I have about 100m of ground that was under 3 very large trees to cultivate. Currently, there is considerable ivy growing in it which I'm attempting to dig out, having first sprayed the leaves with concentrated Roundup. I have 2 queries about the next steps.
1. Is there any point spraying Roundup directly onto exposed ivy roots (i.e. those I've dug up and exposed but there are too many to easily totally remove)?
2. If I break up ivy roots via a rotavator, will each section potentially regrow as a new plant?
