Question From: T. RENNE - Big Rapids, Michigan, United States
Q: I HAVE A MOUNTAIN ASH AND WOODPECKERS HAVE DRILLED HOLES ALL THROUGH THE TRUNK AND BRANCHES THE TREES ARE NOW LEAKING SAP
It is best not to try and treat the holes. If it were my tree I would have a certified arborist do an on-site inspection. Your tree may be badly infested insects. To find a professional on your area go to www.tcia.org and enter your zip code. Best Nancy
