Pruning is the cutting or removing branches or parts of trees or for improving the shape or growth of trees. This is the most common tree maintenance procedure. Usually, trees are pruned preventative or as a corrective measure to remove dead branches, crowded or rubbing limbs, eliminate hazards, and increase light and air penetration. Since each cut to a tree has the potential to change the growth, it is important to educate yourself, considering no branch should be removed without any reason.
