Spring is the suitable time for pruning, so it is necessary to pick the core and top in time to control the growth height of the plant, and it is difficult for the lateral branches to germinate. In addition, after a period of maintenance, branches are prone to disorderly growth, and even some dead branches and yellow branches may appear. In addition, due to poor ventilation, branches are damaged by pests and diseases. Spring is a good time to prune branches, and it is useless to cut off branches that are not growing well.

2, summer and autumn pruning

Pruning in summer and autumn is very important. This time period is just after the flowers bloom and fall. Some flowering periods will blossom and drop fruit in early summer, while others will blossom and drop fruit in early autumn. Remove the residual flowers first and don't leave them on them, which can reduce the consumption of nutrients. Leave 3-5 knots on the branches and cut off the top to promote the germination of new buds and flourish in the later stage.

3, winter pruning

Seasonal pruning is also suitable, just in the dormant period, when pruning has little effect on the plants. Observing the whole plant first and 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.
