Questions of the Week:

I’m about to put an addition on my house that will require a foundation being built approximately six to eight feet from a well-established maple tree that’s about 30 to 40 feet high. The builder says there’s a chance the tree will die when the roots are cut during trenching. Is there anything I can do to help increase the tree’s odds of survival? Many thanks,

Do I really need to mulch around my trees or is it just a matter of aesthetics? I don’t like the ‘mulched circle’ look around the base of trees, so when I planted mine about twenty years ago, I just let grass grow up to the trunks. It looks natural. But recently a tree trimmer said that my trees looked “dry” and that I should dig out the grass and mulch them. Sounds crazy to me. What do you think?
