Propagation of Angraecum chailluanum Hook.f.
Angraecum chailluanum Hook.f., commonly known as the "Chaillet's Angraecum," is a species of orchid that can be propagated through a few different methods. Here are some of the most commonly used techniques for propagating Angraecum chailluanum:
Propagation by Division
One of the easiest ways to propagate Angraecum chailluanum is by division. This method involves dividing the plant into sections, each with its own roots and leaves.
To propagate Angraecum chailluanum by division, carefully remove the plant from its pot and gently separate the roots into two or more sections. Each section should have roots and leaves, and it's best to avoid damaging the roots as much as possible.
Once you have separated the plant, plant each section in its own pot with fresh potting mix and water it thoroughly. Keep the newly divided plants in a warm and humid environment until they begin to establish themselves.
Propagation by Seed
Another method of propagating Angraecum chailluanum is by seed. This technique is more complicated than division and requires more time and effort, but it is a good way to create a large number of new plants.
To propagate Angraecum chailluanum by seed, you will need to pollinate the plant's flowers. Use a soft brush or cotton swab to transfer pollen from one flower to another, ensuring that each flower is pollinated.
Once the flowers have been pollinated, wait several months for the seed pods to mature. When the seed pods are ready, collect them and carefully remove the seeds from them.
Plant the seeds in a suitable potting mix and keep them in a warm, humid environment. Be patient, as it may take several months to see any growth from the seeds.
Propagation by Keiki
Finally, Angraecum chailluanum can also be propagated through a process known as keiki production. Keikis are small plantlets that grow from a parent plant and can be removed and potted on their own once they are large enough.
To propagate Angraecum chailluanum by keiki, you will need to wait until the plant produces one or more small plantlets. Allow the keikis to grow until they have developed roots and then carefully remove them from the parent plant.
Pot the keikis in their own pots with fresh potting mix and keep them in a warm, humid environment until they have established themselves.
Propagation can be a rewarding way to create new Angraecum chailluanum plants and to share this beautiful orchid with others.
