1、 Pruning time

The pruning time must be selected well. Spring and autumn are more suitable. The temperature in spring is suitable and the growth speed is fast. After pruning, it can germinate quickly without affecting the growth of the plant. In autumn, the growth just slows down, and the nutrients needed are reduced. At this time, pruning has little impact. Although pruning can be done in summer and autumn, it is not suitable. The branches and leaves will be reduced in summer, so it is difficult to form nutrition. When the tree grows, the nutrition supply is not enough. Although the growth is slow in winter and has little impact on the plant, it is difficult to prune and regenerate at this time

2、 Pruning method

1. Thinning branches: the branches of the plant need to be trimmed. Remove the bad branches. First remove the dead branches, yellow branches and branches with wounds. Then thinly cut the plants to remove dense branches, Cross branches, long branches and weak branches, reduce nutrient consumption and avoid decay caused by dense and airtight branches. When pruning, leave the main excellent branches, and keep the number at about 4

2. Before and after flowering: pruning is needed before and after flowering to accumulate enough nutrients for flowering. Prune for a period of time before flowering, so as to accumulate energy for flowering. After the flowers fail, remove the residual flowers and cut the flower branches appropriately
