Got oaks?
Now is the best time to prune them!
The trees are in dormancy and itβs an easier time to see branch structure β plus, pruning now avoids the risk of oak wilt infection.
Oak wilt is a non-native fungal disease that can be deadly to all oak species. It is spread by sap-feeding beetles that become active in warm weather. These tiny beetles are attracted to fresh wounds on trees (like those made from pruning) and can carry oak wilt spores with them from infected trees.
You can help stop the spread of oak wilt in Minnesota! Protect your oaks by pruning or cutting now. And please donβt prune between April - July, when risk of spread is highest.
