Jane -- I'd like to be as gleeful about what the frosts are doing to pests as you are, but sadly I'm not! I came in an hour ago from the veg. plot with a good crop of caterpillars off my sprouts, [both the "camouflage green" + the black/yellow striped varieties] and the some of the beasts 11/2inces long. We've had a few frosts here in Norfolk to -3deg., and snow, but they are just as lively as 3 months ago. I've been gardening for over 50 years, and can't remember a year like it! (Picked outdoor strawberries on 2nd Oct., and [unheated]g/house beefsteak toms on 17th Nov. - it must be this "climate change"]
If I knew how, I'd post a couple of pictures ----- ,
It'd be nice to have a REAL winter this time! We can wish!
