My neighbor has a tree with a big surface root
coming under the fence, and into my yard. My
neighbor could care less about the tree, and
expressed an interest in getting rid of the tree.
The surface root is raising the fence and Iwant to
retard the growth of this root so it does not bust
the fence. Can I drill some holes into the root and
pour something in it to kill the root and the tree...

what would work??? thank you in advance
