The only steps we can control in the oak wilt infection process are:
Consider not pruning your oak trees. Pruning of oaks is solely for cosmetic purposes and provides no health benefit to the tree. “Pruning up” an oak tree (removing the lower and inner branches) is actually detrimental to its health.
Always immediately paint all cuts and injuries to all oaks in all seasons.
Do not buy or move firewood from trees that have recently died of oak wilt. The fresh wood can be infectious until the wood has dried for several months.
Thank you for taking these precautions with your oak trees. We hope that these steps will enable you and all of our other homeowners to enjoy our majestic oak trees on the Ranch for many years to come.
