Any cover crop -wheat-rye--what every will work with the addition of compost--lots of compost. That will increase the helpful organisms (including fungi that feed on these nematodes) in you garden that will reduce the root knot nematodes numbers. The old farmers in the south would put fresh manure on in the late fall to increase the acidity of the soil and effect the life cycle of these nematodes.

Any Âgreen manure cover crop that is tilled under in the spring while green will help.

Found a good link for your problem.

Thanks, seramas.

Do you have real, live Serama chickens?
I love my Wyandottes.

Yes, about 400. They are kept in small flocks of 50 birds when not individually paired and in breeding cages.
