Lawn
A lawn is an area of recreational or amenity land planted with grass, and sometimes clover and other plants, which are maintained at a low, even height.
The specialised names turf, pitch, field or green may be used, depending on the sport and the locale.
Usage
Lawns are a standard feature of ornamental private and public gardens and landscapes in much of the world today. Lawns are created for aesthetic use in gardens, and for recreational use, including sports. They are typically planted near homes, often as part of gardens, and are also used in other ornamental landscapes and gardens.
Lawns are frequently a feature of public parks and other spaces. They form the playing surface for many outdoor sports, reducing erosion and dust as well as providing a cushion for players in sports such as Rugby, football, cricket, baseball, golf, tennis, bocce and stake.
Many different species of grass are used, often depending on the intended use of the lawn, with vigorous, coarse grasses used where active sports are played, and much finer, softer grasses on ornamental lawns, and partly on climate, with different grasses adapted to oceanic climates with cool summers, and tropical and continental climates with hot summers.
It is also not uncommon to mix grass seeds. A 50/50 mixture of grass types can, for example, form a stronger lawn when one grass type does better in the warmer seasons and the other is more resistant to colder weather.
History
Before the invention of mowing machines in 1830, lawns were managed very differently. Lawns belonging to wealthy people were sometimes maintained by the labour-intensive methods of scything and shearing—in most cases, however, they were pasture land which was maintained through grazing by sheep or other livestock. Areas of grass grazed regularly by rabbits, horses or sheep over a long period often form a very low, tight sward similar to a modern lawn.
