Lawn Calculators
Measure the area once. Seed, sod, soil, and fertilizer all start from that area. Lime starts from the rate on your soil test.
Mulch and gravel calculators are on the yard page.
Lawn Seed and Sod Calculators
Sod needs the roll size and the waste percent from you. Neither is preset.
Soil and Fertilizer Calculators
Topdressing starts at the cited 1/4 inch compost depth. Topsoil depth is yours. Fertilizer uses the percent on the bag. Lime uses the soil-test rate.
Grass Seed Rates by Type
Six grasses. St. Augustinegrass has no seed rate. Warm-season mowing and germination are not verified.
