just might have to start up with a worm bin or two again sometime. I know the castings are great for the plants. You don't live too far from me Becky -- and I don't find earthworms in my gardens at all; no matter how much I amend. I'm envious that you are finding them and wondering how they got started.
My understanding is that chitin repels nematodes. I don't think there is anything that will kill them -- even solarization doesn't quite do it as they just go deeper. But anything you can do to make their environment more unpleasant for them is better than nothing. We know they don't like rich soil -- so just amend, amend and amend -- and amen to that !
