Planting Instructions for California Giant Mix Zinnia Seeds

Start Zinnia seeds indoors 4 weeks before transplanting outdoors. In a 4 1/2″ pot, sow seeds 1/4″ deep and cover lightly. Germinate seeds at 70°F for 7 – 14 days. After the first true leaf appears, lower temperature to 60°F until transplanted outdoors. Space plants 6-12″ apart in full sun. Seeds may also be sown outdoors after soil has warmed up to 65 – 70°F. Zinnias are heat tolerant and make great cut flowers.
