Description
Full sun is essential with a minimum daylight temperature of 60 degrees F. Zinnias are adaptable but prefer fertile, humus-rich, well drained soil at pH preference 5.5 – 7.5. If soil is amended with compost, the flowers will grow more quickly. Sow seeds 1/4-inch deep. Space plants 6-10 inches apart. Germination occurs at 74 to 80 degrees F in 5 to 10 days. Sow in succession for a longer flowering display.
