How to grow Solanna Golden Sphere Coreopsis seeds

Choose Your Planting Method

• Indoors: Start 6-8 weeks before your last frost for first-year blooms.
• Outdoors: Direct sow in spring after the last frost, or in fall in mild climates.

Prepare Your Materials

• Seed-starting trays or pots
• Well-draining seed-starting mix
• Humidity dome or clear plastic wrap (optional)
• Spray bottle for misting

Sowing the Seeds

• Sow on the surface of the mix and press in firmly; do not cover the seeds, as they need light to germinate.
• Keep the surface of the mix moist but not waterlogged.

Provide the Right Conditions

• Light: Do not exclude light after sowing; bright light benefits germination and seedlings.
• Temperature: 65-77°F (18-25°C).

Germination

• Seeds germinate in 1-3 weeks.
• Transplant seedlings to small pots when large enough to handle.

Transplanting

• Acclimate young plants to outdoor conditions for a week or two before planting out after all risk of frost.
• Space plants 9-12 inches (23-30 cm) apart.

Care Tips

• Sun: Full sun for the heaviest bloom.
• Water: Water until established; mature plants prefer average to dry soil and dislike constant wetness.
• Fertilizer: Not heavy feeders; rich, over-fertilized soil causes floppy growth.
• Deadhead regularly to prolong flowering; cut plants back by half if bloom slows midseason.

Bloom Time:

June through September.
