Propagation is an essential aspect of plant cultivation and involves the multiplication of plants from existing ones. Pleiospilos compactus subsp. minor can be propagated by different methods, including:
Seeds Propagation
The easiest and most common method of propagation for Pleiospilos compactus subsp. minor is from seeds. The plant produces capsules with very tiny seeds that can be sown immediately after harvesting. Sow the seeds in a well-draining soil mixture, cover lightly with sand or vermiculite, and keep them moist. Germination will occur after about two weeks, but it can take up to six months. The young plants should stay in the same pot for about two years before replanting.
Division Propagation
An alternative method to propagate the Pleiospilos compactus subsp. minor is division. This method involves the physical separation of a mature plant into two or more sections. To do this, remove the plant from its pot and gently separate sections of the plant’s stem by cutting through the roots with a sharp and sterile knife. Ensure each section has enough roots to establish itself. Replant each section in a new pot with a well-draining soil mixture and water well.
Leaf Cuttings Propagation
Pleiospilos compactus subsp. minor can also be propagated by taking leaf cuttings. Using a sharp knife, cut a healthy leaf from the plant, remove the base and allow it to heal. Once healed, place the leaf on top of a well-draining soil mixture, keeping it moist until it develops roots. After it has rooted, its first tiny leaves will appear at the base, and it can be planted in its own pot.
Propagation is an excellent way to multiply and expand your collection of Pleiospilos compactus subsp. minor. With proper care and a little attention, each new plant can grow and thrive, providing a new addition to your collection.
