Lime a lawn only when a soil test shows low pH, and spread it in fall or winter on dry, unfrozen turf so it has months to work. pH targets by grass, extension rates, NOAA freeze data for 22 cities, and where the West can skip it.
Feed a cool-season lawn its winterizer around the last mowing, weeks after the first frost and before your state’s cut-off. Warm-season lawns get no late-fall nitrogen.
Cool-season lawns get their main feeding in early fall; warm-season lawns are fed after green-up and stop six weeks before frost. Schedule, bag math and dates for 20 cities.
