Firm in the seed. Even if it were practical on a large planting, seed that is buried too deep will never germinate. Instead, walk across the seedbed, tamping it down with your foot or the head of a garden rake, to ensure good contact between the seeds and the ground. An even better method is to rent a lawn roller, a large cylinder that you fill with water and then push over the seedbed to firm it down. Water and, if needed, fertilize.
Seeds require water to germinate.
You should water during dry periods until the plants are about 1 to 2 inches tall. After that point, water only if plants look wilted or stressed. Wildflowers normally grow well in average soil and don t require fertilizer. If your wildflowers germinate well and grow thickly, they should choke out most weeds. When weeds do spring up in the midst of the wildflowers, pull them by hand before they have a chance to flower and disperse their seeds.
