Pruning
Pruning Rinorea oubanguiensis Tisser. is not necessary, but it can help maintain a healthy and attractive plant. Pruning should be done in the early spring before the growing season starts. Cut back any dead or diseased branches, and remove any branches that are crossing or rubbing against each other. If the plant has become too large, it can be trimmed back to a more manageable size. However, it is essential not to remove more than one-third of the plant at any one time.
Propagation of Rinorea oubanguiensis Tisser.
Rinorea oubanguiensis Tisser. is a tropical plant that can be propagated by both sexual and asexual methods.
Sexual Propagation
Seeds of Rinorea oubanguiensis Tisser. can be sown in the field or in containers. The seeds should be collected from mature fruits and dried for a few days. Germination usually occurs within 10-14 days after sowing. The seedlings can be transplanted to a bigger container or directly to the field after they have developed their true leaves.
Asexual Propagation
Rinorea oubanguiensis Tisser. can also be propagated asexually by stem cuttings. The cuttings should be taken from a healthy mother plant and should be 6-8 cm long. The leaves on the lower part of the cutting should be removed, and the cutting should be treated with a rooting hormone. The cutting can then be planted in a potting mix and watered regularly. Within a few weeks, the cutting should root and can be transplanted to a bigger container or to the field.
