Yes, I know hostas are slug magnets! We didn't plant them and I don't like them much. But we do have hedgehogs so I don't mind keeping them as indirect hedgehog food.
My question is, do they actually attract slugs and therefore endanger everything else, or do they just suck up all the slugs you have already and make them into one nice hedgehog drive through of fat juicy slugs? If they encourage slug rampages, I think I'll dig them out and move them somewhere I can't see them. Otherwise they and the hoggies can stay, especially if they work as a plant shield for everything else!
