Place plants with similar water needs together so no water goes to waste.

One way to conserve water is to design a landscape plan that cuts down on the need for irrigation. According to the Environmental Protection Agency, converting to a water-efficient landscape can reduce your outdoor water use by 20% to 50%, or as much as 10,000 gallons a year. That saves money, too, shaving between $30 and $70 off the average annual household water bill.
