Prepare the soil. Aerating will likely improve the quality of the soil and allow grass to grow. Supply adequate drainage opportunities if your grass drains poorly. For instance, installing drainage pipes or subsoil can greatly improve the draining capabilities of the soil. The seeds won't grow if there is too must moisture in the soil.
Pour seed into a seed spreader and set the dial according to the specifications on the package. In general, 4 lbs. of grass should be used for 1,000 square feet of lawn, but , the measurement may vary by grass type. Walk back and forth over your lawn in even lines to spread the seed. Walk at a steady pace to ensure the same amount of seed is distributed throughout your lawn.
Cover your seed, if necessary. Large seeds, such as rye and chewnings fescue, must be covered with soil in order to germinate. Smaller seeds typically do well when on top of the soil or slightly dusted with soil, depending on the variety. A light covering of straw or cheesecloth keeps the seeds close to the ground and prevents them from being washed away during the rain if on a slope. Keep the covering on the seeds until the grass starts to sprout.
Water a newly seeded lawn whenever the soil begins to dry out. Use a hose or a sprinkler system to moisten the soil. Avoid saturating the soil, which can wash away the seeds and prevent proper growth of those that remain.
