Propagation of Combretum constrictum (Benth.) M.A.Lawson var. somalense Pamp.
There are several methods of propagating Combretum constrictum (Benth.) M.A.Lawson var. somalense Pamp. It can be propagated through seeds, cuttings, and layering techniques.
Propagation through seeds
One of the easiest ways to propagate this plant is through seeds. The seeds of Combretum constrictum (Benth.) M.A.Lawson var. somalense Pamp. need to be sown in well-drained soil. They should be covered with a thin layer of soil and kept moist until they germinate. It is best to sow seeds during the rainy season when the soil is moist. Germination usually takes place within 14 to 21 days.
Propagation through cuttings
Propagation through cuttings is another method that can be used. Semi-hardwood cuttings can be taken during the spring and early summer months. The cuttings should be about 10 cm long and should have at least one leaf node. These cuttings should be planted in well-drained soil and kept moist. It is best to keep them in a shady area until they develop roots. Once they have developed roots, they can be transplanted to their permanent position.
Propagation through layering techniques
Propagation through layering is another method that can be used. This method involves making a small cut in one of the stems of the parent plant and then burying this stem in the soil. The stem is kept in place with a bent wire or a small stone. After a few weeks, the buried stem will develop roots, and a new plant will begin to grow. The new plant can then be separated from the parent plant and transplanted to its permanent position.
