🌱 How to Grow Sea Shells Cosmos Mix from Seed
1. Seed Preparation
Cosmos seeds do not require stratification or soaking, but light scarification (gently rubbing with sandpaper) can help speed up germination.
Use fresh seeds for best germination results, ideally within 1–2 years of harvest.

Germination Time: 7–14 days
Light Requirement: Lightly cover the seeds—no more than 1/4 inch of soil.
3. Planting Instructions
Direct Sow: Best sown after the last frost in spring directly into the garden.
Indoor Start: Start seeds 4–6 weeks before the last frost date, then transplant after hardening off.
Space seeds 10–12 inches apart, or thin seedlings to that distance once sprouted.
Ensure the site receives 6+ hours of full sun daily.

Deadhead spent blooms to encourage continual flowering.
Tall plants may require staking in windy areas.
