I'll freely admit, it's nice to have some leeway with crops - if your spring crop fails, put in a midsummer one!

Well, all the seedlings are still there instead of munched down... Mind you, I haven't spotted too many slugs and snails around this year. I don't know if it's just not quite the right weather (although one would think cold and wet would do it, right?) or if they're just waiting, biding their time before they burst out and eat everything in my garden. It wouldn't surprise me.

Anyway, the logic of it makes sense to me - slugs and snails like non-sharp surfaces, and ground up eggshells are most definitely edged...
