How to Propagate a Swiss Cheese Monstera

Propagating a Swiss cheese Monstera (Monstera deliciosa) comes down to one essential move: cutting a section of stem that includes at least one node and rooting it in water or soil. The node is where the plant’s aerial roots and new growth emerge, and without one, a cutting will never develop roots no matter how healthy the leaf looks. The process is straightforward enough that it has become one of the most popular houseplant projects worldwide, but a few details separate a cutting that thrives from one that rots in a jar.

Why Monstera Is Built to Be Propagated

Monstera deliciosa is a hemiepiphyte, meaning it spends part of its life growing on other plants rather than rooted exclusively in the ground. In the wild, a Monstera seed germinates on the forest floor, grows toward the nearest tree trunk, and begins climbing. As it ascends, it sends out two distinct types of aerial roots: anchoring roots that grip the host tree for mechanical support, and feeder roots that reach down toward the soil to absorb water and nutrients. Research on the closely related Monstera acuminata found that these feeder roots compensate for the plant’s lack of secondary growth by providing hydraulic conductivity the main stem cannot achieve on its own.¹ This ability to produce adventitious roots from stems and nodes is hardwired into the genus. When you take a cutting and place it in water, you are exploiting a survival strategy the plant already uses in the jungle.

Finding the Node

The node is a slightly thickened ring or bump on the stem where a leaf petiole meets the main vine. On a mature Monstera, it often has a visible brownish nub or a small aerial root already starting to poke out. Each node is a point of concentrated meristematic tissue, the cells capable of differentiating into roots, shoots, or new leaves. A cutting without a node is just a leaf on a stick: it can survive in water for weeks, looking deceptively alive, but it will never root or produce new growth.

The easiest way to identify a good cutting site is to look for a node that already has a small aerial root. That aerial root gives the cutting a head start. If no aerial root is present, you still want at least one node and ideally one healthy leaf above it. The leaf will continue photosynthesizing and feeding the cutting energy it needs to push out roots.

How to Take the Cutting

Use a clean, sharp blade. A dull knife crushes stem tissue, which invites bacterial and fungal infection. Sterilize with rubbing alcohol or a flame before making your cut. Cut about an inch below the node and an inch or two above it. If you are dividing a long vine into multiple cuttings, each segment should have at least one node and one leaf. Two nodes per cutting gives you a backup if one fails.

Let the cut end dry for 30 minutes to an hour before placing it in water or soil. This brief callusing period allows the wound to seal slightly, reducing the chance of rot. Some growers skip this step and root successfully, but it costs almost nothing in time and adds a layer of insurance.

Water Propagation

Water rooting is the most popular method because you can watch the roots develop in real time. Place the cutting in a glass or jar so the node and any aerial root nubs are submerged, but the leaf stays above the waterline. A few practical details matter more than people realize:

• Water quality: Tap water is fine for most areas, but if your municipal supply is heavily chlorinated, let a jar sit out overnight so the chlorine off-gasses. Room-temperature water is better than cold, which can shock the cutting.
• Water changes: Swap the water every three to five days. Stagnant water depletes dissolved oxygen and becomes a breeding ground for bacteria. If the water turns cloudy or starts to smell, change it immediately.
• Container choice: A clear container lets you monitor root growth. Avoid containers with narrow necks that will trap roots later when you transplant.
• Light: Bright, indirect light is ideal. Direct sun on a glass of water can heat it to levels that cook tender new roots and promote algae growth. A spot a few feet from a bright window works well.

You should see small white root tips within one to three weeks, depending on temperature and the health of the cutting. Wait until roots are at least two to three inches long before transplanting to soil. Roots that are too short may not survive the transition.

Soil Propagation

Rooting directly in soil skips the transplant shock that sometimes stalls water-rooted cuttings. The tradeoff is that you cannot see what is happening below the surface, and there is a slightly higher risk of rot if the soil stays too wet.

Use a chunky, well-draining mix. A blend of potting soil, perlite, and orchid bark in roughly equal parts gives the cutting both moisture retention and air pockets. Insert the cutting so the node is buried about an inch deep. Water the soil lightly and keep it consistently moist but not waterlogged. A good test: if you squeeze a handful and water drips freely, the mix is too wet.

Covering the pot with a clear plastic bag or placing it in a propagation box raises humidity around the cutting, which helps in the critical first two weeks. You can tug gently on the cutting after about three weeks. If you feel resistance, roots have formed.

Air Layering for a Headstart

Air layering lets you root a section of the vine while it is still attached to the mother plant, meaning the cutting never has to survive on stored energy alone. Wrap damp sphagnum moss around a node that has an aerial root nub, then wrap plastic film around the moss to hold moisture in. Secure both ends with twist ties or tape. Keep the moss damp by misting through a small opening every few days.

After three to six weeks, you should see roots growing through the moss. At that point, cut below the rooted section and pot it up. Air layering is especially useful for large, mature plants where you want to propagate a top cutting without risking an expensive or sentimental specimen. The cutting transitions to independence with a functioning root system already in place.

What Happens Inside a Cutting

When you sever a stem from the mother plant, the cutting loses its supply of water, nutrients, and certain hormones that the root system was delivering. At the same time, auxin, a hormone that normally flows downward through the plant, begins accumulating above the cut site because it no longer has anywhere to go.² That buildup of auxin at the base of the cutting is one of the key signals that triggers adventitious root formation. The cutting is essentially redirecting its hormonal traffic into a survival response.

This is why a node is non-negotiable. Nodes contain the meristematic cells that can respond to that auxin signal and begin dividing into root tissue. An internode section of bare stem lacks those cells and cannot respond, regardless of hormone levels. The leaf above the cut, meanwhile, keeps photosynthesizing and shipping sugars downward to fuel root growth, which is why keeping at least one healthy leaf on a cutting matters so much.

Whether to Use Rooting Hormone

Monstera is vigorous enough that most cuttings root without any hormone treatment. But rooting hormone can speed things up, particularly for cuttings with no pre-existing aerial root or for varieties that tend to root more slowly. The active ingredient in most commercial rooting powders and gels is indole-3-butyric acid (IBA), a synthetic auxin. Studies on stem cuttings treated with IBA have found that it dramatically increases both the number and length of roots compared to untreated controls, with one study reporting roots more than five times longer than untreated cuttings at higher concentrations.³

If you decide to use it, dip the cut end (where the node is) into rooting powder or gel before placing it in soil. For water propagation, rooting hormone is less commonly used because it washes off quickly, though some growers add a small amount of liquid rooting concentrate to the water. Honestly, for a standard green Monstera deliciosa, the plant’s own auxin response is usually enough. Rooting hormone becomes more valuable for variegated cuttings or cuttings taken from less vigorous parts of the plant.

Why Humidity Matters More Than You Think

A cutting without roots has no way to pull water from the soil or medium in the normal way. It relies on moisture absorbed through its stem tissue and on whatever water the leaf can take in from humid air. Research on leafy cuttings placed in a high-humidity fog environment found that stomatal conductance in young, expanding leaves increased almost tenfold over the first 14 days, and that cuttings maintained much higher leaf water potential than leaves on the intact mother plant before any visible roots had even formed.⁴ In plain terms, the cutting’s leaves opened up their stomata wide in the humid environment, staying hydrated even without roots.

For home propagation, you do not need a fog system. A clear plastic bag over the pot, a propagation box with a lid, or even a large clear storage bin turned upside down creates a humid microclimate. Misting the inside of the cover every couple of days keeps humidity high. The goal is to reduce water loss from the leaf so the cutting can channel its energy into root production instead of fighting dehydration. Once roots are a couple of inches long, you can gradually open the enclosure to acclimate the cutting to normal room humidity.

Temperature and Timing

Monstera cuttings root fastest in warm conditions, roughly 65 to 80°F (18 to 27°C). Below 60°F, metabolic activity slows and rooting can stall for weeks. Above 85°F, the risk of bacterial growth in water and rot in soil climbs quickly. Room temperature in a typical home is usually in the sweet spot.

Spring and early summer are the best times to propagate because the plant is entering its active growth phase. Cuttings taken in winter, when the plant’s metabolism naturally slows, root more slowly and are more prone to failure. If you must propagate in winter, provide supplemental warmth with a heat mat placed under the container, keeping the root zone a few degrees warmer than the surrounding air.

Propagating Variegated Monstera

Variegated cultivars like Monstera deliciosa ‘Albo-Variegata’ and ‘Thai Constellation’ are propagated the same way, but the stakes are higher and the margin for error is thinner. The white or cream-colored portions of a variegated leaf lack chlorophyll and produce no energy through photosynthesis. A cutting that happens to have mostly white tissue will struggle to power root growth because the remaining green tissue may not produce enough sugar.

When choosing a cutting from a variegated plant, pick one with a good balance of green and white on the leaf, leaning toward more green. An all-white or heavily white cutting looks dramatic but frequently fails. Some growers specifically look for cuttings where the node itself has some green coloring, since the new growth emerging from that node is more likely to produce functional green leaves.

Variegated Monstera also grows more slowly in general because it has less photosynthetic tissue. Expect rooting to take longer, sometimes four to six weeks in water before you see substantial root development. This is where rooting hormone and a humid enclosure become more worthwhile investments rather than optional extras.

Common Mistakes

The most frequent propagation failure is rot, and it almost always comes down to one of a few errors:

• No node on the cutting: A single leaf with a petiole but no stem node will not root. It may stay green in water for a surprisingly long time, which fools people into thinking it is working.
• Too much water in soil: A waterlogged propagation mix suffocates the developing root cells. Drainage holes and a chunky mix are not optional.
• Dirty water: Bacterial buildup in unchanged water turns the stem mushy. If the submerged portion of the stem starts turning brown or soft, trim the damaged tissue, let the cutting dry, and start with fresh water.
• Too much direct sun: Strong direct sunlight heats the water, stresses the unrooted cutting, and promotes algae. Bright indirect light is the target.
• Transplanting too early: Moving a water-rooted cutting to soil before roots are at least two inches long often leads to the cutting wilting and dying. The root system needs enough mass to sustain the leaf once it loses the constant water supply.

Transitioning Water Roots to Soil

Roots that develop in water are structurally different from roots that develop in soil. Water roots tend to be more delicate, with thinner cell walls adapted to an aquatic environment. When you transplant a water-rooted cutting into soil, those roots need time to adapt. The cutting often looks a bit droopy for the first week or two as the roots adjust.

To ease the transition, keep the soil consistently moist for the first two weeks after planting, more so than you would for an established Monstera. Some growers gradually add soil to the water over a period of days to create an intermediate environment, though this is more fiddly than most people need. The simpler approach is to pot the cutting in a well-draining mix, water thoroughly, and keep humidity high with a bag or propagation box for the first week. After that, gradually reduce watering frequency to the normal schedule for an established plant.

From Cutting to Climbing

Once your propagated Monstera has settled into its pot and started pushing out new leaves, you will notice something: the leaves stay relatively small and may lack the dramatic splits and holes the plant is famous for. Fenestrations, the Swiss cheese holes, develop primarily on mature leaves produced by a climbing plant that receives adequate light. A young cutting growing in a pot on a shelf may produce solid, unfenestrated leaves for months or even years.

Giving the plant a moss pole, coco coir pole, or trellis to climb triggers the developmental shift toward larger, more fenestrated leaves. The plant detects vertical support through its aerial roots, which is part of the same hemiepiphytic program that makes Monstera so easy to propagate in the first place. The anchoring roots grip the pole, and the plant responds by producing bigger internodes and more elaborate leaf architecture. If you propagated your Monstera specifically because you love those iconic perforated leaves, getting it onto a support structure and into bright indirect light is the fastest path there.
