I have a large sunny area, it has been worked over with a bobcat and graded /smoothed pretty well. I raked up as many rocks and roots as I could. I spread Bermuda seed (Vigoro brand) and starter fertilizer. Since I put it down the ground is hard as a rock from no rain. It's too far from my house to water with a sprinkler. Do you think it will come up or will it just wash with the first good rain ? Any other ideas to save my seed ?
