The ideal season to prune Oaks is November through January. If this is the year to prune, have you scheduled the pruning some time before February 1?
NWACA recommends employing only certified arborists and working with them to develop and execute on an ongoing schedule your Tree Care Plan that implements the Prevent Oak Wilt Best Practices. Avoid uncertified vendors knocking on doors. Do not become the next victim!
