Propagation of Combretum usaramense Engl.
Propagation of Combretum usaramense Engl. can be done through seeds and vegetative methods, such as stem cuttings.
Seed Propagation
The seeds of Combretum usaramense Engl. are viable and can be used for propagation. The best time to collect seeds is during the dry season, from June to August. Seeds can be collected from mature and healthy trees. The collected seeds should be cleaned and stored in a cool and dry place for future use.
Before sowing the seeds, they should be soaked in water for 24-48 hours. This helps to soften the hard seed coat and allow for better germination. Seeds can be sown in seedbeds or pots filled with well-draining soil. They should be covered lightly with soil and kept moist. Germination can take 3-4 weeks, after which the seedlings can be transplanted to individual containers.
Vegetative Propagation - Stem Cuttings
Vegetative propagation can be done through stem cuttings. The best time to take stem cuttings is during the rainy season, from November to February. Cuttings can be taken from healthy and mature trees. The cuttings should be approximately 20-30cm long and have at least 3-4 nodes.
The cuttings should be treated with rooting hormone and planted in well-draining soil. They should be maintained in a warm and humid environment. Covering the cuttings with a plastic bag can help to maintain humidity. The cuttings will take root in 3-4 weeks and can be transplanted to individual containers.
