- Soil requirements: Marigolds prefer well-drained, moderately fertile soil with a pH level between 6.0 and 7.0. They can tolerate poor soil conditions but thrive best in nutrient-rich soil.
- Sunlight needs: Marigolds require full sun to grow optimally. They need at least 6-8 hours of direct sunlight per day.
- Watering requirements: Marigolds need regular watering, especially during dry periods. Water them deeply once a week, ensuring the soil remains moist but not waterlogged. Avoid overhead watering to prevent fungal diseases.
- Planting season: The best time to plant marigold seeds is in the spring after the last frost has passed. They can also be started indoors 6-8 weeks before the last expected frost date.
- Depth and spacing: Plant marigold seeds about 1/4 inch deep and space them 6-12 inches apart, depending on the variety. For larger varieties, increase the spacing to 12-18 inches.
- Germination time: Marigold seeds typically germinate within 5-7 days under optimal conditions.
- Maturity time: Marigolds usually reach maturity and start blooming within 8-10 weeks after planting.
- Harvesting time: The best time to harvest marigold flowers is in the early morning when the blooms are fresh and fully open.
- Harvesting tips: Use sharp scissors or pruning shears to cut the flowers. To encourage continuous blooming, deadhead spent flowers regularly. Store harvested flowers in a cool, dry place if not used immediately.
