fibrous roots should be pruned after flowering to promote re-flowering.

Graft before germination in spring or between July and September in autumn. Separate plants are propagated before germination in spring or after falling leaves in autumn and winter. Spring layering and root insertion. 

Before spring sowing, seeds must be treated with low temperature stratification for 30 to 100 days. After planting, the soil should always be kept loose and fertile, and the rhizosphere can be cultivated with pond mud or 

fertilized soil every autumn.

Spring for a pruning, cut off dead weak branches, keep the tree evacuation, ventilation and light to sow and reproduce, can also be laid or grafted. The seeds are sown in October, and the seeds are dried with the skins. 

The fruits are cut open when sowing and the seeds are taken out. You can also take out the seeds first, hide in the sand for winter, and sow in the spring of the next year. Layering is carried out in spring, small seedlings 

can be attached to the ground and pressed into the soil, and large seedlings can be used by high pressure method. Graft can be used as a stock for begonia or seedling, and cut in spring.

Primary value

The oil content of begonia seed kernel is 35.99%, the oil yield is 30%, no odor, can be eaten and can make soap. The fruit is steamed and candied; It can also be used as medicine, with the effect of driving wind, smoothing 

qi, relaxing tendons and relieving pain, and can cure alcohol and phlegm, simmer food and stop dysentery. Flowers can be used as ingredients for sugar sauces, and the flavor is very beautiful. The bark contains tannin,

Crabapple flowers are made of bonsai materials, cut branches can be used for bottles and other decorative purposes. Begonia flower has strong resistance to sulfur dioxide, which is suitable for urban street green space 

and mining area greening. In addition, some begonia fruit, can be eaten, medicinal. Flowers contain honey and are a good source of nectar. Crabapple trees beautiful, spring flowers in full bloom, after the autumn full of 

golden fruit trees, aromatic attack. It should be planted alone before and after the courtyard, at the entrance of the entrance hall, in the corner of the lawn, or with other flowers and trees. Can also dwarf potted plants.
