California Giants - Zinnia Seeds

Plant seeds directly in the garden after average last frost date when soil has warmed up. Optimum soil temperature for seed germination is 70-90°F. Or, start seed indoors 3-4 weeks before transplanting into the garden. Transplant to the garden 2 to 3 weeks after your average last frost. A week before transplanting time, harden off plants by exposing them to an increasing number of hours outdoors each day. Requires full sun and well drained soil. Cut back old blossoms to encourage new growth.
