Oh, and any other advise or suggestions on how to get around the spring slug and snail assault would be immensely welcome! I've had - well actually more or less anything and everything eaten on previous years by this over-the-wall, annual, overnight invasion. Some very large snails even managed to climb up a lamp-post, along a bracket, past a butchers S-hook and down the chain of a hanging basket in order to get at it's contents!
