What to do with cabbage white caterpillars?...
I've noticed that there are a lot of cabbage white caterpillars on my nasturtiums this year. I'm not too bothered about the nasturtiums being eaten but I know the cabbage white is considered a bit of a pest and i'm not sure what to do about them. I am trying to garden organically and for wildlife. Once they have munched the nasturtiums will they move on to other things in the garden? If I just leave them where they are will the birds eat them?
