Pruning is essential to maintain the plant's shape and size. Dead or diseased branches should be removed immediately to prevent the spread of disease. Regular pruning will encourage growth and increase the plant's overall health. It is recommended to prune the plant during the spring or summer months after flowering.
Propagation of Cynometra mundungu Pellegr.
Cynometra mundungu Pellegr. can be propagated through seeds, cuttings, and air layering.
Propagation by Seeds
The seeds should be collected from mature fruit, washed and then soaked in water for 24 hours to soften the hard seed coat. After the soaking, the seeds can be planted in a well-drained potting mix in containers or directly in the field. The seeds will germinate within 2-3 weeks.
Propagation by Cuttings
Cuttings can be taken from semi-hardwood or hardwood stems. The cuttings are typically about 15-20 cm long with a few leaves at the top. The cuttings should be treated with rooting hormone and then planted in a well-drained potting mix. The container should be covered with plastic to retain humidity. After 2-3 weeks, the cuttings will begin to produce roots.
Propagation by Air Layering
Air layering is typically done in mature plants that are at least a year old. A ring of bark is removed from a branch about 15-20 cm from the tip. The exposed area is then treated with rooting hormone and covered with moist sphagnum moss, which is then wrapped with plastic to retain humidity. After 4-6 weeks, roots will form in the moss. The rooted section of the stem can then be cut off and planted in a well-drained potting mix or directly in the field.
