How and when to prune a walnut


Good day!

Tell me, please, how to prune a walnut? The tree is 5 years old and, unfortunately, the variety is not known (from a neighbor on the site of the protein I made reserves that have sprouted, he shared a seedling with us). The nut has not yet borne fruit. Thanks in advance for your reply.

Answers:

The young seedling begins to do pruning from 1-2 years old, in the spring (April) after reaching 1.5-2 m. This is done to form the stem and subsequently the crown from it. The last formation is made in the spring of 4 years of growth. Since time is lost, I will not explain where and how it was necessary to trim. Forks with sharp corners have already formed on your tree, and skeletal branches have grown too long. At the same time, they are poorly covered with lateral branches - this is the consequence of pruning not done on time. If the crown is not formed, then the fruiting shoots die off, as a result of which the yield of the tree.

Now the tree will have to be “shredded" strongly; otherwise, after a period of 7-10 years, the tree will grow even larger with an ugly wild crown. In this case, there will be few lateral branches and fruiting shoots.

What to do: in the summer (end of July) you can cut only branches that grow inward, nothing else can be done. Pruning for the crown will have to be postponed for 6 year growth, in the spring (end of April). When forming the crown, all skeletal branches are cut each through one, in a circle around the trunk, in the end, only 4-5 skeletal branches remain on the 4-year-old tree after trimming. In your case, you need to leave 7-8 skeletal branches.

First of all, remove all skeletal branches growing at right angles (less than 45 degrees). If you do not remove them, they still break off later. Pruning is done, leaving 2 buds on each branch. These buds in the year of pruning by the fall will produce 1-2 branches. If these two kidneys are the first from the stamp (the central trunk) have already given small shoots, leave them, cut them higher. At the same time, make sure that these shoots do not grow at right angles. Those that are cut at right angles (called forks) are useless branches. The crown of the central trunk is also subject to pruning.
