Cover the seeds with a very thin layer of potting soil - about 1/4 inch deep. Moisten the soil before planting and water lightly afterward. When using potting soil I use 3 parts potting soil to 1 part water. Be sure to keep the soil moist. The seeds should germinate in 7 to 10 days. Fertilize when the plants get their second set of leaves. Best Nancy and Happy Yardening.
