The reason for the infection of fruit trees is not weak immunity, but improper care of garden crops.
As for trees, fungus and other infections attack wood as a result of improper pruning. Here's how not to do sanitary or rejuvenating pruning.
The main mistakes in caring for an apple tree are not pruning at all or trimming the tree with rare diligence.
In the latter case, the apple tree may not only get sick, but also not recover from the stress it has received.
And if you do not prune at all, then over time the yield will decrease, because timely and competent pruning helps to rejuvenate the tree.
Trimming Mistakes
1. Often, due to lack of experience, gardeners violate the main rule, namely, they try to cut off everything unnecessary in one go.
According to the rules, rejuvenating pruning is carried out over several years, i.e. over 2-3 seasons.
In one year, you can cut off no more than 1/4 of all the green mass on the tree, otherwise stress cannot be avoided, and the tree may die.
2. Do not plan to perform rejuvenating pruning in winter. At this time, you can perform sanitary pruning, and postpone the rejuvenation procedure until spring.
