Proper preparation and planning are key to planting a new lawn. Whether you are planting a lawn in a new house or replacing a lawn that had to be removed because of problems, the process of preparing the area and establishing the nutritional needs of the grass are basic steps to ensure healthy grass growth. The variety of grass you should plant will depend on how you will use your lawn and on your local growing conditions. For recommendations on varieties, contact your county agricultural extension.
Remove any construction debris, concrete and rocks if you are planting a lawn around a new home.
Loosen the topsoil down to between 8 and 12 inches by turning it with a shovel.
Break up the soil clumps with a hoe and rake.
Smooth the soil and create a slope that leads away from your house. The soil for your lawn should decline by 6 inches per 50 feet. This will help water run away from your house.
Take samples from the top 6 inches of soil in 10 or 15 parts of your yard. Mix these samples together and allow them to dry.
Send the soil to your agricultural extension for testing. The results will help you choose the correct fertilizer and amendments for your new lawn.
Install any desired in-ground sprinklers or irrigation according to the manufacturer's instruction. This step is optional.
Add any recommended soil amendments as instructed by the soil-testing facility.
Spread the seed with a spreader at the density indicated on the seed bag.
Go over the seeded lawn with a lawn roller. Lawn rollers press the grass seed into the soil to help it germinate and keep it from blowing away.
Mulch the seed to further protect it during germination, discourage weeds and help keep moisture in the soil.
Water as recommended on the bag of grass seed.
