How to Kill Off a Rose

in Plants
An unusual question I know but I couldn't get the rose I was intending to give to OH's mum out of the raised beds. The plan is to cut the roots down as far as I can and hope that it dies off as I will be putting new planting in that location. Is there anything I can do to prevent it from growing back? It's a Rosa Primula, and I'm giving some cuttings away so it's not completely lost.

If you live in Derbyshire, as I do.
I don't use weedkillers so have never considered that option.
