I have a panel fence between me and my neighbour.
We had ivy on both sides of the fence before we replaced it with new panels. I
appear to have successfully killed the ivy on my side (thanks to suggestions in
this group).

However, my neighbour's has not all been killed off - and new shoots with
leaves are appearing through the fencing on my side.

I have successfully killed all the shoots which come through (Roundup) - but I
wondered if my continued application to new shoots will eventually kill off the
ivy totally?
