How and when to prune begonia flowers?

1. Spring pruning: In spring, begonia flowers need a lot of nutrients. Prune dead branches, weak branches, insect branches, cross branches, overlapping branches and excessive branches of begonia flowers to promote the germination and growth of new buds. According to the shape of begonia flower, it is necessary to cut off some long branches and promote lateral branches to increase the number of flower branches and ensure the next year's flowering;

2. Pruning after flowering: Prune the branches and leaves of begonia two weeks after flowering according to the different flowering periods of begonia. Cut off crowded branches and protruding branches. Long branches can be truncated to keep 3 to 4 buds at the base. This is beneficial to increase the short branches that form flower buds;

3. Pruning after defoliation: dead branches, weak branches, pests and diseases, cross branches, overlapping branches and excessive branches after defoliation. For the better growth of begonia flowers in the coming year and the maintenance of nutrition in winter, the branches of begonia flowers should be trimmed;

4. Pruning after flowering: Pruning with branches with leaves after flowering can reduce the area of photosynthesis, inhibit the growth of begonia and reduce the consumption of nutrients.

Pruning period: spring, after flowering, after defoliation and after flowering.
