Identifying what limbs to cut can be one of the most difficult parts of pruning a tree. I discussed the three reason’s why to prune trees in volume 1 of my pruning series: for tree health, cosmetics and structural integrity. However, many times these different reasons would lead you determine that different limbs need to be pruned. Balancing these priorities is where experience and an artistic eye really comes into play. Different people will often come to different conclusions. While weighing your priorities for pruning there are a few general rules you can follow to help error on the side of benefit for the tree.
