Does the apple need pruning? When is the best time to trim?
Pruning of apple trees is a major technical measure in integrated management of fruit trees. Scientific and reasonable pruning can make the fruit trees grow fast, take shape quickly, make the skeleton firm, distribute the branches reasonably, make the trees ventilated and transparent, produce high yield and high quality, make the orchard reasonable and close planted and convenient to manage, improve work efficiency, reduce labor intensity and production cost, and increase the economic benefits of apple trees.

The necessity of pruning apple trees

1 when cultivating high-yield tree structure, apple trees should cut off many branches lightly and keep fruit shape at the same time, so that young trees can form early, grow fast and bloom early, and realize early fruit and high yield.

On the premise of achieving stable and high-quality precursors, apple trees should adjust the tree structure, solve the problem of light path, make the tree strong and ventilated, prolong the fruit-bearing period, and achieve high-quality and stable production.

If the fruit trees are not pruned, if they are allowed to grow naturally in the process of growth and development, without manual management and control, it will inevitably lead to tree height, dense branches, few flowers, tree closure, premature senescence of fruit trees, insufficient illumination, bare inner cavities, small apples, poor quality, unstable yield, serious years and low economic benefits.

Proper pruning of apple trees

With the continuous development of fruit tree pruning technology, it has changed from a single traditional winter pruning to four-season pruning and perennial pruning of fruit trees, especially apple trees, and can be pruned many times throughout the year.

1 Apple Tree Pruning in Winter (Pruning in Dormancy)

Pruning fruit trees from normal defoliation in winter to germination in spring is called winter pruning, and it is best to avoid the coldest weather in winter on March 9. At this time, pruning the branches of fruit trees is easy to dehydrate, and at the same time, freezing injury occurs, causing branch diseases. Pruning too late will cause the loss of storage nutrition after the juice flows, especially weakening the tree potential. Pruning fruit trees too early and too late in winter is not good for pruning fruit trees. It is best to prune apple trees after the weather on March 9 and before germination.

2 spring pruning of fruit trees

Pruning apple trees in spring is to reduce the consumption of ineffective nutrients, store nutrients in a centralized way, supply apple trees with flower buds, shrink or adjust branches when the flowers are big, and play a role in thinning flowers and saving fertilizer. Pruning the prosperous trees in the later stage plays a role in controlling prosperity and slowing down the trend, which is conducive to early high yield.

When pruning fruit trees in summer in June, it is necessary to balance the growth of all parts, stabilize the tree potential, and remove long branches, competitive branches, pest branches, light blocking branches and sweeping branches.

4 autumn pruning of fruit trees

When pruning fruit trees in autumn, we need to consider the problem of light. Removing shading branches and cutting off new shoots can increase illumination, promote coloring, facilitate flower bud differentiation, increase ventilation and transparency of fruit trees, and lay a foundation for high yield of fruit trees in the coming year.

Summary: The pruning of apple trees has changed the previous pruning in winter. Using modern technology to prune fruit trees all the year round, adjust the structure, adjust the tree potential, clear the road, achieve the purpose of ventilation and light transmission, and lay a solid foundation for fruit trees to blossom and bear fruit and color.
