Propagation of Diosma wittebergensis Compton
Diosma wittebergensis Compton, also known as the Witteberg buchu, can be propagated using various methods including seeds, cuttings, and layering.
Propagation by seeds:
The most common and recommended propagation method for this plant is through seeds. The seeds can be sown in a well-draining potting mix in a seed tray or directly in the garden bed. Ensure that the soil is kept moist and placed in a bright but sheltered position. Germination usually occurs between 4-8 weeks.
Propagation by cuttings:
Diosma wittebergensis Compton can be propagated by taking semi-hardwood cuttings in summer. Select a healthy stem with 2-3 pairs of leaves. Remove the lower leaves and dip the cut end into a rooting hormone powder. Plant the cutting in a well-draining potting mix and keep it in a partly shaded position. Water regularly and keep the soil moist until roots develop in around 4-6 weeks.
Propagation by layering:
Another simple propagation method for this plant is through layering. In spring, select a healthy stem that is low to the ground and that can be bent down to the soil surface. Remove a section of the bark where the stem touches the soil and place it in contact with the soil. Secure it in place using a small stake or rock. Keep the soil moist and wait until roots develop from the buried stem in around 6-8 weeks. Once the roots have developed, sever the new plant from the parent plant and plant it in a new location.
