There is much more to proper tree trimming than meets the untrained eye. Knowing just how and when to trim branches and overgrowth is imperative to healthy regrowth. Cutting into a tree’s trunk is one of quickest ways to lessen its strength. Inexperienced crews may lop off a branch flush with the trunk, removing what is called the tree collar. If removed, the tree will have difficulty in healing, leaving a gaping wound where disease and insects can invade and grow.
Furthermore, timing is extremely important. The middle of a hot summer is never the optimal time for tree trimming, nor is the dead of winter. Trees have to fight too hard for survival during the extreme weather seasons and cutting their limbs and branches during these times just gives them more negatives to spend needed energy on. Most trees do better with pruning and trimming in the milder seasons. Unless you’ve got a broken branch that is a safety issue, make sure to wait until the fall or spring for best results
