Actually, we probably would have had even more peppers and tomatoes if we had found out about copper tape earlier! You can buy this copper tape that goes around the bottom of your pots and it TOTALLY stops slugs from eating your plants.
Over here the slugs are killer, I mean KILLER. They're HUGE and there are tons of them. Sou is too nice to kill them with slug pellets, so we needed a friendly solution.
They really were devastating our plants before the copper tape. And the little buggers don't just eat a pepper/tomato and move on.. NO they take a
little nibble out of every one on the plant! Reminds me of the cartoon Rocket Robin Hood, the opening sequence had Friar Tuck taking a bite from a piece of food, chucking it over his head and biting into the next repeatedly.

Edit: Hmmm, I guess it wasn't in the opening credits. It does show a little of it in the video
here though, at about 36 seconds into it.
