|Pruning oaks in spring can cause oak wilt: DNR|
The Wisconsin Department of Natural Resources (DNR)?recently released a statement informing the public that pruning oak trees from April through July can make them vulnerable to oak wilt, a fatal fungal disease of red oaks.
The risk of oak wilt moving from one tree to another is highest April through July, said DNR?officials.
In fact, homeowners should take special care and avoid wounding oaks in any way during those months, according to Kyoko Scanlon, the DNR’s statewide forest pathologist“Any action that provides an opening into the tree, such as carving initials into the tree, accidentally cutting exposed roots with a lawn mower or attaching a bird feeder or clothes line, could provide an opportunity for the oak wilt fungus to invade and establish itself in the tree,”
