1, pruning time: winter pruning is carried out after defoliation, not too early.If it is pruned before defoliation, it is easy to appear early in the later period, so that it may not blossom next spring.
2. Principle of pruning: The overall pruning should be carried out according to the principle of one foot in length and eight inches in retreat.Usually, the third and fourth axillary buds differentiate, and the fourth and above buds will die slowly, so the fourth and above axillary buds should be cut off.
3. Pruning steps: When pruning, first cut off the dead branches, diseased branches and thin and weak branches.If the big seedling pruning, to sew three to one, that is, three branches together to cut off the middle branch.Of course, it is necessary to cut off the too small.Also trim the long branches that are too dense, leave the curved ones, and cut the straight ones, so as to adjust the overall shape.When retaining the bud point, we should leave it outward, so that the growth space of new branches is more sufficient and the plant shape will be more beautiful.
It has a certain degree of cold resistance, not afraid of freezing, will not freeze to death.However, in winter, we should pay attention to management methods, and there is almost no need to worry about it in the southern region, which can also be put outdoors for winter.The temperature in the north is low, or it is recommended to take cold-proof measures to avoid frostbite.It can be earthed in time, branches can be wrapped with grass felt, or a simple greenhouse can be built to put all the plants in, so as to ensure that they are not frostbitten.
