How to grow Greenheart Orange Calendula seeds

Choose Your Planting Method

• Indoors: Start indoors 4-6 weeks before the last frost.
• Outdoors: Direct sow in early spring as soon as the soil can be worked, or in late summer for fall bloom.

Prepare Your Materials

• Seed-starting trays or pots (if indoors)
• Well-draining potting mix
• Humidity dome or plastic wrap to hold moisture
• Spray bottle for misting

Sowing the Seeds

• Sow seeds 1/4 inch deep and cover with soil, as the seeds need darkness to germinate.
• No special seed treatment is needed; the large, curved seeds are easy to handle.

Provide the Right Conditions

• Light: bright light for seedlings
• Temperature: soil temperature near 70°F (21°C) until germination

Germination

• Seeds sprout in about 6-14 days under warm, dark conditions.
• Move sprouted seedlings to a bright spot so they grow compact and sturdy.

Transplanting

• Set plants out once they have several true leaves and the soil can be worked.
• Thin or space plants 8-12 inches apart.

Care Tips

• Sun: full sun for the strongest stems and heaviest bloom.
• Water: give about 1 to 1-1/2 inches of water per week; avoid overwatering.
• Deadhead spent flowers regularly to encourage a longer bloom season.
• Pinch back young plants to encourage bushier growth.

Bloom Time:

Spring through early summer; blooming can pause in intense mid-summer heat and resume when nights cool.
