Oak tree dropping leaves in July #802717

Asked July 24, 2022, 11:37 AM EDT

My oak tree leaves suddenly started turning brown and dropping furiously—in the past several days. Could it be related to the drought (I’m in Lake Elmo) or is it possibly the dreaded oak wilt? We lost more than 50 oaks during the 80s and 90s.
