Prepare the planting area by adding any amendments, if applicable. Then, water the ground until it is damp to a 1-inch depth.
Fill a seed spreader with the desired type of grass seed. Use the amount specified on the seed bag for your size lawn. Push the spreader over the planting site in side-by-side rows until it is completely covered in grass seed.
Rake the soil lightly with a wide-toothed bow rake until the seed is approximately 1/4 inch deep. Some of the seed will still be visible on the surface.
Cut the twine on the peat moss bales using scissors, and then put on garden gloves.
Grasp large handfuls of the peat moss, and pull apart until it is loose and not clumped together. Spread it on top of the seeds in a 1/4- to 1/2-inch layer. Continue until the entire planting site is covered in peat moss.
Water the top of the peat moss with another 1/2 inch of water until it is moist and there are no dry spots.
