Because each cut has the potential to change the growth of the tree, no branch should be removed without a reason. Common reasons for tree pruning include:
- To remove dead branches
- To improve form
- To reduce risk
- To increase light and air penetration
When to Prune
Most routine pruning to remove weak, diseased, or dead limbs can be accomplished at any time during the year with little effect on the tree.
When Not to Prune a Tree
A few tree diseases, such as oak wilt, can be spread when pruning wounds provide access to pathogens (disease-causing agents). Susceptible trees should not be pruned during active transmission periods.
