Walnut cutting

Walnut cutting.

Walnuts make up loose, regular crowns, therefore they rarely need pruning. In Poland, nuts are planted mainly in farmyards, where high-stemmed forms are more practical than low-stemmed or bushy ones. Young nut trees need to be trimmed to height 1-1,5 m, to get the trunk of the required height. Older walnut trees are usually only cut then, when one branch or the other located too low interferes with the passage of people or farm animals under the trees. The cut should be made in February or August. The branches should not be cut in spring, because after spring cutting, there is abundant discharge of juice from the wounds, the so-called crying that facilitates the development of pathogenic fungi.
