Marigold Seeds - Nematocidal
$3.25
Tagetes patula
The highest amount of alpha-terthienyl in any marigold available. The trick to good success is to plant just the marigold in your target area for at least 2 or 3 months so the nematodes will only have the marigold to attach to and then die. Late summer blooming. Full sun. Self-seeding annual.

Site Selection
Marigolds are frost sensitive annuals that prefer full sun and tolerate a wide variety of soils, including nutrient poor soils.
Cultivation
Direct sow outdoors in spring once the danger of frost has passed. Seed can also be started indoors 4-5 weeks before the last frost and transplanted outdoors after the last frost date. Sow seeds 1/2" deep and 3-4" apart. Seeds will sprout in 15-20 days. Thin seedlings so that mature plants are 18-24" apart.
