Lawn care is the set of practices used to keep a lawn healthy and attractive. A lawn is an area of grass that forms a uniform, perennial ground cover; lawn grasses tolerate regular mowing and foot traffic because their growing point, the crown, sits near the soil surface.[1] The main practices are mowing, fertilizing, watering, aeration, overseeding, and the control of weeds, pests and diseases.[2]
The right grass and practices depend largely on climate. Warm-season grasses such as bermudagrass and zoysiagrass grow best at 80–95 °F, while cool-season grasses such as Kentucky bluegrass and tall fescue grow best at 60–75 °F.[3] Most lawns in Georgia are warm-season grasses,[4] while most lawns in Illinois are cool-season grasses.[5]
History
Until the 19th century, the lawns of large estates were kept short by grazing animals or cut by hand with scythes; scything a single acre took three men a full day.[9] In Britain lawns were costly to keep because of that labor, so they were mainly a feature of wealthy estates.[10] In 1830 Edwin Budding of Stroud, Gloucestershire, patented the first lawn mower, adapting a machine used to shear cloth.[7][9] He built it with the manufacturer John Ferrabee, and production was later licensed to Ransomes of Ipswich; more than 1,000 mowers had been sold by 1840.[9]
In the United States, lawns spread slowly until the late 19th century, when suburban setback rules led builders to plant grass around new houses.[10] After World War II, developments such as Levittown, New York, were built with a grass-centered landscape, and the mass-produced rotary mower made lawn care practical for ordinary homeowners. Crabgrass, other weeds and summer heat stress in turn drove demand for herbicides, insecticides and fertilizers.[10]
Grass selection
Lawn grasses fall into two groups. Warm-season grasses, including bermudagrass, zoysiagrass, centipedegrass and St. Augustinegrass, grow best at 80–95 °F; cool-season grasses, including Kentucky bluegrass, tall fescue, perennial ryegrass and fine fescues, grow best at 60–75 °F.[3] In the transition zone between the two climates, winters are often too cold for warm-season grasses and summers too hot for cool-season grasses to grow well.[11]
Most Georgia lawns are warm-season grasses, and the University of Georgia advises against mixing warm- and cool-season grasses in one lawn; tall fescue is best adapted to the state's Piedmont and mountain regions.[4] In Illinois, most lawns are cool-season grasses, with Kentucky bluegrass the most popular choice.[5]
Mowing
The basic rule of mowing is to remove no more than one-third of the leaf tissue at a time, mowing when the grass needs it rather than on a fixed schedule.[2] Grass clippings are more than 90% water and do not cause thatch; leaving them on the lawn returns roughly one pound of nitrogen per 1,000 square feet a year, about one normal fertilizer application.[2]
Fertilizing
Fertilizer timing should follow a grass's active growth: generally spring and fall for cool-season lawns, and early and late summer for warm-season lawns.[12] A soil test reports pH and nutrient levels such as phosphorus and potassium, and the University of Georgia recommends using one to guide lawn fertilization.[13]
Watering
Established lawns generally need about one inch of water a week from rain or irrigation, ideally applied in the early morning.[2][14] In the United States, residential outdoor water use is nearly 8 billion gallons a day, mostly for landscape irrigation,[15] and the EPA estimates that up to half of outdoor water is wasted through overwatering by inefficient irrigation.[16]
Under Georgia's Water Stewardship Act, in effect statewide since June 2, 2010, outdoor landscape watering on permitted water systems is limited to the hours between 4 p.m. and 10 a.m.; newly installed turf is exempt during installation and for 30 days afterward.[17]
Aeration and overseeding
Core aeration removes small plugs of soil to relieve compaction and thatch, and is typically done in fall or spring; bare areas of cool-season lawns are best overseeded in fall.[2] In Illinois, fall is also the season to fertilize, core aerate, overseed and treat perennial broadleaf weeds.[18]
Weeds, pests and diseases
Almost all lawn diseases are caused by fungi, and a disease develops only when a pathogen, a susceptible grass and a favorable environment are present at the same time.[19] In the United States, pesticides used on lawns are regulated by the Environmental Protection Agency under the Federal Insecticide, Fungicide, and Rodenticide Act, which requires most pesticides to be registered before they can be sold.[8] Most states also require a license to apply pesticides commercially.[20]
Environmental impact
A 2005 NASA-supported study estimated that U.S. lawns, including residential, commercial and golf turf, cover about 128,000 square kilometers, roughly three times the area of irrigated corn, which arguably makes turf the country's largest irrigated crop.[6] Most U.S. lawn grasses are not native to where they grow; the study's model found that without irrigation or fertilizer, lawn grass could grow in only a few areas of the Northeast and Great Plains, and that recycling clippings could nearly halve the synthetic nitrogen lawns need.[6]
To limit fertilizer runoff, the EPA advises against fertilizing before wind or rain or near waterways, filling spreaders on hard surfaces, and keeping clippings and leaves out of streams and storm drains.[12]
Industry
Historian Ted Steinberg cited 2005 estimates of 25–40 million acres of U.S. lawn, about 58 million home lawns and a lawn-care industry worth roughly $40 billion a year.[10] The U.S. Bureau of Labor Statistics counted about 1.3 million grounds maintenance jobs in 2025, with a median annual wage of $40,080, and projects employment to grow 5% from 2025 to 2035.[20]
