Pruning in dormant period is the main method for peaches, supplemented by pruning in growing period. Pruning during dormancy should be done after severe cold and before sap flows out in spring. The main purpose is to cultivate the skeleton and flower branches, enrich the branches, and cut off the branches that disturb the tree shape and affect the appearance.

Pruning mode

Pruning peaches at different ages have different growth characteristics. In order to make the whole pruning scientific and reasonable, the pruning characteristics of each age stage are divided.

① Early viewing period (4-6 years old). From the survival of grafting to the basic formation of main branches and primary lateral branches, this period is rich in nutrition, vigorous in growth, easy to branch and small in branching angle. Because peach trees have the characteristics of weak dryness and strong positive tree species, trees should be fixed in winter and main branches should be selected. At the same time, in summer, it is necessary to remove the core or bundle, sparse and dense branches, and increase the branching order to form a perfect tree in a short time.

② The best viewing period (6 ~ 25 years). From the basic formation of the crown to the aging of trees, the crown gradually expands, grows vigorously and blooms luxuriantly during this period, and the requirements for soil, fertilizer and water are urgent, but attention should be paid to the regeneration of branches to prevent aging.

Pruned peaches are strongly positive tree species under different environmental conditions and are quite sensitive to light. The same pruning, under different lighting conditions, the branches reflect different situations. It should be planted in front of the building, because the light difference between north and south is large, which leads to different growth conditions of branches. When pruning, the branches in the south should be properly drained, and the corners should be opened to let the sun shine in and ease the branches. Due to insufficient light in the north, many branches are thin, so the short cut should be in the place where the buds are full, and fewer branches should be cut to promote the branch potential.

There are many kinds of pruning methods for different garden layouts, and one method cannot be used for pruning. We should adopt different ways and pruning methods in different arrangements to enrich the landscape.

For example, peaches planted on a large lawn should form a relatively large tree body, so as to be in balance with the environment, and the pruning amount should not be too heavy, so as to maintain a natural posture. The tree type used should be natural and happy, or it can be pruned into a low, almost overgrown tree. When planting alone beside the rockery, we should pay attention to the posture of the tree, and the lines should be coordinated with the rocks that reveal the birth machine, so that the size of the tree is proportional to the size of the rockery. At this time, it should be trimmed into a natural cup pile scene. Pruning of clump trees should be carried out as a unified group. When pruning, we should pay attention to the unity and change of crown line, and also consider the ventilation and light transmission effect in the tree.

After pruning spring flowers in different seasons, they should be pruned again according to different environmental types. In other growing seasons, the branches that grow too vigorously, have pests and diseases, and affect the crown shape should also be pruned in time to avoid nutrient loss. Late autumn is an important season for pruning peaches after defoliation. According to the type of environment, an ideal crown shape can be formed in a short time.
