How to grow Radio Calendula seeds

Choose Your Planting Method

• Indoors: Start indoors 4-6 weeks before the last frost.
• Outdoors: Direct sow in early spring once the soil reaches 60°F (16°C); calendula tolerates light frost.

Prepare Your Materials

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

Sowing the Seeds

• Sow 1/2 inch (1 cm) deep and cover — seeds germinate best in darkness.
• Water in well after sowing.

Provide the Right Conditions

• Light: Bright light after germination.
• Temperature: 60-65°F (16-18°C) is ideal for germination.

Germination

• Germination takes 5-15 days.
• Thin or transplant when seedlings have 1-2 true leaves.

Transplanting

• Transplant after the last frost, or set out in cool weather once hardened.
• Harden off if started indoors.
• Space 12-16 inches apart in well-drained soil.

Care Tips

• Sun: Full sun; appreciates a little afternoon shade in hot climates.
• Water: Water regularly until established; do not overwater.
• Fertilizer: Average soil is fine — rich soil is not needed.
• Deadhead faded flowers regularly to keep blooms coming; plants may pause in extreme heat and resume in fall.

Bloom Time:

Late spring to fall, starting about 60 days from sowing.
