When and Where to Plant Cosmos Seeds
Cosmos are sun worshippers through and through. Plant them in full sun and average, well-drained soilno need for rich amendments; these beauties bloom best when you keep it simple. Sow seeds directly in the garden after the last spring frost, once soil temps reach 60°F. Scatter seeds gently and press them into the surface (they need a little light to get growing). With a bit of moisture and patience, seedlings will appear in 5 to 10 days. Want a head start? Start seeds indoors 4–6 weeks before your last frost and transplant once the weather’s warm and welcoming. For a step-by-step guide, check out our blog: How To Grow Cosmos.
Caring for Your Cosmos Flowers
Low-maintenance and high-impact—Cosmos are the dreamers of the garden that ask for little but give so much. Water only during prolonged dry spells, and go easy on fertilizer (more food means more leaves, not more flowers!). Keep the blooms coming by deadheading regularly, or let them self-sow for a spontaneous encore next season. Taller varieties might need a little support when the wind gets feisty. With just a bit of love, your Cosmos will paint the garden with color and keep pollinators partying all summer long.
