The main purpose of pruning is to improve the tree structure. If the tree is planted close to the structure, you may need to trim it just to give permission.
You only have to prune the trees because removing large branches creates the chance for disease to enter through the wound or simply weakens the tree through removing most of the leaf material. You can hire professionals to get the best tree service in Long Island
Removing or cutting branches is not a safe process, because it requires special equipment and training. To trim the tree correctly, you need to understand how the branch works. During the additional growth process, where the tree produces a growth ring, the branches grow as well.
The point where the branch attaches to the tree is known as the branch skin ridge. In order for the cuts to be as small as possible, you need the last piece not bigger than one third of the stem or branch.
If you pull out the branches, you must do the last cut from the bark to the collar in such a way as to minimize the final wound. If you remove a large branch, you increase the risk of disease. Fungi and bacteria can enter the tree through wounds and cause all kinds of problems.
However, there are exceptions to this rule, such as Maples, Walnut and Birch, all of which bleed sap if cut in spring. For these trees, you must wait for mid-summer or mid-winter pruning.
