If after many years the tree still has not begun to bear fruit, then you should think about the causes of the problem.
The most common reason is related to the thickening of the crown, as well as the presence of rare and short shoots.
In this case, everything is solved by cutting off excess branches.
After this, the soil near the trunk needs to be slightly loosened with a pitchfork, and manure needs to be added (4 buckets per 1 square meter). The trunk circle needs to be mulched.
The second reason for the lack of fruit may be due to poor tree care.
For example, a deficiency or excess of fertilizers. In the first case, you need to add fertilizer, and in the case of excess, you need to stop adding nutrients for some time.
The third reason why the nut tree does not bloom is the lack of a pollinator.
There are two ways to solve this problem: artificial pollination or grafting a cutting from a tree that blooms at the same time as the walnut tree.
