A gorgeous and easy-to-grow multicolor cactus dahlia mix. Ideal for garden decoration and flowerpots.
Sow directly outdoors ¼-inch deep after the last frost when the soil temperature is 6570°F. Plant in well-drained soil in a sunny area. Cover seeds lightly but firmly. Keep surface moist until germination. Thin to 9-12 inches after the first true leaves appear. When started indoors, start 4 weeks earlier in a propagator sowing 3-4 seeds in each cell. Gently push them into good quality, moist compost, and cover them with ¼ sieved compost. Keep the soil moist. Once true leaves have grown, transplant them outside 14 inches apart into a sunny place.
