Oak Trees

Oak trees are a popular shade tree in the area, and care should be taken to prevent oak wilt. April marks the time oak tree pruning should end in order to avoid this fatal oak disease. If you need to cut a living branch or remove an oak tree from April through October, it's important to spray the pruning cut or top of the stump immediately with latex spray paint.

November through March is the best time to prune oak trees. This is actually true for most trees, since insects and diseases are not active. Get more information on oak wilt from University of MN Extension Service.
