Conditions
Sun
Full sun, at least 6-8 hours a day, for best flowering.
Water
Water regularly, especially during dry periods, keeping the soil moist but not waterlogged. Allow soil to dry slightly between waterings.
Soil
Well-draining, moderately fertile soil. Prefers a neutral to slightly acidic pH (6.0-7.0).
Spacing
French marigolds: 15-20cm; African marigolds: 25-45cm, depending on variety.
Containers
Excellent in pots, window boxes, and borders. Dwarf varieties are particularly good for containers.
Indoors
Can be grown indoors from seed to get a head start, or as temporary houseplants in bright light.
Care and harvest
Feeding
Generally not required in good soil. A light, balanced liquid feed once a month can boost flowering in containers.
Pruning
Deadhead spent flowers regularly to encourage continuous blooming and prevent self-seeding.
Harvesting
Grow in full sun with good airflow and cut blooms to encourage more.
Storage
Best used fresh as cut flowers. Can be dried for potpourri or crafts by hanging upside down.
