1、 Spring pruning

Spring is a suitable time for pruning. It is necessary to pick the heart and top in time to control the plant growth height. In this way, it is difficult for lateral branches to germinate. In addition, after maintenance for a period of time, the branches are easy to grow disorderly, and even some dead branches and yellow branches will appear. In addition, with the pest branches caused by poor ventilation, spring is a good time to prune the branches. If you want to cut off the branches with poor growth, it is useless to keep some thin and weak branches

2、 Pruning in summer and Autumn

Pruning in summer and autumn is very important. This time period happens to be after the flowers bloom and fail. Some will bloom and fail early in summer, and some will bloom and fail late in early autumn. Remove the remaining flowers first and don't stay on them, which can reduce the consumption of nutrients. Leave 3-5 nodes on the branches and cut off the top tip, which can promote the germination of new buds and vigorous flowering in the later stage

3、 Winter pruning

Winter pruning is also very suitable. It is just during dormancy. At this time, pruning has no much impact on the plant. First observe the whole plant. Cutting off some overlapping branches can not only reduce the consumption of nutrients, but also improve the lighting conditions and promote the penetration of sunlight
