Answer: Zinnia's are easy to grow from seed. Prepare your seedbed by removing any weeds, then cultivating the soil to loosen it. Sow the seeds on the surface of the soil and barely cover them with peat moss. Keep the seedbed moist but not soggy wet. Seeds will germinate in 5-24 days, depending upon temperature (70F-80F is ideal). Thin the seedlings from 6"-9" for dwarf species, 10"-12" for medium height species and 15"-18" for large species. Zinnia's grow best in full sun, with some afternood shade in very hot climates. When plants are young, pinch tips to stimulate bushy growth. Water regularly, keeping leaves dry, and deadhead frequently to keep plants looking neat.
Avoid overcrowding your plants and you'll avoid powdery mildew disease. Enjoy your zinnias!
