Cultivation methods of Begonia flowers:

Sewing, division and grafting are commonly used for propagation. Grafting is the main method, but layering and division can also be used. The sowing method is only used for breeding. The grafting rootstocks are mostly Catalpa japonica or Vitex japonica. It is resistant to extensive cultivation and has wide adaptability. During cultivation, you only need to irrigate and fertilize properly, and pay attention to shaping and pruning to ensure healthy plants and abundant flowers.

Sowing can be done in autumn or in spring after hiding in the sand. Seedlings grow slowly, take 5-6 years to bloom, and often mutate, so they are only used for rootstock cultivation and hybrid breeding.

Horticulture varieties are mostly propagated by grafting. Vitex or crabapple seedlings are used as rootstocks. Branch grafting and bud grafting are both possible. Branch grafting can be done by cut grafting or split grafting. Bud grafting is mostly done by the "T" shape grafting method. . Branches are mostly planted in early spring before budding or after leaves fall in autumn and winter.
