ground elder

[tess]

Hi all, I’m in the process of setting a new veg bed up. When we moved here about a year ago I spread old carpet over the veg bed area which was mainly Bramble and ground elder. I’ve sourced some local compost&manure now so was aiming to create raised beds with 15cm of the lovely stuff. Do I need to dig over the ground first once I’ve removed the carpet and remove any roots of ground elder or would the compost suppress it enough? Many thanks for any advise. Kind regards Tess
