In order to avoid my lettuce seedlings becoming gourmet slug fodder, some action is needed. My first method of defence involves plastic bottles turned into cloches, and smeared with a ring of Vaseline, which apparently the slimy creatures find disgustingly slimy and won’t go near. Maybe they think it’s the slime trail of some other strange mollusc that smells odd and is best avoided? The cloches will also keep in a bit of warmth and protect them from the elements. Just be sure to push them really firmly into the ground so they don’t blow away. Some people push a small cane or stick through the hole and into the ground to anchor them, but I’m not sure it’s necessary.
My second (experimental) method of defence, is dried crushed chillies. Just because I ran out of bottles. The slugs obviously haven’t developed our continental taste for the hot stuff, as they’re quite repelled by it. They say coffee grounds also have the same effect, though I haven’t tried them. It’s only been a week, but so far non have been touched. I realise I may end up with chilli plants popping up everywhere, but I can easily weed them out. I’ll let you know how they get on.
