Push the blades of a motorized tiller about 6 inches into the soil. Push the tiller slowly up and down the area you intend to plant until the soil is loose and crumbly. Prepare the soil in the spring when temperatures reach 75 degrees F on a regular basis.
Broadcast, or toss, handfuls of grass seed over the tilled ground. The seed should look like it's being sprayed in an arc from your hand. Scatter a single layer over the ground, using no more than 3 lbs. of seed per 1000 square feet of land.
Broadcast handfuls of rich potting soil over the freshly sown seed. The nutrients in potting soil will help the grass sprout more quickly. Bermuda grass requires about ¼ inch of soil above it to germinate.
Rake the potting soil out smooth with a garden rake. Don't worry if some of the seeds come up to the top of the soil; many more will germinate under the soil. Bermuda grass reproduces and spreads in just a few weeks.
Water the entire area, using about 5 gallons of water per 100 square feet. This should be enough to moisten the soil without making it soggy or muddy.
Push a hand roller over the entire area to push the seeds further into the soil, encouraging germination. Grass should sprout within a month.
