Pruning time: after defoliation in winter to before germination in spring. Pruning method: If the young trees have just been planted and grow vigorously, they can be pruned appropriately and the long branches can be shortened to save nutrients and promote the growth of the main branches. If the fruit trees are planted for a long time, the branches, dead branches and diseased branches that grow too densely should be cut off, and more lateral branches should be left to adjust the column shape; Some main branches should be trimmed by ring cutting to control nutrient transport and make them blossom more.

First, the pruning time

Apple trees grow slowly, and it is not easy to grow new branches, especially after bearing fruit. Therefore, special attention should be paid to pruning, preferably after defoliation in winter and before germination in spring. At this time, it does not affect its germination in winter and the next year. On the contrary, it can keep the branches warm, which is beneficial to overwintering and can promote the differentiation of branches and buds.

Second, the pruning method

When pruning, the pruning method should be changed according to the growth years of fruit trees. If it is a newly planted shoot, it can be pruned properly if it grows vigorously. Cut the long branches short, preserve nutrition and promote the growth of the main branches. If the fruit trees are planted for a long time, you should cut off the branches, dead branches and diseased branches that grow too densely, and leave more side branches to adjust the column shape. In addition, some main branches should be cut and trimmed, which can control the loose nutrition and make them bloom more.

If some fruit trees are not growing well, they should be pruned again, which can stimulate their growth and gradually restore their growth. Pruning should start with full leaf buds, leaving more side branches on both sides and less back branches. Leave more fruit on the big branches and less fruit on the small branches.

Third, matters needing attention

If you want fruit trees to bear more and bigger fruits, it is not enough to prune them only in winter, but also comb them in time when they bear fruit. Remove the ones that are too dense, otherwise it will affect the growth, lead to the reduction of most fruits and reduce the yield.

brief introduction

Apples are deciduous trees. Usually trees can be as high as 15 meters, but cultivated trees are only about 3-5 meters high. The trunk is grayish brown, and the bark has fallen off to some extent. The flowering period of apple trees depends on the local climate, but it is generally concentrated in April-May. Apple is a cross-pollinated plant, and most varieties cannot bear fruit by themselves.
