Major commercial species and varieties
- African marigold (Tagetes erecta): Tall, robust plants bearing large, globular yellow, orange, and golden flowers; popular commercial varieties include Pusa Narangi Gainda and Pusa Basanti Gainda.
- French marigold (Tagetes patula): Dwarf, bushy plants producing abundant small yellow, orange, or bi-colored reddish blooms, ideal for bedding and short garlands.
- F1 commercial hybrids: High-yielding uniform hybrids preferred for commercial loose-flower cultivation due to dense, heavy flower heads.
Nursery management and cultivation practices
Marigold seeds are sown in raised nursery beds and transplanted after 25 to 30 days when seedlings reach 10 to 15 cm in height. Spacing is maintained at 40 cm x 40 cm or 60 cm x 60 cm depending on plant vigor. Terminal shoot pinching at 30 to 35 days after transplanting is essential to stimulate profuse lateral branching and maximize the number of flower buds.
Harvesting and mandi marketing
Flowers are harvested when fully opened in the cool morning or late evening hours. Pack fresh blooms in ventilated gunny bags or bamboo baskets for same-day delivery to local flower mandis, particularly aligning harvest flushes with major festival seasons.

Common questions
Why is terminal pinching important in marigold cultivation?
Pinching removes the central shoot tip, breaking apical dominance to stimulate lateral branches and produce significantly more flower buds.
What is the nursery duration for marigold seedlings before transplanting?
Seedlings are ready for field transplanting within 25 to 30 days after sowing in nursery beds.
How does marigold farming benefit soil nematode control?
Marigold roots release alpha-terthienyl, an organic exudate that suppresses harmful plant-parasitic root-knot nematodes.
