Shaping a tree to reflect its growth pattern and the landscape of the surrounding area helps promote a healthier and safer environment. Pruning is the most common tree maintenance procedure. It should be performed with an understanding of how the tree responds to each cut. Improper pruning can cause damage that will last for the life of the tree, and it can even shorten the tree’s life.
Because each cut has the potential to change the growth of the tree, no branch should be removed without reason. In most cases, mature trees are pruned as a corrective or preventative measure. Trees produce a dense crown of leaves to manufacture glucose used as energy for growth and development. Removal of foliage through pruning can reduce growth and stored energy reserves. Most routine pruning to remove weak, diseased, or dead limbs can be accomplished at any time. As a rule, growth is maximized and wound closure is fastest if pruning takes place before the spring growth flush. Avoid heavy pruning immediately following this spring growth; at this time, the trees have just expended a great deal of energy to produce foliage and early shoot growth. Removal of a large percentage of foliage at this time can stress the tree. The amount that should be removed depends on the size, species, and age of the tree.
Pruning trees can be dangerous. If pruning involves working above the ground, around power lines or using power equipment, it is best to hire a professional arborist. A professional arborist has the knowledge and equipment to prune your trees safely, and can determine the type of pruning necessary to improve the health, appearance, and safety of your trees.
Each city has its own bylaws. Please refer to your city’s website for more information. No one may prune the branches or roots of a significant tree or any tree within a tree retention area without first obtaining a tree cutting permit.
