Just in case anyone is under the impression I never have any problems in my little garden... I present evidence to the contrary!
I think a little slug got into the cold frame. One day there were happy sweetpea seedlings, the next day .. there weren't!! (Its OK, I had a couple more which I rescued in time.
Otherwise, everything in the garden is doing well, as far as I can tell. I really like the variegated apple mint foliage, the chives are just opening and the herbs are generally verdant.
