Rr_Salmander could use some advice:

A couple days ago, my neighbor told me that the tree which I thought we shared was really on my property and that it was a "trash tree" (a Mulberry tree). He suggested I cut it down. Here's my weighing of the issue. Can you help me with some learned advice? Is my neighbor right and, even if not, wouldn't poison be bad for the local environment anyway?

What do you think? Weigh in here.
