Rake the soil, removing rocks and hard clods as you go.
Calibrate the spreader to deliver the seeds at the rate suggested on the grass seed package.
Fill the spreader with half the amount of grass seeds needed to seed your lawn. Spread the seeds, moving in straight lines in one direction.
Fill the spreader with the second half of the grass seeds and spread them in straight lines at a 90-degree angle to the first spreading.
Rake the soil to work the seeds into the top 1/4 inch of soil.
Fill the weighted roller no more than 1/2 full with water. Roll over the entire lawn to set the seed.
Cover the ground with a very light layer of straw mulch so that 25 percent of the soil shows through.
Water the seeds immediately after seeding using a sprinkler. Watch closely and use just as much water as the soil can hold. Stop if it begins to run off.
