How to grow White Purity Cosmos seeds

Choose Your Planting Method

• Indoors: Start indoors 4-6 weeks before the last frost.
• Outdoors: Direct sow after the last frost, once the soil has warmed.

Prepare Your Materials

• Seed-starting trays or pots (if indoors)
• Well-draining potting mix
• Spray bottle for misting

Sowing the Seeds

• Sow 1/8 to 1/4 inch deep; cover lightly with soil.
• Keep evenly moist until germination.

Provide the Right Conditions

• Light: Bright light.
• Temperature: 68-72°F (20-22°C).

Germination

• 7-14 days.

Transplanting

• After the last frost.
• Harden off before planting out.
• 9-12 inches apart.

Care Tips

• Sun: Full sun.
• Water: Keep moist until established; avoid overwatering and very rich soil, which produce foliage at the expense of flowers.
