The best time is near germination. When the temperature is just right, the growth rate is faster and it is easier to recover. If the time is too early, the wound will lose water easily, which will have an adverse effect on the later growth and even the branches will die. If the time is chosen too late, the growth and germination have already begun, and the new shoots and branches have accumulated nutrients, so they are hastily pruned and wasted.

2, pruning method:

(1) Spring: the best period, which can remove the top, inhibit the top effect, control the height, promote the appearance of side branches, and make the plants lush and plump.

(2) Summer: The purpose of pruning at this time is to reduce the ineffective growth of new shoots and promote flowering and fruiting as soon as possible. In addition to coring, we should also wipe off the buds that are not growing well and leave strong buds. Some branches that grow too densely should also be removed to increase the light transmittance.

(3) Winter: When it enters the dormant period, it is necessary to cut short and cut off some long branches to make the branches thinner.
