Q

My neighbors Aspen trees are sending roots into my yard. Is there anyway besides a barrier to discourage this growth?

Answer(s)

A

Aspen trees in nature grow by root suckering. Aspen are fast growing trees and propagate through root suckering. This is a common landscape problem with aspen trees because root suckers comeup in lawns, flower beds and anywhere that is available for trees to develop.  There is not easy solution for this other than cutting out the suckers as soon as you see them.  This is a maintenance issue, similar to weeding.  There is and expensive and labor intensive possibility as you mentioned of digging down and placing a root barrier, which is not a guarantee of roots moving around or under the barrier.  I do warn against using a chemical herbicide, because the roots are connected and possible translocation of the herbicide could move into your neighbor's tree and you could be held liable for "killing" their tree.

Best solution is using pruners, string trimmer, lawnmower to keep the suckers from those suckers becoming small trees and getting too large and becoming more difficult to remove.

Good Luck
