When I buy a snail in a shop (already grown in a pot) and leave it at home, I always miss it. It starts to thin and then goes completely. I can't put it outside the window, because we live on the ground floor and someone already stole 2 boxes from me. So I have to grow it at home in the apartment. Do you think that if I buy a seed and plant it in a flower bed, it will last me? The one from the mall always leaves.
