GROWING METHOD OF MARIGOLD AFRICAN DOUBLE:
Planting Distance: 30-45 cm apart in flowerbeds or 25 cm pots.
Watering: Water the marigold plants twice a week in winters, every alternate day in summers. Provide plenty of water to potted plants as well.
Feeding: The African double marigold needs well manured and moist soil. The soil should be cultivated well, and a good dose of cow dung manure (8-10 kg per square meter area) should be incorporated into the soil to obtain double flowers in abundance.
Plant care: Marigolds are hardy plants and are rarely attacked by diseases. In poorly drained soil, footrot caused by Phytophthora may occur. Prophylactic spray or drenching with Blitox is helpful in checking the foot rot.
Bloom time: 2.5-3 months after sowing of seeds.
Pinching: The seedlings tend to produce flower buds at a comparatively young stage. These should be pinched off to obtain bushy and compact growth.
