Answer» Irrigation: Lawn grasses are shallow-rooted; therefore, require frequent light irrigation. Use of sprinkler irrigation can save water and number of man-days (labour) to a considerable extent. In summers watering is done at two days interval while in winters irrigation frequency is reduced to once a week. Mowing: Lawn grass should be allowed to grow 5-6 cm during any season. In a single mowing, only 33-40% of the clippings should be removed. Fertilization: Broadcasting a fertilizer (NPK) mixture at the rate of 50-60 g/m2 during Feb-March and August- September is necessary for a lush green lawn. Spraying of Urea at 0.3% is also beneficial Dethatching: The process of removing a layer of dead and decaying organic debris and the living roots, crown, and stems of the lawn grass (thatch) from the top layer is known as dethatching. Liming: Growth of moss over the lawn area is an indication of acidic soil, which means the soil requires liming. Under such condition, powdered chalk or lime should be applied at the rate of 250 gm per m2 area. |
