a piece of land covered with grass that is kept mowed and trimmed evenly. There are parterre, park, sport, and moresque (motley colored) lawns.
Lawns are a basic element of flower gardens and parterres and serve as a background for flower beds and decorative trees as well as for sculptures and fountains. Park and moresque lawns are arranged in parks, gardens, public gardens, and boulevards. Grass seed is sown primarily in the spring by hand or by seeding machines that are driven in perpendicular directions. Then the lawn is raked manually or mechanically and rolled. The combination of grasses for lawns is chosen to create thick herbage and a dense turf. The cereals, such as meadow grass, fescue, ryegrass, and bent, are sown 15-30 g of seeds per sq m. Moresque lawns combine a mixture of cereals and annuals with beautiful blossoms, such as the poppy, cornflower, calendula, and candytuft. Lawn care includes watering, fertilizing, mowing, weeding, and additional sowing.
