We should follow the laws of nature, slowly adjust the fruit trees and manage them from light to heavy according to their age.
According to the size of your yard, it is a common practice to crown annual seedlings at a certain height, usually 70-80 cm above the ground.
After pruning, the upward branches are left, which is convenient for the management of the second floor in the second year, and so on. Generally, each layer has three naturally open lateral branches, and the overlooking angle is 120 degrees, which do not overlap each other.
Finally, we must control the height of the tree and make it grow horizontally as much as possible, as shown below.
The method adopted on the right side of the above picture is pruning and shaping to make the lateral branches of fruit trees grow horizontally as far as possible, so as to obtain the best ventilation and lighting conditions and control the height of trees. The above figures are all theoretical figures. In fact, due to improper management, fruit trees grow in a mess. As long as we prune according to the following principles, fruit trees will gradually become theoretical models.
Remove branches that grow vertically upward, branches that grow toward the tree core, appropriate lateral branches to keep the previous branch growing forward, branches that grow underground, branches that grow parallel to the lateral branches, and small branches on the main branch. That is to say, remove long branches, wandering branches, competitive branches, downward branches and parallel branches. Finally, cut the remaining front branches by one third to form the short fruit branches of that year.
