Planting & Care

Sow Cool Flame Dahlia seeds indoors 6-8 weeks before the last frost date. Press seeds lightly into the soil surface and keep moist but not waterlogged at around 70°F (21°C). Germination typically occurs in 7-14 days. Once seedlings have developed true leaves and all danger of frost has passed, harden them off and transplant outdoors in a sunny location with well-drained soil. Space plants 12-18 inches apart to allow good air circulation.

Water regularly to keep the soil evenly moist, but avoid overwatering. Mulch around plants to retain moisture and suppress weeds. Fertilize monthly with a balanced fertilizer to encourage healthy growth and abundant blooms. Deadhead spent flowers to prolong the blooming season. In colder zones, dig up tubers in fall and store them indoors over winter, or treat plants as annuals.
