- Do not remove more than one-third of the plant's growth in a single pruning session.
Propagation of Fernandoa Mortehani
Fernandoa mortehani is a rare plant that is usually found in the tropical forests of West-Central Africa. The plant can be propagated using stem cuttings, root cuttings, division, or seed. However, seed propagation is the most successful method.
Propagation by Seeds
Seeds should be collected when ripe and sown immediately. Seeds that are stored for too long have a lower germination rate. The seeds can be sown in trays containing a well-draining soil mix.
The trays should be kept in a warm, humid, and shaded area until germination. Once the plants reach a size of about 2 inches, they can be potted up into individual containers to grow on before transplanting.
Propagation by Stem Cuttings
Stem cuttings can be taken from the plant during the growing season. The cuttings should be about 4 to 5 inches long and should be taken from the tip of the stem. The leaves should be removed from the bottom of the cutting, and the cut end should be dipped into a rooting hormone. The cuttings should be placed in a well-draining soil mix and kept in a warm, humid, and shaded area.
The cuttings should be kept evenly moist and misted regularly to maintain high humidity levels until roots develop. It usually takes about 4 to 6 weeks for roots to develop. Once the roots have formed, the new plant can be potted up into a larger container and grown on until it is large enough to transplant into the garden.
Propagation by Division
The plant can be propagated by division during the growing season. The plant should be carefully dug up, and the roots should be separated into smaller sections. Each section should have at least one shoot and some roots attached. The sections can be potted up into individual containers or planted directly into the garden.
The new plants should be kept well-watered until they establish themselves in their new location.
Propagation by Root Cuttings
Root cuttings can also be used for propagation. Root cuttings should be taken from the plant during the dormant season. The cuttings should be about 2 inches long and should be taken from the thicker roots. The cuttings should be planted in a well-draining soil mix and kept moist until new shoots emerge from the cuttings.
The new plant can be potted up into a larger container and grown on until it is large enough to transplant into the garden.
