It seems the battle is starting again, I have just picked off a green caterpillar from a surviving geranium in the raised flower bed this afternoon. Also slugs are starting to crawl out from under folliage, etc. When I find a slug in its shell I chuck it on the lawn and the crows then pick it up and proceed to bash it on the roof of my house. I dont know whether to like crows or not as they make a racket and can damage the tiles. Maybe the best thing is to grow plants and flowers the slugs dont like, such as Flag Irises, Bergena, rock roses, etc. But they will eat anything given the chance. I am going to put lots of tins containing beer around the place and drown the pests.
