Also a good idea is while those vegetables are planted in containers, plant the ground that is infected with nematodes with plants that deters it such as Chrysanthemum or mums, and marigolds.

"Chrysanthemums, particularly the C. coccineum or "painted daisy" species, kill harmful root nematodes in the soil." according to a site.

ediblelandscape: I googled nematodes to see what they were because I haven't had problems with them in Wahiawa, but like the chrysanthemum post above, I read that marigolds may also be effective in killing nematodes. Maybe plant some of them near your tomatoes and other plants in the ground and see how they do.

I tried this with my melon plants, and used rosemary to fend off leaf miner bugs, and that seemed to work. Hope this helps.
