Field notes
The calculator set covers fertilizer, seed, sod, and lime, with inputs tailored to each task: fertilizer-bag numbers and lawn area, a soil-test recommendation, or a user-set sod waste allowance. The frost-date section identifies NOAA 1991–2020 normals and offers 10, 50, and 90 percent freeze levels; the site says a ZIP lookup finds the nearest weather station. Its guides compare grass types and cite extension-service rates.
