When the seedlings reach 20 cm in height, they can be transplanted to their permanent location.
Propagation through stem cuttings
Propagation through stem cuttings is a quicker method than seed propagation. The stem cuttings should be collected from the mother plant during the growing season. The cuttings should be about 15 cm long, with at least two nodes. The lower leaves should be removed, and the cuttings should be treated with a rooting hormone. The cuttings are then planted in a well-drained mixture of soil and sand. The cuttings should be kept in a humid environment to prevent water loss. The roots will develop within a few weeks, and the cuttings can be transplanted to their permanent location.
Propagation through root cuttings
Propagation through root cuttings is another method that can be used to propagate Rauvolfia macrophylla. The root cuttings should be collected during the dormancy period. The roots should be about 10 cm long, and the cuttings should be made using a sharp knife. The root cuttings should be planted in a well-drained mixture of soil and sand. The cuttings should be kept in a humid environment until they start to develop new shoots. The new plants can be transplanted to their permanent location once they have a well-established root system.
Overall, there are several methods that can be used to propagate Rauvolfia macrophylla Stapf. Each method has its advantages and disadvantages, and it is up to the grower to decide which method to use.
