Carpetgrass, also known as flatgrass, is found all over the United States in pastures and lawns. Native to the Gulf Coast and warmer climates, this perennial grass is round tipped and tall, with a tall seedstalk at the top. Carpetgrass requires a loose seed bed for proper growth and can be grown from seed or sprigs. Seeding during mid-April to May is ideal for the best results in most climates. Seeding after September usually will not produce a thick lawn.
Run a tiller over the area of lawn you wish to plant the seed to break up the topsoil. This will help the seed take root. Alternatively, if you are planting a small section, use a grass drill to establish holes for the seed.
Spread the carpet seed over the lawn using a grass seed spreader and a rake. Apply 2 pounds of grass seed per 1,000 square feet of yard.
Rake the lawn after seeding to help cover the seed with soil.
Water the soil so that it is wet to about 1 inch. Keep the soil moist but not soaking wet for the next two weeks.
Water the lawn lightly until rooting of the grass begins and it begins to spread. After eight to 10 weeks the lawn will only need watered during drought conditions.
Apply fertilizer to the lawn at 1 pound of nitrogen per 1,000 square feet of lawn when the seed is planted and monthly until grass is covering the lawn.
