The Q&A Archives: Sugar Maple Trunk Holes

Question: I have a sugar maple near the house which has several small holes on its trunk. Any ideas what could be causing this?

Answer: There are many possible reasons for holes in a tree, ranging from a borer insect to decay at the site of a fallen branch to interior deterioration. In general, holes are not a positive sign and may be an indication of a more serious problem. They should be examined by a professionally trained and certified arborist, or possibly discussed with your county extension (696-3500). I do hope it is nothing serious.
