A lawn is an area of soil-covered land planted with grasses or (rarely) other durable plants such as clover which are maintained at a short height with a lawnmower and used for aesthetic and recreational purposes. Common characteristics of a lawn are that it is composed only of grass species, it is subject to weed and pest control, it is subject to practices aimed at maintaining its green color (e.g., watering), and it is regularly mowed to ensure an acceptable length, although these characteristics are not binding as a definition. Lawns are used around houses, apartments, commercial buildings and offices. Many city parks also have large lawn areas. In recreational contexts, the specialised names turf, pitch, field or green may be used, depending on the sport and the continent.
The term “lawn”, referring to a managed grass space, dates to no earlier than the 16th century. Tied to suburbanexpansion and the creation of the household aesthetic, the lawn is an important aspect of the interaction between the natural environment and the constructed urban and suburban space. In many suburban areas, there are bylaws in place requiring houses to have lawns and requiring the proper maintenance of these lawns. In some jurisdictions where there are water shortages, local government authorities are encouraging alternatives to lawns to reduce water use.
Prior to European colonization, the grasses on the East Coast of North America were mostly broom straw, wild rye, andmarsh grass. As Europeans moved into the region, it was noted by colonists in New England, more than others, that the grasses of the New World were inferior to those of England and that their livestock seemed to receive less nutrition from it. In fact, once livestock brought overseas from Europe spread throughout the colonies, much of the native grasses of New England disappeared, and an inventory list from the 17th century noted supplies of clover and grass seed from England. New colonists were even urged by their country and companies to bring grass seed with them to North America. By the late 17th century, a new market in imported grass seed had begun in New England.
Much of the new grasses brought by Europeans spread quickly and effectively, often ahead of the colonists. One such species, Bermuda grass (Cynodon dactylon), became the most important pasture grass for the southern colonies.
Kentucky Bluegrass (Poa pratensis) is a grass native to Europe or the Middle East. It was likely carried to Midwestern United States in the early 1600s by French missionaries and spread via the waterways to the region around Kentucky. However, it may also have spread across the Appalachian mountains after an introduction on the east coast. Kentucky Bluegrass is now one of the top three pasture grasses in the United States and the most desirable species of grass for lawns.
Farmers at first continued to harvest meadows and marshes composed of indigenous grasses until they became overgrazed. These areas quickly fell to erosion and were overrun with less favorable plant life. Soon, farmers began to purposefully plant new species of grass in these areas, hoping to improve the quality and quantity of hay to provide for their livestock as native species had a lower nutritive value. While Middle Eastern and Europeans species of grass did extremely well on the East Coast of North America, it was a number of grasses from the Mediterranean that dominated the Western seaboard. As cultivated grasses became valued for their nutritional benefits to livestock, farmers relied less and less on natural meadows in the more colonized areas of the country. Eventually even the grasses of the Great Plains were overrun with European species that were more durable to the grazing patterns of imported livestock. A pivotal factor in the spread of the lawn in America was the passage of legislation in 1938 of the 40-hour work week. Until then, Americans had typically worked half days on Saturdays, leaving little time to focus on their lawns. With this legislation and the housing boom following the Second World War, managed grass spaces became more commonplace. The creation in the early 20th century of country clubs and golf courses completed the rise of lawn culture.
American lawn culture
Lawn monoculture was a reflection of more than an interest in offsetting depreciation, it propagated the homogeneity of the suburb itself. Although lawns had been a recognizable feature in English residences since the 19th century, a revolution in industrialization and monoculture of the lawn since the Second World War fundamentally changed the ecology of the lawn. Intensive suburbanization both concentrated and expanded the spread of lawn maintenance which meant increased inputs in not only petrochemicals, fertilizers, and pesticides, but also natural resources like water.
Front lawns became standardized in the 1930s when, over time, specific aspects such as grass type and maintenance methods became popular. The lawn-care industry boomed, but the Great Depression of the 1930s and in the period prior to World War II made it difficult to maintain the cultural standards that had become heavily associated with the lawn due to grass seed shortages in Europe, America’s main supplier. Still, seed distributors such as Scotts Miracle-Gro Company in the United States encouraged families to continue to maintain their lawns, promoting it as a stress-relieving hobby. During the war itself, homeowners were asked to maintain the appearances of the home front, likely as a show of strength, morale, and solidarity. After World War II, the lawn aesthetic once again became a standard feature of North America, bouncing back from its minor decline in the decades before with a vengeance, particularly as a result of the housing and population boom post-war.
The G.I. Bill in the United States let American ex-servicemen buy homes without providing a down payment, while the Federal Housing Administration offered lender inducements that aided the reduction of down payments for the average American from 30% to as little as 10%. These developments made owning your own home cheaper than renting, further enabling the spread of suburbia and its lawns.
Levittown, New York was the beginning of the industrial suburb in the 20th Century, and by proxy the industrial lawn. Between 1947 and 1951, Abraham Levitt and his sons built more than seventeen thousand homes, each with its own lawn. Abraham Levitt wrote “No single feature of a suburban residential community contributes as much to the charm and beauty of the individual home and the locality as well-kept lawns”. Landscaping was one of the most important factors in Levittown’s success – and no feature was more prominent than the lawn. The Levitts understood that landscaping could add to the appeal of their developments and claimed that, “increase in values are most often found in neighborhoods where lawns show as green carpets” and that, over the years, “lawns trees and shrubs become more valuable both esthetically and monetarily”. During 1948, the first spring that Levittown had enjoyed, Levitt and Sons fertilized and reseeded all of the lawns free of charge.
The economic recession that began in 2008 has resulted in many communities worldwide to dig up their lawns and plant fruit and vegetable gardens. This has the potential to greatly change cultural values attached to the lawn, as they are increasingly viewed as environmentally and economically unviable in the modern context.
Ground cover alternatives
Some lawns are replaced with low ground covers, such as creeping thyme, camomile, Lippia, purple flowering Mazus,grey Dymondia, creeping sedums, and creeping jenny. Other alternatives to lawns include meadows, drought-tolerantxeriscape gardens, natural landscapes, native plant habitat gardens, paved Spanish courtyard and patio gardens,butterfly gardens, rain gardens, tapestry lawn and kitchen gardens. Trees and shrubs in close proximity to lawns provide habitat for birds in traditional, cottage and wildlife gardens.
Lawn care and maintenance
Seasonal lawn establishment and care varies depending on the climate zone and type of lawn grown.
Planting and seeding
Early autumn, spring, and early summer are the primary seasons to seed, lay sod (turf), plant ‘liners’, or ‘sprig’ new lawns, when the soil is warmer and air cooler. Seeding is the least expensive, but may take longer for the lawn to be established. Aerating just before planting/seeding may promote deeper root growth and thicker turf.
Sodding (American English), or turfing (British English), provides an almost instant lawn, and can be undertaken in most temperate climates in any season, but is more expensive and more vulnerable to drought until established.Hydroseeding is a quick, less expensive method of planting large, sloped or hillside landscapes. Some grasses and sedges are available and planted from ‘liner’ and 4-inch (100 mm) containers, from ‘flats’, ‘plugs’ or ‘sprigs’, and are planted apart to grow together.

Fertilizers and chemicals
Various organic and inorganic or synthetic fertilizers are available, with instant or time-release applications. Pesticides, which includes biological and chemical herbicides, insecticides and fungicides are available. Consideration for their effects on the lawn and garden ecosystem and via runoff and dispersion on the surrounding environment, can constrain their use. For example, the Canadian province of Quebec and over 130 municipalities prohibit the use of synthetic lawn pesticides. In order for the lawn to grow and flourish, the soil must be prepared properly. If this step is overlooked as many do, the lawn will burn out as soon as it runs out of nutrients.  The Ontario provincial government promised on 24–2 September 2007 to also implement a province-wide ban on the cosmetic use of lawn pesticides, for protecting the public. Medical and environmental groups support such a ban. On 22–2 April 2008, the Provincial Government of Ontario announced that it will pass legislation that will prohibit, province-wide, the cosmetic use and sale of lawn and garden pesticides. The Ontario legislation would also echo Massachusetts law requiring pesticide manufacturers to reduce the toxins they use in production.
Sustainable gardening uses organic horticulture methods, such as organic fertilizers, biological pest control, beneficial insects, and companion planting, among other methods, to sustain an attractive lawn in a safe garden. An example of an organic herbicide is corn gluten meal, which releases an ‘organic dipeptide’ into the soil to inhibit root formation of germinating weed seeds. An example of an organic alternative to insecticide use is applying beneficial nematodes to combat soil-dwelling grubs, such as the larvae of chafer beetles. The Integrated Pest Management approach is a coordinated low impact approach.
Mowing and other maintenance practices
Maintaining a rough lawn requires only occasional cutting with a suitable machine, or grazing by animals. Maintaining a smooth and closely cut lawn, be it for aesthetic or practical reasons or because social pressure from neighbors and local municipal ordinances requires it, necessitates more organized and regular treatments. Usually once a week is adequate for maintaining a lawn in most climates. However, in the hot and rainy seasons of regions contained inhardiness zones greater than 8, lawns may need to be maintained up to two times a week.
Corry is a city in northwestern Pennsylvania in the United States. With a population of 6,605 at the 2010 United States Census, it is the second largest city in Erie County. Corry is a part of the Erie, PA Metropolitan Statistical Area. The city became famous in the late-19th and early-20th centuries for being the manufacturer of Climax locomotives.
Erie County was formed from parts of Allegheny County on March 12, 1800. On May 27, 1861, tracks owned by the Atlantic and Great Western Railroad intersected with those of the Sunbury and Erie Railroad and was called the “Atlantic and Erie Junction”. Land at the junction was owned by Hiram Cory, who sold a portion to the Atlantic and Great Western in October 1861. The railroad built a ticket office at the junction and named it for Cory, but through a misspelling it became Corry.
The combination of railroad growth and the discovery of oil in nearby Titusville contributed greatly to Corry’s development. This boomtown was chartered as a borough in 1863 and designated as a city in 1866. Industry has played a big part in Corry’s growth, and the Corry Area Historical Society maintains a museum where one of the Climax locomotives (the steam engine used in logging operations that brought fame to Corry) is on display.
