First of all, the pruning of begonia flowers should be carried out before and after flowering, which is not suitable for pruning. Begonia flowers germinate in early spring. At this time, our minds are pruned once and for all, and the whole plant is thoroughly inspected, and the dead branches, weak branches, pests and diseases branches, cross branches and over-dense branches on the plant are cut off, so that the whole plant can concentrate nutrients and promote the growth of new buds. It is necessary to pay attention to cut off some long branches and leaves according to the needs of begonia flower modeling, promote lateral branches, increase the number of flower branches, and ensure the only flowering in the coming year.
After the flowering period of Begonia is over, about two weeks after the flowers wither, you can trim the branches and leaves and sparse some withered flowers. Cut off the dense branches and shorten the prominent branches appropriately to make the whole plant more breathable. 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.
Pruning after defoliation: After defoliation of begonia, extra branches should be pruned in winter to preserve nutrition. Pruning after defoliation can accumulate nutrients for the growth of begonia flowers in the coming year, and can also shape the plants. Then, all the pests and diseases should be cleaned up in winter to prevent the next year's begonia flower growing season from causing pests.
When pruning begonia flowers, it is best to cut off some withered branches and leaves at the same time, otherwise it will also cause nutrient waste, especially potted begonia. It is necessary to remove litter in time and reduce the area of photosynthesis, thus inhibiting the growth of begonia flowers and reducing the consumption of nutrients.
In the process of pruning begonia flowers, we must pay attention to the fact that different plants occupy different spaces. We should decide how many branches to cut and how many to keep according to the size of the space.
In addition, when pruning during dormancy, be careful not to cut off the full branches that grow short in the first year. At the same time, excessive use of nitrogen fertilizer should be controlled when fertilizing. Wild pea-boric acid high-fat film should be applied.
