🗓️ When to Sow

  • Indoors: Start 4–6 weeks before last frost.

  • Outdoors: Sow directly after the last frost, once soil warms (above 15°C / 60°F).


🌱 How to Sow

Option 1: Direct Outdoor Sowing (Recommended)

  1. Prepare Soil

    • Choose a site with full sun and well-drained soil.

    • Cosmos tolerate poor soil but dislike overly rich, wet conditions.

  2. Sow Seeds

    • Depth: ¼ inch (6 mm).

    • Spacing: Sow thinly, then thin seedlings to 12–18 inches (30–45 cm) apart.

  3. Watering

    • Water gently after sowing.

    • Keep soil moist until seedlings emerge (but not soggy).

  4. Germination

    • Time: 7–10 days

    • Ideal temperature: 65–70°F (18–21°C)


Option 2: Indoor Sowing

  1. Use pots or seed trays filled with light seed-starting mix.

  2. Sow seeds ¼ inch deep.

  3. Keep moist and warm (65–70°F) until germination.

  4. Provide bright light once seedlings emerge.

  5. Harden off seedlings before transplanting outside.


🌿 After Germination

  • Thin or transplant to 12–18 inches apart.

  • Cosmos grow quickly and bloom around 60–75 days from sowing.


🌼 Growing Notes

  • Sun: Full sun (6+ hours/day).

  • Soil: Light, well-draining; avoid high-fertility soil to prevent leggy growth.

  • Water: Drought-tolerant once established; water during dry spells.

  • Deadheading: Prolongs blooming, but can also allow some to go to seed for self-sowing.

  • Height: 'Sensation Radiance' can grow 3–4 feet (90–120 cm) tall — may need staking in windy areas.
