Pruning
Pruning is essential for the plant's health and helps to promote new growth. It is best to prune the African tea plant during its dormant season, which is in the late winter or early spring. The plant can be pruned to remove dead and diseased branches, promote new growth, and maintain its shape.
Propagation of Gnidia scabra Thunb.
Gnidia scabra Thunb. can be propagated through various methods such as seeds, cuttings, and division.
Propagation through seeds
The plant produces small, black seeds. When propagating through seeds, the seeds need to be sown in well-draining soil. The seeds should be lightly covered with soil and kept moist. Germination of the seeds usually takes 2-4 weeks, depending on the conditions. The young seedlings can be transplanted into bigger pots or directly into the garden after they have grown 3-4 true leaves.
Propagation through cuttings
Gnidia scabra Thunb. can be propagated through stem cuttings. The best time to take cuttings is during the summer when the plant is actively growing. The cuttings should be taken from healthy, disease-free plants and should be 4-6 inches long. The lower leaves should be removed, and the cutting should be planted in well-draining soil. The cutting should be kept moist and warm (ideally between 18-25°C) and should root within 3-4 weeks. Once the cutting has rooted, it can be transplanted into a bigger pot or directly into the garden.
Propagation through division
Propagation through division is generally not recommended for Gnidia scabra Thunb. as the plant does not tolerate disturbance well. However, if you need to divide the plant, it is best done during the spring. The plant should be carefully dug up and the roots separated into smaller sections with a sharp, sterilized knife. Each section should have a good root system and should be planted in well-draining soil. The plants should be watered and kept in a shaded area until they are established.
