Begonias are mainly cultivated from cross breeds in a variety of ways. A mature portion can be cut from the main stem of the Cane species and be used as stem cutting for propagating the plant. The cut portion of begonias should first be dipped in rooting hormone for one hour, to enhance root development.
Cane species have both male and female flowers and hence the seeds of the female flowers should be used for propagation. But in the case of Rex, mature leaves are used for propagation. Stems are used on rare occasions. The nodes of the leaves can be buried completely in the potted mixture in this case.
Another popular begonia cultivation technique is by cutting the leaves in a triangular shape and planting them in such a way that the leaf veins are buried in the mixture.
The hanging varieties of begonias can be cultivated through stem propagation. The potting mixtures are different for all different varieties of the begonia. It can be prepared by mixing loose soil and cow dung cakes in the ratio of 9:1. Applying moist coco peat at the base of the pot can help in draining moisture content of the soil.
Irrigation must be done minimally according to the requirement of the species cultivated. It is also recommended to move the pot to a shady region.
