Snails in the potting soil?
I was just transplanting a fern out of a large pot it didn't seem too happy in, and noticed there were quite a few large snails in the soil. Could they damage the plant, such as eating the roots? I was planning on dumping the soil in the compost, but don't want to spread the snails if they're damaging anything (I think I must have mixed some compost into the potting soil, which is how the snails may have gotten there). I'm used to ants in the pots, but never seen snails.
