Propagation of Begonia Oxyloba Welw. ex Hook.f.
Begonia oxyloba Welw. ex Hook.f. is a beautiful, showy flowering plant that is native to tropical Africa. It is a member of the Begoniaceae family and can be propagated using several methods, including stem cuttings, leaf cuttings and division.
Propagation by Stem Cuttings
Propagation of Begonia oxyloba from stem cuttings is a popular method. Here, healthy stems are selected, taking care to cut them just below a node. These cuttings are then stripped of their lower leaves and planted in a well-draining rooting medium. The cuttings should be kept moist, but not waterlogged. In a few weeks, new roots will emerge from the base of the cutting. Once a sufficient root system has formed, the cuttings can be transplanted to their new location.
Propagation by Leaf Cuttings
Propagation of Begonia oxyloba from leaf cuttings is another commonly used method. Healthy leaves are selected and cut into small pieces, each containing a section of the central vein. These leaf cuttings are then laid flat on top of a moistened, well-drained soil mix. The cuttings should be kept moist and warm, and misted regularly. In a few weeks, new plantlets will emerge from the base of the leaf cutting and can be transplanted to their new location once they are established.
Propagation by Division
Begonia oxyloba can also be propagated by division. Established plants can be carefully lifted from their pot or bed and divided into smaller plants, each with its own root system. The divided plants should be potted up in a well-drained medium and kept moist until they are established. This method can be used to expand the plant's population or to rejuvenate older plants.
