How to Propagate Monstera: Stem Cuttings and Air Layering

Monstera deliciosa — the iconic Swiss Cheese Plant — is one of the most popular houseplants to propagate, and for good reason. A single healthy cutting can grow into a full, fenestrated specimen within a year or two. Plus, Monstera cuttings with aerial roots look spectacular rooting in a clear vase.

This guide covers 3 methods: stem cuttings in water, stem cuttings in soil, and air layering (the most advanced but most reliable method for large plants).

Understanding Monstera Anatomy

Successful Monstera propagation starts with knowing where to cut. Take a moment to examine your plant and identify these parts:

Nodes

A node is the slightly thickened ring on the stem where a leaf petiole (the long stalk connecting the leaf to the main stem) attaches. It usually looks like a brownish or lighter-colored ring or bump on the stem. This is where new roots and growth will emerge from your cutting. No node = no new plant.

Aerial Roots

Monstera plants produce thick, brown, woody roots that grow out from nodes into the air. In the wild, these anchor the plant to trees as it climbs. For propagation, aerial roots are a huge advantage — they often start absorbing water immediately when submerged, giving your cutting a head start on rooting.

Internodes

The smooth sections of stem between nodes. There is no meristem tissue here, so cuttings without a node will not produce new growth no matter how long you wait.

Method 1: Stem Cutting in Water

This is the most popular Monstera propagation method. A cutting with a big aerial root sitting in a clear glass vase is honestly one of the most beautiful things in indoor gardening.

Step-by-Step

1. Choose your cutting. Identify a section of stem with at least one node, one leaf, and ideally one aerial root. A cutting with 1-2 leaves is ideal — more leaves means more energy demand on a rootless cutting.
2. Make the cut. Using clean, sharp pruning shears or a serrated knife, cut the stem about 1-2 inches below the node. If the stem is thick and woody, a serrated blade works better than scissors.
3. Trim if needed. If the aerial root is extremely long (over 12 inches), you can trim it to about 6 inches. If the cutting has more than 2 leaves, consider removing one to reduce water demand while roots establish.
4. Place in water. Submerge the node and aerial root in a vessel of room-temperature water. The leaf and petiole must stay above water. Use a vase or jar wide enough to accommodate the aerial root without cramming it.
5. Bright indirect light. Place near a bright window but out of direct sun. Direct sun heats the water and encourages algae.
6. Change water weekly. Fresh water provides dissolved oxygen and prevents bacterial rot. If the water gets cloudy before a week, change it sooner.
7. Roots appear in 2-4 weeks. If your cutting had an aerial root, new white water roots often emerge from it within 2 weeks. Cuttings without aerial roots take closer to 4-6 weeks.
8. Transfer to soil at 3-4 inches of root length. Once roots are well-established and 3-4 inches long, transition to soil.

Method 2: Stem Cutting in Soil

Soil propagation produces stronger, soil-adapted roots and eliminates the risky water-to-soil transition. It requires slightly more attention to moisture levels but delivers a more robust plant.

Step-by-Step

1. Take your cutting the same way as the water method.
2. Let it callous (optional). Some propagators let the cut end dry for a few hours. This is not strictly necessary for Monstera but can reduce rot risk in heavy soils.
3. Prepare a chunky mix. Monstera roots need air. Use a mix of potting soil, perlite, and orchid bark in roughly equal parts. This provides moisture retention, drainage, and airflow simultaneously.
4. Plant the cutting. Bury the node 2-3 inches deep. If there is an aerial root, bury it too — it will develop water-absorbing root hairs in soil. Firm the soil gently around the stem.
5. Water thoroughly. Soak the soil until water runs out the drainage holes. Then allow the top 2 inches to dry before watering again.
6. Create humidity. Place a clear plastic bag loosely over the cutting (not touching the leaf) to create a humidity dome. Remove daily for 30 minutes to prevent mold. Alternatively, place the pot near a humidifier.
7. Roots establish in 4-6 weeks. The cutting will produce new growth (an unfurling leaf) once roots are established enough to support it. This is your confirmation of success.

Method 3: Air Layering

Air layering is the most reliable propagation method because the cutting develops roots while still attached to the mother plant. It is getting nourishment from the parent the entire time it is rooting, virtually eliminating the risk of the cutting dying before it roots.

What You Need

• Long-fiber sphagnum moss
• Plastic wrap (cling film)
• Twist ties, string, or tape
• A sharp, clean knife

Step-by-Step

1. Choose a node. Pick a node on the stem where you want to eventually make your cut. Nodes with existing aerial roots are ideal.
2. Make a small notch (optional). Using a clean knife, make a small upward-angled cut about one-third of the way through the stem, just below the node. This wound encourages the plant to send rooting hormones to that area. Skip this step if it makes you nervous — it works without the notch too, just a bit slower.
3. Soak sphagnum moss. Hydrate a generous handful of sphagnum moss until it is thoroughly wet, then squeeze out excess water.
4. Wrap the node. Pack the moist sphagnum moss around the node (and any aerial root present), forming a ball roughly the size of a tennis ball.
5. Wrap with plastic. Wrap the moss ball tightly with plastic wrap to hold it in place and trap moisture. Secure the top and bottom with twist ties, leaving them slightly loose at the top so you can add water later.
6. Check weekly. Peek through the plastic to check moisture. If the moss looks dry, open the top, add water with a squeeze bottle, and re-seal. The moss should stay consistently damp.
7. Roots appear in 3-6 weeks. You will see white roots growing through the moss, visible through the plastic wrap.
8. Cut and pot. Once you see a healthy network of roots filling the moss, cut the stem below the moss ball with clean shears. Unwrap the plastic (leave the moss attached to the roots) and pot the entire thing in a chunky potting mix. The roots transition to soil seamlessly because they developed in a moist, airy medium similar to soil.

Large Plant Division

If your Monstera has grown into a massive specimen with multiple stems emerging from the soil, you can divide it into separate plants:

1. Unpot the entire plant. This can be a two-person job for large Monsteras. Tilt the pot on its side and ease the root ball out.
2. Identify separate stems. Look for distinct stem groups, each with their own root system.
3. Separate carefully. Gently untangle roots by hand. If roots are too intertwined, use a clean knife to cut through them. Each division should have at least 2-3 leaves and a healthy portion of roots.
4. Pot individually. Plant each division in fresh, well-draining mix at the same depth it was growing before. Water thoroughly.
5. Expect some drooping. Divisions may wilt for a week or two as they recover from root disturbance. Keep soil consistently moist (not soggy) and provide bright indirect light. They bounce back once new roots establish.

Frequently Asked Questions

Can I propagate a Monstera without an aerial root?

Yes. Aerial roots speed things up, but they are not required. A cutting with just a node and a leaf will root perfectly well — it just takes a bit longer (4-6 weeks instead of 2-4). The node is the essential part; the aerial root is a bonus.

My Monstera cutting has been in water for 6 weeks with no roots. What is wrong?

First, confirm there is actually a node on your cutting — this is a very common reason for zero root growth. If there is a node, check your conditions: water should be changed weekly, light should be bright but indirect, and temperatures should be 65-80 degrees Fahrenheit. Cool temperatures dramatically slow rooting. Try adding a heat mat under the jar to maintain consistent warmth.

Will my propagated Monstera have fenestrations (holes)?

New leaves on a young Monstera cutting will be small and heart-shaped without fenestrations. Fenestrations develop as the plant matures and produces larger leaves — typically when the plant is at least 2-3 years old and climbing something (a moss pole helps). The cutting itself may have a fenestrated leaf, but new growth starts over from juvenile form.

Can I propagate a Monstera from just a leaf?

No. A leaf without a node will stay alive in water for a long time (Monstera leaves are tough), but it will never produce roots or new growth. You need a section of stem that includes at least one node. This is one of the most common propagation mistakes people make with Monsteras.
