Tree trimming is the process of cutting back branches and foliage from a tree to promote healthy growth and improve its appearance. This practice helps to remove dead or diseased branches, allowing more sunlight to reach the tree and surrounding plants. Regular trimming can also prevent potential hazards, such as falling branches, especially during storms. Trimming is typically done during the tree's dormant season, which is usually in late winter or early spring. Proper techniques and tools, such as pruning shears and saws, are essential to ensure the tree remains healthy and to minimize stress. Professional arborists often perform this task for optimal results.
