What you do depends quite a lot on what you want to end up with there - are you aiming for a path through a wildlife area, a lawn, something else?
Btw those nettle leaves are young enough that you can put on some gloves and make soup with them...
Also, I'm curious, is it cow parsnip (which is North American I think) or giant hogweed or cow parsley?
