We will always start from the premise that the tree does not need to be pruned. If we prune it or use any pruning technique, it must be done for a reason. For safety reasons, because it can damage the furniture, to make a bonsai, to facilitate the harvesting of fruit, but it will never be an option to do it because everyone does it. A tree does not need to be pruned.
We prune trees and shrubs, we eliminate brush, by hand or with mechanical saw.
