We are about to move home to a house which has been unoccupied since May. The garden needs a tidy bit I noticed when I popped over yesterday (we own it now just waiting to move in a few weeks and doing some odd jobs) that there’s a gorgeous trellis up the side with some lovely climbing roses. I want to keep them next year but they’re obviously dying now. Do I dead head them? Let them fall? How can I preserve them?
