Although it can be trimmed in summer and autumn, it is not suitable. In summer, branches and leaves will be reduced, and it is difficult to form nutrition. When trees grow, nutrients cannot be supplied. Although it grows slowly in winter, it has little effect on plants, but it is difficult to prune and regenerate at this time.
To remove bad branches, we must first remove dead branches, yellow branches and branches with wounds. Then, the plants are thinned to remove dense branches, cross branches, long branches and weak branches, so as to reduce the consumption of nutrients and avoid rot caused by dense airtight branches. When pruning, the main excellent branches are left, and the number is kept at about 4.

Maintenance/curing
Begonia flowers are drought-tolerant, and there can be no excess water in the pot soil. Usually, as long as the soil is slightly wet, it is ok. The soil can't be too dry, its roots can't breathe, it's easy to dry and scorch, and serious water shortage can also lead to plant death.
The normal growth of begonia flowers needs enough sunshine, and short illumination time will affect their normal growth. In the hot weather in summer, it is necessary to shade to reduce the temperature and avoid strong sunlight, so it can be given plenty of sunshine in winter.
In autumn, the leaves of begonia flowers will fall off. At this time, it is necessary to apply more chemical fertilizers, preferably more phosphorus and potassium fertilizers. When flower buds are formed in spring, fully decomposed organic liquid fertilizer should be applied to them, and the fertilizer concentration can be appropriately increased during the vigorous growth period.
