Digging out ground elder
I have ground elder in a relatively small border contained by sleepers (ground elder present, I believe, by using contaminated compost), I used herbicide in the sprint and that worked well to just leave small bits now.
Can I dig out the soil and replace with new. And if so, how deep would I need to dig?
I plan to put the 'contaminated' soil beneath an area of ground that I need to build up. It will be turfed and regularly mown.
Need to get plants planted (currently sitting in pots) so don't really want to commit to another year of herbicide.
