When should a madrone be cut down?
We have a madrone in our front yard. The diameter is just over 24 inches near base of the tree. It has two "holes" near its base. When I say holes, I mean that both the bark and a lot of the wood behind the bark is missing. Also, the missing wood slants downward and the 2 holes join together.
Thank you for including an image with your questions. In some instances, a landscape tree with large holes may still be structurally sound. But a decision concerning safety can only be made following an on-site evaluation by trained persons. I suggest you request such as evaluation by several Certified Arborists. It will be helpful if those Arborists are trained in evaluating potentially hazardous trees.
