Pruning is an essential part of maintaining the shape and size of the plant. Dead and diseased branches should be pruned immediately. Regular pruning helps the plant to develop a more bushy and compact growth habit. Pruning should be done during the dormant season, preferably in early spring, to allow the plant to recover before the growing season begins.
Propagation of Dalbergia pluriflora Baker f.
Dalbergia pluriflora Baker f., commonly known as African blackwood or mpingo, is a hardwood tree native to East and Southern Africa. The propagation of this plant can occur through various methods, including:
Seed propagation
The most common method of propagating Dalbergia pluriflora is through seeds. The seeds are collected from mature fruits and sown in well-drained soil. The ideal temperature for germination is between 20°C and 25°C. The seedlings take about four to six weeks to emerge. Once the seedlings have grown to about six inches, they can be transplanted to their permanent location.
Cuttings propagation
Dalbergia pluriflora can also be propagated using cuttings. Hardwood cuttings of about 2-3 inches are taken from the parent plant and treated with a rooting hormone. The cuttings are then planted in a rooting medium consisting of sand and peat moss. The rooting medium is kept moist, and the cuttings are covered with a plastic bag to maintain humidity. Rooting usually takes about six to eight weeks, after which the cuttings can be transplanted to their permanent location.
Grafting propagation
Grafting can also be used to propagate Dalbergia pluriflora. The scion wood is obtained from the desired cultivar, and the rootstock is obtained from a related species within the same genus. The scion is then grafted onto the rootstock and allowed to grow. Grafting is usually done during the dormant season, and the grafted plants are carefully monitored for any signs of disease or stress.
Regardless of the propagation method used, it is important to ensure that the young plants are given proper care and attention. This includes providing adequate water, nutrients and protecting them from pests and diseases.
