Apple trees should be pruned four times a year. When pruning in winter, the branches that are too dense must be pruned in time, and the young trees should also be pruned appropriately. After the buds appear, they should be sparse in time.

Apple trees usually take about 4 years to bear fruit after cutting, so apple trees are usually cultivated by grafting. The apple branches are placed in wet sand, kept warm and moist, turned once every half month, soaked in rooting agent in the next spring, then inserted into the dug soil, and then inserted into rooting agent solution every half month.

Prune the branches and leaves of apple trees

Pruning: Cut off part of the annual branches of apple trees. According to the degree of pruning, it can be divided into light short cut, medium short cut, heavy short cut and extremely heavy short cut.

Thinning: Removing the branches from the base of an apple tree is called thinning, which is generally used when the branches in the crown are dense, overlapping, crossing, coexisting or short. Pruning pests and useless branches is also a pruning method.

Apple trees grow quickly after pruning.

Pruning in spring: during the period from germination to flowering, apple trees are pruned by means of coating buds, combing branches, shrinking branches, carving buds and peeling rings, including tearing branches.

Summer pruning: Apple trees adopt other techniques, such as angle opening, coring, girdling, thinning, girdling, kinking, etc., to reduce tree vigor, improve illumination and promote crown expansion.

Pruning in autumn: In autumn, apple trees need to improve light conditions, promote flower bud differentiation, improve cold tolerance by pulling branches, thinning branches, long branches and dense branches, and cut off too dense new shoots.

Pruning and flowering of apple trees

The flowering period of apple is generally from April to May, and it is a cross-pollinated plant. In order to make it blossom more, it is necessary to prune it in winter, establish a reasonable tree body mechanism, alleviate the contradiction of nutrient distribution in the tree, adjust the relationship between nutrient growth and reproductive growth, and make the apple tree grow better.

Apple trees will bear a lot of fruit after pruning.

From February, 65438 to February, 65438, the water content of apple trees was low, and the fruit trees entered the hibernation period, with strong drought resistance. This time is the best time to prune, and the weak trees and old trees should be pruned early.

Matters needing attention in apple tree pruning

Pay attention to the growth momentum of apple trees. Young trees grow vigorously. Pruning methods should be adopted, such as opening the angle of branches and slowly releasing them, so that vegetative growth will turn to reproductive growth and bear more flowers and fruits.
