Seedling
2-3 weeksSmall green seedlings with cotyledons and initial true leaves appear within 5-10 days of germination.
Maintain consistent moisture without waterlogging. Provide bright light. Thin seedlings to prevent crowding.
Vegetative
3-4 weeksPlant develops sturdy stems and increasingly bushy foliage with feathery, finely-divided green leaves characteristic of marigolds.
Pinch back growing tips when 4-6 inches tall to encourage bushier growth and more flowers. Water moderately. Begin light fertilizing.
Budding
2-3 weeksFlower buds begin forming at branch tips; tightly closed buds swell and show golden color beneath the sepals.
Maintain consistent watering and fertilize every 2 weeks with balanced or slightly higher phosphorus fertilizer. Remove any yellow leaves.
Flowering
4-12 weeks (or until frost)Fully double, golden-yellow flowers open with many tightly-packed petals forming pompom-like blooms; flowers reach 2-3 inches across.
Deadhead spent flowers regularly to encourage continuous blooming. Water at soil level. Monitor for pests. Maintain fertilizer schedule.
Decline
Variable; until frost or end of seasonAs temperatures cool in autumn or if plants are not deadheaded, flower production slows and plant vigor decreases. In frost-free zones, plants may persist.
Remove spent plants after frost in cool climates. In warm zones, allow some flowers to set seed if desired for self-sowing next year, or continue deadheading to prolong bloom.

Harvest Tips
For cut flowers, harvest in early morning when blooms are fully open but still fresh. Cut stems just above a leaf node. Place immediately in water. Double Gold flowers last 7-10 days in a vase. For deadheading, pinch or snip off spent flower heads just below the bloom to redirect energy to new flowers.
