Zinnia (A)
Zinnia angustifolia, Zinnia elegans
Annual
Zinnias are usually direct seeded after last frost. Or start inside 6 weeks before last frost. Lightly cover and provide warmth, 21-27°C (70-80°F). Germinates in 5-10 days. Transplant after last frost into a full sun location, 6-12 inches apart. Pinch out the growing tip to encourage branching. Provide good air circulation, water, fertilize, and deadhead regularly. Zinnias are susceptible to mildew.
