Our beloved oak trees should never be trimmed during the summer months. This is because oak trees have a disease called Oak Wilt, which is spread by pests and could infect and even kill oak trees that are trimmed between April and October. Always wait until the fall and winter to trim oak trees. However: Sometimes tree trimming in summer is unavoidable. If you encounter one of these scenarios, it’s okay to bend the rules and trim your trees during the summer months:
While we love trees and want to take the best care of them that’s possible, human safety always comes first. Sometimes, a tree limb will be hanging so low that it’s dangerous. It may be hanging so low that it impedes your ability to walk around or under it for example. In these cases where safety is compromised, tree trimming in the summer is not only justified, it’s needed.
