|MadSci Network: General Biology|
My new neighborhood was built on top of heavy clay soil with no vegetation to speak of. I could find no earthworms at all. I amended the soil, planted stuff. A few years later I started finding earthworms. Where did they come from, especially since all my neighbors had the same absence of worms? Do they migrate large distances? Thanks. I couldn't find an answer to this in your database, except to learn that they don't just form out of nothing.
Re: My yard had no worms, then suddenly it did. Where did they come from?
