You do need to get the roots and but for now, you can keep cutting, and stay on top of it. It may still be getting energy (chlorophyll) from other parts that you can't see since you don't know where the plant originates from.

An alternative is to take one of the vine sections and stick it in some herbicide in a container. That way, you only affect that vine. Leave it in there for a few days.

You may have to repeat the procedure over the season or even for a few more years to come, but hopefully it helps to get the herbicide back to some of the originating roots.

That's great thankyou. I've always hated Ivy. And know I remember why!

Thanks for your help.
