Description
The Nematode Marigold (Tagetes patula var. nana) is more than a cheerful summer flower: its roots exude substances that specifically repel wandering root‑nematodes in the soil. As a densely sown green manure, the low varieties rehabilitate infested beds throughout an entire season. The orange‑red blooms continuously attract hoverflies and bees.
Care instructions
Sow the marigold from mid‑May (week 20) after the last frost over a wide, dense area in the garden, or start indoors on a windowsill in April. Keep the soil evenly moist and allow the crop to remain until autumn – only a closed, long‑lasting marigold cover fully activates its nematode‑repellent effect. Incorporate the plant after the first frost.
