Propagation of Elaeodendron zeyheri Spreng. ex Turcz.
Elaeodendron zeyheri Spreng. ex Turcz. is a tree that belongs to the Celastraceae family and is native to Southern Africa. It is commonly found in wooded grasslands, rocky hillsides, and forests. Propagation of this plant can be done through both sexual and asexual methods.
Sexual Propagation
Propagation of Elaeodendron zeyheri Spreng. ex Turcz. through sexual methods involves collecting seeds from mature trees during the fruiting season. The seeds should be cleaned and planted in well-draining soil mixed with compost, and kept moist but not waterlogged. Germination usually takes place within 3-4 weeks, and the seedlings can be transplanted to their permanent location after they have grown to a suitable size.
Asexual Propagation
Asexual propagation of Elaeodendron zeyheri Spreng. ex Turcz. can be done by stem cuttings or layering. Stem cuttings should be taken in early spring from the current year's growth. The cuttings should be approximately 20-25cm long with a few leaves and no flowers or buds. They should be rooted in a mixture of compost and sand, and placed in a warm and humid environment until they develop roots. Once rooted, the cuttings can be potted up in individual containers and grown until they can be planted in the ground.
Layering is another asexual propagation method that involves bending a low-lying stem to the ground and covering it with soil. Roots will develop at the nodes, and once they have taken hold, the stem can be cut from the parent plant and transplanted to its permanent location.
