Your Lawn You can save money and still maintain a nice lawn. On average, an inch of water every four days is enough. Follow the directions below suggested by the South Jersey Resource Conservation and Development Council. When and How Much to Water Lawns should be watered about every four days. Soil texture determines the actual frequency.
Sandy soil needs to be watered more often.
Place three or more coffee-type cans at various locations on your lawn. Use the Homeowner Lawn Watering Guide below to determine the amount of time to water. The amount of rainfall during a four-day interval will change the amount of water needed. Abnormal cloudiness or hot winds will also cause variations from the average. The best way to cut down on your water bill is to cut down on your outdoor water use.
