Which of the following is a common mistake when pruning trees?

Over-pruning, or removing too many branches, is a common mistake that can have significant negative effects on a tree's health. When excessive branches are removed, it can lead to stress, decreased vigor, and increased susceptibility to disease and pests. Trees rely on their foliage to photosynthesize and produce energy; removing too many branches diminishes their ability to do so. Additionally, it can alter the tree's natural shape, leading to structural imbalances and potentially causing issues with the tree's stability over time. Proper pruning practices involve understanding how much to remove and when to do it to maintain the tree's health and encourage strong growth. Those who prune trees should be well-informed about the specific needs of the species they are working with to avoid the detrimental effects of over-pruning.
