With an estimated 50 million lawns in America, covering about 30 million acres of land, the environmental impact of overwatering, chemical fertilization, and pesticides is huge. Now you can enjoy the lushest patch of grass you've ever had, the sustainable way. No matter how much space you have to work with, here's how to make it your own.

Use water wisely.
The most efficient way to keep a lawn from getting thirsty without wasting water is with an underground irrigation system. "A well-maintained system can reduce water use by 9,000 gallons annually," says Virginia Lee, of the EPA's Water Sense. "That's the equivalent of a garden hose running all day nonstop." You can search by state for an EPA-endorsed company that will install an irrigation system using a smart controller at the Watersense website. If you must water yourself, do it in the morning, and only until grass is wet to the touch. Up to 50 percent of water is lost by evaporation or oversaturation.
