In areas where winter is mild, you can direct sow in the fall, as well. Seeds germinate in 5-25 days. If starting indoors, maintain soil temperature at 12-21°C (55-70°F) and provide bright light.
Starting
Sow seeds on the surface of the soil. Transplant or thin to 15cm (6″).
Growing
Deadhead often and do not feed, as fertilizers can reduce flowering. Coreopsis will adapt to many different soils, but prefers well drained, rich soil. This annual species may self sow.
