The sight of a bald spot can ruin a perfect, green lawn. Luckily, it's easy to cover up and fix bald spots on a lawn. Before fixing the lawn it's best to determine what caused the bald spot and address that issue. Refer to the "Tips" section of this article for information on common lawn problems and their appropriate remedies. There are two primary methods to repair bald spots in a lawn: resodding and reseeding. Resodding is best for small patches of bald spots. Reseeding is recommend for large bald spots, or if it's necessary to replace the entire lawn.
Cut the size and shape of new sod by laying a piece of sod over the bald spot. Cut through the damaged spot and new sod at the same time.
Remove the damaged grass if it's not completely bald.
Lay down a layer of topsoil and place the sod cutout on top of it.
Water the new sod daily for a few weeks until it blends in with the rest of the lawn.
Mow the bald spot and surrounding grass, and then use a metal rake to remove all of the dead grass from the bald spot.
Prepare the soil for the new seed by using the rake to loosen up the soil. This will allow the roots to grow more easily. If the soil is hard, such as clay soil, remove a portion of the original soil and replace with topsoil.
Spread the new seeds using a hand spreader or broadcast spreader. It's best not to just sprinkle seeds by hand, as they won't spread evenly. Cover the seed by lightly raking the area, and then lightly tamp the area down with a flat object, such as the back of a flat shovel or with a hoe.
Water seeds three times daily for about one to two weeks, and then only water once daily. Do not mow the grass until it has reached 3 inches tall.
