Root-knot nematodes are common pests of many vegetables and flowers. Marigolds can be effective against them as a trap crop by planting them as a cover crop and then tilling them into the soil as green manure. In areas with short growing seasons, they should be planted in the previous season or 3-4 months before planting vegetable crops. Sow 1oz. per 1000sq. ft.
