When is the best time to cut peach trees in winter?

Thank you for inviting me! When is the best time to cut peach trees in winter?

First of all, I want to say that peach trees should also be cut in winter to distinguish between northern peach trees and southern peach trees. The time of winter cutting must be different.

Some northern varieties are prone to flower bud freezing injury, so southern varieties can generally start winter cutting in early or late February of 12, while northern varieties should miss the lowest temperature stage of 12, and it is best to do winter cutting in early or middle February.

Pruning too early or too late will lead to a large loss of nutrients in the tree, which will affect the vitality of the tree and adversely affect flowering and fruit setting.

When pruning in winter, we should also pay attention to distinguish varieties, and the methods of pruning in winter are different.

First, prune according to the cultivation area. In areas with less annual precipitation, the growth of peach branches is small, and only heavy and short cuttings can produce good fruits and branches.

Secondly, prune according to the variety group. The southern variety group has a large opening posture and moderate growth potential. Generally, when pruning, the degree of short cutting should be heavier, leaving medium and long fruit branches to bear fruit. The tree posture of the northern variety group is relatively upright and its growth potential is relatively strong. Generally, when pruning short branches, it should be lighter, and more short fruit branches and bouquets of short fruit branches should be left for fruiting.

Thirdly, pruning is carried out according to the branch type. For extended branches, the degree of pruning and pruning is based on the principle that there are many branches and the base is not bald. Generally, after all kinds of elongated branches are cut short, the lateral buds on them germinate one after another, and the long fruit branches, middle fruit branches and short fruit branches grow from top to bottom. Only the buds at the most basal part of 5 cm do not germinate into branches and become ear buds, which is the most suitable cutting degree. For long branches, except for the lateral branches, lateral branches, inner branches and fruiting branches in the exposed part of the crown, the other long branches are drained from the base.

Generally speaking, excessively long fruit branches should be pruned, so that they can bear 3-4 fruits, grow many long, medium and short fruit branches, and cultivate fruit clusters or fruit branches, which can bear fruit for many years. For long fruit branches, they should be shorter and heavier than long fruit branches. Let them bear 2 ~ 3 fruits, grow 2 ~ 3 fruit branches and cultivate fruit branches, which can last for 2 ~ 3 years. Generally, the middle fruit branch is cut heavier than the long fruit branch, so that it can bear 1 ~ 2 fruits and emit 1 ~ 2 fruit branches for 2 ~ 3 years. Short fruit branches are generally heavier than middle fruit branches, so that they can bear 1 fruit, or they can't bear fruit in the same year and grow 1 fruit branches, but can bear fruit 1 ~ 2 years or longer.

Short bouquets of fruit should not be cut short. This kind of fruit branch in the northern variety group can bear good fruit, while this kind of fruit branch in the southern variety group is generally sparse from the base. For the secondary branches, planting them in the middle and lower part of the extended branches can result in short cutting, while the secondary branches planted in long branches and long fruit branches are cut off by pruning.
