Adanson's Monstera (Monstera adansonii) Propagation

Adanson's Monstera propagation can be done at the beginning of the growing period by use of stem cuttings or by air layering. The stem cuttings can be rooted in soil or in water.

How to propagate Adanson's Monstera from stem cuttings in soil

Take a stem cutting from a healthy Adanson's Monstera by cutting at a point just below an aerial root.

Just one leaf node with the leaf is enough to propagate a new Adanson's Monstera.

Insert the Adanson's Monstera cutting in moist free-draining soil. Ensure the rooting container has proper drainage to avoid getting soggy soil.

Place the set up in a well-lit, shaded place and maintain the soil moist until new growth emerges.

Allow the new Adanson's Monstera to be well established before transplanting after which routine care can begin.

How to propagate Adanson's Monstera from stem cuttings in water

Take a stem cutting from a healthy Adanson's Monstera by cutting at a point just below an aerial root.

Just one leaf node with the leaf is enough to propagate a new Adanson's Monstera.

Place the cutting in a jar containing plain water while ensuring that at least one leaf node is under water.

Place the set up in a well-lit spot and change the water every 7-10 days.

Once adequate roots have developed, plant the Adanson's Monstera cutting in soil and place in a well-lit shaded place.

Allow the new Adanson's Monstera to be well established before transplanting after which routine care can begin.

How to propagate Adanson's Monstera by air layering

There are two methods of air layering Adanson's Monstera.

One method consists of notching the stem of a healthy Adanson's Monstera and coating the notch with a rooting hormone.

Surround the notched area with damp moss and then cover it with a polythene film or clear plastic wrap.

After the roots have formed sever the stem just below the covered part.

Remove the polythene and carefully pot the rooted cutting in moist free-draining soil.

Place in a shaded well-lit place and maintain the soil moist until the new Adanson's Monstera is well established.

The second way involves coating the stem at a node with a rooting hormone.

Surround the node with damp moss and then cover it with a polythene film or clear plastic wrap.

After the roots have formed sever the stem just below the covered part.

Remove the polythene and carefully pot the rooted cutting in moist free-draining soil.

Place in a shaded well-lit place and maintain the soil moist until the new Adanson's Monstera is well established after which routine care can begin.
