A large Monstera deliciosa can dominate a room, and taking a stem cutting is a useful way to make a second plant while reducing an unruly vine. The important point is that a cutting needs a node. One beautiful split leaf with a long stalk may look convincing in a vase, but without suitable stem tissue and a growing point it will not produce a normal new plant.
Monstera are climbers, and their aerial roots and knobbly nodes are easy to identify once you look closely. Take time to plan a cut rather than cutting the first leaf that reaches the ceiling.
Find a node before you pick up scissors
Look along the main stem for the junction where a leaf stalk attaches. This is the area containing the node, from which new roots and shoots can develop. Aerial roots may also be growing nearby, sometimes as thick brown cords.
A cutting with a healthy node and at least one suitable leaf is a practical starting point. A section carrying an existing aerial root may be convenient, but an aerial root alone without the correct stem and node is not a substitute for viable cutting material.
Remember that Monstera deliciosa and Monstera adansonii have different-sized leaves and growth habits. Both can be propagated by stem cuttings, but the finished plants may need different support and space.
Take cuttings when the plant is growing
Spring and summer generally offer warmth and sufficient light for new roots to form. Monstera tolerates ordinary warm room conditions, but a cold windowsill in midwinter can slow rooting dramatically.
Choose a healthy section free from visible pests, mushy areas or severe yellowing. Use clean, sharp secateurs suitable for the stem thickness. Wipe the tools before moving between plants, particularly if you've been cutting diseased material.
Wear gloves if sensitive to sap. The RHS identifies Monstera as harmful if eaten and potentially irritating to skin and eyes. Keep cuttings and trimmings away from pets and young children.
Make a cut that includes living stem
Trace the vine down from the chosen leaf until you find its node. Cut below that node, allowing enough stem to stand securely in a jar or pot. Avoid slicing through a viable node just to make the cutting shorter.
If an aerial root is already attached to the section, handle it gently. Don't attempt to force a thick, stiff root around a narrow jar opening; choose a suitable vessel or carefully direct the cutting into a propagation pot.
A large leaf can lose water while the cutting has no functioning roots. You may need to choose a modestly sized shoot rather than the most enormous leaf on the parent plant.
Root a monstera cutting in water
Use a clean jar with enough water to cover the lower node while keeping the leaf and most of its stalk above the surface. Position the cutting where it receives bright but indirect light.
Check the water and refresh it when cloudy. Roots may grow from the submerged node and nearby stem tissue. Avoid allowing decaying leaf material to remain in the jar.
There is no single reliable countdown for rooting. Temperature, light, season and the health of the cutting matter. Wait for a practical root system, not just one fine root you can barely see.
Root directly into a suitable potting medium
A small pot of airy, free-draining peat-free propagation compost is an alternative to water. Make a hole for the stem, place the node into the medium and firm gently, leaving leaves above the surface.
Moisten the medium and allow excess water to drain. Keep the plant warm with bright indirect light. A humidity cover may help in a very dry room, but trapped condensation and soggy compost increase the risk of rot.
Avoid a giant pot. When only a small cutting is present, a large volume of wet compost may remain damp far longer than the new roots can use it.
When should the cutting be potted up?
Water-rooted cuttings can move into potting compost once they have several healthy roots capable of supporting the plant. Handle them carefully as new roots are vulnerable to snapping.
Choose a small pot with drainage holes and a loose mix suited to aroid houseplants. Set the node and roots into the compost without burying the entire leaf stalk. Water to settle the mix and let it drain.
The transition from water to compost may require extra attention for the first few weeks. Keep the medium suitably moist but not saturated, and avoid applying heavy fertiliser to a plant that is still establishing.
What happens to the parent plant?
After a cut, the original Monstera can activate growing points lower on its remaining stem and produce new shoots. Whether it does so quickly depends on light, season and vigour.
Don't strip a weak plant of every leaf to make cuttings. Leave enough healthy growth to support recovery. If the plant was leaning because its pole had failed, improve the support as well as shortening selected stems.
Monstera climbs in nature and often develops larger, more deeply split leaves when given appropriate light and support. A newly rooted cutting with small unsplit leaves is not necessarily inferior; it is going through an earlier growth stage.
Propagating a variegated Monstera
Variegated cultivars are often expensive, which makes guessing where to cut a bad idea. Examine the stem as well as the leaves. A leaf with plenty of white doesn't guarantee the next shoot will have the same pattern.
New growth comes from a viable bud at the node. If you cannot identify a healthy node and likely growth point, wait and research that exact cultivar's propagation requirements before cutting.
Keep the plant in appropriate light while avoiding harsh direct sun. Very pale sections can have less chlorophyll and may be more prone to stress. Take fewer well-planned cuttings rather than dividing an expensive plant into numerous uncertain pieces.
Troubleshooting yellow leaves and rotting stems
A cutting turning soft and dark at the submerged section may be rotting. Remove damaged material with clean tools if healthy stem and a viable node remain, replace contaminated water or compost and reduce excessive moisture.
Yellowing after transplanting can reflect stress, poor drainage or loss of damaged roots. Check the actual moisture level. A wet pot is not improved by further watering.
If a large leaf remains healthy but never produces a shoot, double-check that the cutting includes a node and growing point. A leaf without the correct stem tissue can remain attractive for a time without becoming a new plant.
Give the young Monstera space to grow
Once established, position the pot in warm, bright indirect light and provide support if you want a climbing habit. Turn the pot carefully as needed to avoid severe leaning towards the window.
Monitor moisture with your finger rather than a strict calendar. Water properly and allow excess to drain, then let the compost approach drying before watering again according to conditions.
The goal of propagation is a healthy new plant, not just a jar full of decorative leaves. A clean cut below the correct node and sensible aftercare will do most of the work.
