Begonia sessilifolia has strong germination ability, and it is easy to grow long branches after strong cutting, so it is not suitable for strong cutting when it is young. After the crown is formed, attention should be paid to pruning the small side branches, so that the hidden buds at the base gradually germinate into branches and the flower branches cling to the side branches. If you want to expand the crown, you can cut off the vertices of the side branches and leave 1 ~ 2 long branches; When the long branch grows to a certain length, the top of the long branch is shortened to make it continue to form a long branch; Cut off the short and medium-sized flower branches behind the branches. If the branch is too long, the top can be trimmed properly to make the meristem blossom. Small lateral branches, alternately contracting and pruning every year, alternately expanding. After 5 ~ 6 years, select the branches that grow vigorously at or near the base for replacement. It can also keep a trunk below 1m, and the lateral branches grow naturally. Cut off the excessively elongated branches in winter and prune them immediately after flowering. Flourishing and flourishing. In May, 1/4 long branches can be cut off, and messy branches can be cut off. Prune the long branches of13 in winter, and cut the useless crowded branches from the base.
