ZinniaZinnias are very easy to grow, they come in a wide range of colors, and they have long stems making them perfect for flower arrangements. Zinnias thrive in full sun and can tolerate quite a bit of heat, which makes them the perfect summer flower.
Sowing Information
Direct seed: Zinnia seeds can be planted directly into the garden when the soil has warmed to 70 degrees and all danger of frost has passed. Sow the seeds 1/4" deep and keep moist until germination. Thin plants to about 10" apart. Transplants: To get a jump on the season it is best to start zinnias indoors about 6 weeks before the last average frost date for your area. Sow seeds in seedling flats and cover lightly with soil. Keep moist until germination, which should occur within 5 days at 80 degrees. A heat mat will aid in the process of germination. Plant seedlings outside in early summer after all danger of frost has passed. Light Preference
