1、 Pruning method

Its old pile mainly prunes the branches when pruning. Cut short the long branches, and cut off the dead branches, weak branches and pest branches in the tree crown, which can not only reduce the loss of nutrients and make the remaining branches stronger, but also make the plant shape more beautiful. In addition, it can form flower buds every other year, and the flowers usually grow on new branches, and there are few flowers on old branches. Therefore, the old branches that have bloomed can also be cut off, which can also reduce nutrient consumption and promote the flowering of new branches

2、 Pruning time

Its pruning is mainly after the flowering period, specifically between March and June. It is not recommended to prune after July, which will affect flowering and plant growth. In addition, the old piles can also be trimmed in winter every year. Only the branch strips can be cut. At this time, it should be cut gently. However, it is a relatively shear resistant plant with strong branching ability. Don't be afraid of being cut bad, and you can recover soon
