Grade the soil away from your house. Ensure that the yard drains toward a ditch or runoff area.
Till the soil and remove bark, sticks, rocks and other debris.
Test the soil with a home test kit or take a sample to your local extension office for analysis. Amend the soil as necessary to achieve a pH of 5 to 5.5. Centipede grass is very sensitive to pH. Add a 15-0-15 fertilizer to the soil; 2 lbs. per 1,000 square feet is sufficient. Do not over fertilize your centipede grass lawn.
Mix 20 lbs. of dry sand with 1 pound of centipede seed and spread in a criss-cross pattern. Using a cyclone-type seeder, lay the seed east to west, then south to north.
Spread straw or mulch over seed, especially on sloped areas to ensure the seed stays in place. The seed is slow to germinate, but should show in 2 to 3 weeks.
Water the seed so the top 1/2 inch of soil is always moist. Cut back on watering as seedlings start to grow.
