3. Add topsoil
After clearing the yard, add about ¼ inch thick of enriched topsoil using a fertilizer spreader. This mixture of soil and nutrient-rich compost will help your new turf to grow quicker, thicker, and healthier.

Use grass seeds similar to your existing turf or a compatible type of grass to overseed your lawn. Put the grass seeds in a fertilizer spreader and walk across your property in rows as you spread the mixture.
5. Fertilize
