There are three reasons why trees need to be pruned and trimmed: beauty, health and safety.
• Beauty – To help a tree keep its proper shape and look, pruning is needed. Refrain from doing unnatural shapes that may cause damage to the tree’s growth.
• Health – One may be able to save an infected tree if it is properly pruned. You can thin the crown of the tree to aid in better airflow, and any branches that rub or cross each other should be trimmed to prevent them from decaying and breaking off.
• Safety – it’s always a potential danger when a tree has died or broken branches that could fall at any moment. Any branches preventing you from seeing properly while driving should be trimmed back. Also, if there are branches dangerously close to utility poles and lines, you may want to call your local utility company to take care of trimming the trees.
