Planting & Care

Sow Rosella Dahlia seeds indoors in a sterile seed-starting mix, pressing them lightly into the surface as they need light to germinate. Keep the soil consistently moist but not waterlogged, and maintain a temperature around 70°F. Once seedlings have developed true leaves and all danger of frost has passed, harden them off and transplant to a sunny garden location with well-drained soil. Space plants 12-18 inches apart to allow for good air circulation.

Water regularly during the growing season, especially during dry spells, but avoid overhead watering to prevent disease. Mulch around plants to conserve moisture and suppress weeds. Fertilize monthly with a balanced fertilizer. In cooler zones, dig up tubers in fall and store them indoors over winter; in warmer zones, plants can be left in the ground with a layer of mulch for protection.
