The time of pruning must be well chosen. Spring and autumn are suitable, spring temperature is suitable, and the growth speed is fast. After pruning, it can germinate quickly, which will not affect the growth of the plant. In autumn, the growth just slows down and the nutrients needed are reduced. At this time, the pruning effect is less. Although it can be pruned in summer and autumn, it is not suitable. In summer, the branches and leaves will be reduced and it is difficult to form nutrition. When the tree grows, the nutrition supply is not up. Although the growth is slow in winter, the impact on the plant is small, but at this time pruning, regeneration is more difficult.
1. Thinning and cutting branches: the branches of the plant need to be pruned. To remove the bad branches, first remove the dead branches, yellow branches and the branches with wounds. Then, the plants were thinned to remove the dense branches, Cross branches, long branches and weak branches, reduce the nutrient consumption, and avoid the branches from being dense and airtight and causing rot. When pruning, leave the main good branches, the number of branches to keep around 4
2. Before and after flowering: before and after flowering, pruning is required to accumulate sufficient nutrients for flowering. Prune for a period of time before flowering, so as to accumulate energy for flowering, remove the residual flowers after flower failure, and cut the flower branches properly.
