Protect young seedlings: mow only after they reach ~3 inches and hold off on weed pre-emergents until established.
Keep the seedbed consistently moist — roughly ¼ inch of water daily, split into shorter cycles if the surface dries out quickly. County-specific soil texture isn’t available here, so adjust to how fast your own soil drains.
You’re in the transition zone — both cool- and warm-season grasses can work; the schedule above follows the species you selected.
