I live in a fairly wet climate (the Netherlands) and there's a hedge around my garden ... so: there are many snails here. =( I started a herb spiral this spring, with also some vegetables in it. But already three cabbage plants and the parsley are all eaten by the snails. What could I plant in that spiral to chase away the snails? Someone said: they don't like garlic. Is that true? And what more? Please give official Latin names, I don't know all English names.
