Planting & Care

Sow American Sun Dahlia seeds indoors 6-8 weeks before the last frost date. Use a well-draining seed-starting mix and lightly cover the seeds with about 1/8 inch of soil. Keep the medium consistently moist but not waterlogged, and maintain a temperature of 65-75°F. Provide bright light once seedlings emerge to encourage strong growth. Harden off seedlings gradually before transplanting outdoors after the danger of frost has passed.

Plant dahlias in a sunny location with well-drained soil. Space plants 12-18 inches apart to allow good air circulation. Water regularly, especially during dry periods, but avoid overwatering. Pinch back the growing tips when plants are about 6 inches tall to promote bushier growth and more blooms. Deadhead spent flowers to encourage continuous flowering. In colder zones, dig up tubers in fall and store them indoors for winter, or treat as annuals and replant each year.
