Mow regular and at the correct height. An good final finish to planting a Centipede grass lawn is to roll your planted lawn area with a hand roller. You can rent these implements from rental stores in your area. This compacts the soil around the seed, creating a more favorable environment for Bahiagrass seed germination. The rolling also smoothes the soil providing for a more level lawn and a later beautiful turf.
