Apple trees should be pruned four times a year, and the effect of each pruning is different. Winter pruning is the basis of one-year pruning. It is necessary to prune the branches that are too dense in time, and at the same time prune the young trees properly. The old trees should be cut short, which is more helpful for their growth. After germination, the buds should be pruned and scored before the buds that are not easy to germinate to promote their branching. In addition, trees that have not been cut down in winter should be cut down again. After the bud appears, it will be relieved in time, so that the fruit will be fuller.

First of all, winter scissors

Winter is the dormant period of apple trees. After flowering and fruiting, a lot of nutrients have been consumed, and pruning is particularly important at this time. In view of the large canopy, it should be thinned in time to ensure internal ventilation and light transmission. Young trees should be pruned slowly to promote flower bud formation. Old trees need to be cut short to promote branching. It is necessary to remove some branches with more flower buds to ensure the supply of nutrients.

Second, pruning the buds.

Because the buds in the middle and back of apple branches are not easy to germinate, they should be pruned to germinate. It is necessary to carve a trace 0.5 cm in front of the bud, with a depth of about a quarter. At the same time, the buds on the competitive branches and the buds on the back of the auxiliary branches should be deducted to avoid consuming nutrients.

Third, cut your hair again.

Re-cutting is a supplement to winter cutting, which is usually carried out after germination. For slow-growing trees that have not been pruned in winter, they should be pruned again at this time. For trees that grow vigorously, only the backbone branches are cut in winter, and the rest are kept for re-cutting.

Fourth, sparse buds

Bud thinning is to ensure that the fruit is more nutritious and bears fuller fruit. Before flowering, that is, the middle and late April. Keep only the central flower and 1 lateral flower, and remove everything else, but keep the cluster leaves.
