Cockscomb Growing (Celosia cristata) from seeds is a straightforward process. Cockscomb is known for its distinctive, velvety blooms that resemble a rooster’s comb. Here’s a step-by-step guide to help you grow cockscomb from seeds:
1. Seed Selection:
- Choose high-quality cockscomb seeds from a reliable source. There are various cultivars with different colors and sizes, so select the one that appeals to you.
2. Starting Seeds Indoors:
- Start seeds indoors 6-8 weeks before the last expected frost in your area. Use seed-starting trays or small pots with a well-draining seed-starting mix.
- Plant the seeds about 1/4 inch deep and lightly cover them with soil. Water the soil thoroughly.
3. Germination:
- Place the seed trays or pots in a warm location with temperatures between 70°F to 75°F (21°C to 24°C) for germination.
- Cockscomb seeds typically germinate within 7-14 days. Once the seedlings emerge, thin them to leave the healthiest ones.
4. Transplanting Seedlings:
- Transplant the seedlings outdoors after the last frost has passed and the soil has warmed up. Choose a sunny location with well-drained soil.
- Space the plants according to the specific requirements of the chosen cultivar, usually about 12-18 inches apart.
5. Outdoor Care:
- Cockscomb thrives in full sunlight, so ensure they receive at least 6-8 hours of direct sunlight daily.
- Water the plants regularly, keeping the soil consistently moist but not waterlogged.
6. Soil and Fertilization:
- Provide well-draining soil enriched with organic matter. Incorporate compost into the soil before planting.
- Fertilize with a balanced, all-purpose fertilizer at the time of planting and again during the growing season.
7. Support:
- While some cockscomb varieties are compact, others may benefit from staking or support as they grow to prevent the heavy flower heads from bending or breaking.
8. Deadheading:
- Deadhead spent flowers regularly to encourage continuous blooming throughout the season.
9. Pests and Diseases:
- Cockscomb is generally resistant to pests, but keep an eye out for issues such as aphids or spider mites. Treat as needed.
- Good air circulation can help prevent fungal diseases. Water at the base of the plant to avoid wetting the foliage.
10. Harvesting Seeds:
- If you want to save cockscomb seeds for the next season, allow some flowers to mature on the plant. Harvest the seeds when the flower heads have dried and turned brown.
