Conundrum - To spray or not
hello, I wonder if anyone can help me with a little problem. I have a well established Berberis that I moved quite a few years ago. It's growing well but over the last two years when it's in full leaf, it gets decimated by a horde of tiny caterpillars which I think are Cabbage Whites. I don't usually spray my plants with anything because I don't want to harm the bees/butterflies/hoverflies as they're in enough trouble as it is. However, I wondered if there's another solution to stopping the caterpillars from munching my shrub ?? Something that won't harm the other beneficial insects ??? Think i'm clutching at straws really but thought i'd ask anyway !!!!
