Bill,

You'll have to let us know if it works for you. I'm not sure 30 days is long enough, though. (I realize you have to plant by a certain date though.)

Have you ever tried sowing Elbon rye in the fall and allowing it to grow all winter, and then tilling it into the soil in late winter to early spring? It seems to help suppress the nematode population.

I remember the "good old days" when I was just a kid and you could treat your garden with Vapam to kill the nematodes. (Unfortunately it killed everything in the soil.) It was, of course, pulled off the market long ago.

For as much as I complain about my evil, red, hard-as-a-brick clay soil, at least the clay is not a good habitat for nematodes.
