To grow a new lawn from seed, calculate how much….

Seed you need for your area. Use a broadcast or drop spreader to apply seed. Cover seed with thin layer of topsoil or compost, about ¼” deep. Water. Keep moist. Don't allow topsoil or seeds to dry out. Water lightly, if needed, 3-4 times a day until grass is established. Allow grass to get about 3-4” high. Mow.
