1. Sowing propagation: Begonia obovata can be propagated by sowing, as long as the seeds are mature and the environment is suitable, the emergence rate can reach about 70%.Prepare the soft and fertile soil, scatter the seeds on it, cover them with a fine layer of soil, and water them for germination.After germination, seedlings can be thinned and strong seedlings can be left behind.
2. Cuttage propagation: Cuttage is a common propagation method for Begonia obovata. Its leaves are relatively large and have strong regeneration ability. It is easy to grow adventitious roots after cutting the veins.Usually, clean river sand is used as a substrate, the back of the leaf is scratched, and then the leaf is laid face up on the sand, and the petiole can be inserted into it.After cutting, it should be pressed with glass, not completely covered, and a little gap should be retained.Callus usually develops in 20 days, new roots and leaves grow in 35 days, and then ventilation is maintained.
3. Division propagation: Begonia obovata can also be propagated by division method.Usually combined with repotting, the plant is taken out of the pot, divided into several clumps, and then planted separately.After potting, we should first put it in a semi-shady place, water it properly and wait for the potting, and then carry out normal maintenance after restoring growth.
The leaves of the ornamental begonia can be propagated.Its leaves have a strong ability to regenerate, and can be stimulated to grow adventitious roots and adventitious buds by cutting, which can be used for cutting to grow new plants.
