As I was claering the space from last year's runner beans, I found that the roots had survived the winter and are putting up new shoots.
As you can see, not very spectacular, but it's there! I'm reluctant to dig it up, and have decided to leave it, plant this year's as planned, and see what happens, but I was wondering if anyone else has experience of this? I'm on the southern edge of Dartmoor if that's of any interest. I've already mentioned this on the 'May in your garden thread', apologies for reposting but thought I might get a wider audience if I posted as a new topic.
