I'm just asking because i was chatting with my mom and she told me how my dad used to deal with them in his garden. He used to buy those copper scouring pads from the hardware store and unravel them and make a ring(fence) around the plants at the base, about 6 to 8 inches out from the stalk. She said once he did that, he never had snail problems again. Just thought i'd share that one with you all.
