth is the best sign that the plant has successfully adapted.

Signs Your Monstera dubia Is Happy

Healthy new leaves, active root growth and continued attachment to its climbing surface are all good signs.

Juvenile plants should gradually produce larger, well-formed shingling leaves as they mature.

If the plant is actively climbing and producing healthy new foliage, you are on the right track.

Common Problems

Leaves Not Lying Flat

If the leaves are not shingling against the support, the plant may not be receiving the type of surface it naturally wants to climb.

Try providing a broader, rougher support and securing the stem closer to the surface.

Small Leaves

Some small leaves are completely normal on juvenile plants.

If an established plant suddenly produces much smaller foliage, check light levels, root health, nutrition and climbing conditions.

Yellow Leaves

Yellowing can result from overwatering, poor drainage, root problems, insufficient light or natural leaf ageing.

Check the growing medium before changing your watering routine.

Brown Leaf Edges

Dry air, inconsistent watering, excessive fertiliser or root stress can all contribute to brown edges.

Look at the whole growing environment rather than assuming humidity is the only issue.

Slow Growth

Monstera dubia can naturally be slower when young or when it is establishing a new root system.

Give it warmth, bright filtered light, humidity and a suitable climbing surface before reaching for more fertiliser.

Pests

Monstera dubia can be affected by common aroid pests including spider mites, thrips, mealybugs and scale.

Inspect the undersides of leaves, around nodes and especially fresh new growth.

Spider mites are more likely to become troublesome in warm, dry conditions, while thrips can damage developing leaves.

Regular inspections make pest problems much easier to catch early.

Is Monstera dubia Pet Safe?

No. Monstera dubia, like other Monstera species, contains insoluble calcium oxalates and should not be considered pet-safe.

Chewing or ingesting the plant can cause irritation of the mouth and digestive tract.

Keep it away from pets that like to chew plants.

Is Monstera dubia Safe for Reptiles?

No. Monstera dubia should not be classified as reptile-safe where reptiles may chew or consume the plant.

The presence of insoluble calcium oxalates makes it unsuitable for reptile enclosures where accidental nibbling is possible.

Although Monstera dubia loves warm, humid conditions and can physically thrive in a tropical enclosure, that does not make it safe for reptiles to eat.

Is Monstera dubia Suitable for a Terrarium?

Yes, it can be an excellent plant-only tropical terrarium or plant cabinet specimen, particularly while it is young.

Its shingling growth habit is especially attractive on cork bark, wood or a vertical background.

However, it is not suitable for reptile enclosures because it is not considered reptile-safe.

As it matures, it will also need considerably more vertical space.

Is Monstera dubia Suitable for a Bioactive Vivarium?

From a growing perspective, it can enjoy the warm, humid conditions found in tropical vivariums.

However, because it is not considered reptile-safe, it should not be used in an enclosure where reptiles are able to chew or consume the foliage.

For animal enclosures, choose plants with an established safety record.

Propagation

Monstera dubia is propagated from stem cuttings containing a viable node.

A leaf by itself cannot produce a new plant.

Take a healthy section of stem with at least one node and, ideally, an aerial root.

Cuttings can be rooted in water, sphagnum moss, perlite, soil or semi-hydro media.

Keep the cutting warm, humid and in bright indirect light while roots develop.

Propagation Tip

When taking cuttings, pay attention to the direction of growth.

Because Monstera dubia naturally shinges against a surface, positioning the cutting correctly on its support will help the new growth establish in the right orientation.

A little planning at propagation stage can save a lot of wrestling with the plant later.

Final Care Tips

Monstera dubia is one of those plants that becomes much more interesting once you understand how it wants to grow.

Give it a broad, textured surface to climb, bright filtered light, warmth, humidity, an airy aroid mix and consistent but sensible watering.

The juvenile shingling leaves are already gorgeous, but watching the plant mature and transform into its adult growth is where the real fun begins.

It may start out looking like a tiny leafy tile installation, but give it time — this Monstera has much bigger plans.
