Barrier for English Ivy?
Does anyone know how deep a barrier must be to block the spread of English Ivy? I know the roots are quite shallow, but wonder if they "dive" if challenged.
My neighbor has his entire wooded back yard rampant with it and I'm just sick and tired of having to pull out the vines along the property line. Due to the loss of a 60' oak during Sandy, shade patterns have changed, so I will be re-doing that part of the yard and while I'm at it, considered installing a barrier.
Thanks for any advice.
