Pruning and thinning is important to help maintain the over all health and preservation of any tree. The primary purpose is to remove dead, damaged and diseased branches to help prevent insect infestation and decaying organism from entering the tree.
Thinning allows air and sunlight to flow freely through the canopy to help it properly grow. Pruning of trees also includes removal of weak wood, crossing branches, and co-dominant leaders that can lead to the tree being damaged in heavy winds. Correct pruning procedures maintain a strong tree structure preventing safety hazards such as low growing branches that can cause damage to pedestrians and cars.
