The Water-Wise Lawn Report 2026 was released on Mar. 16, providing homeowners with practical advice for reducing lawn water usage without harming their grass. The report outlines strategies such as deep watering, higher mowing, and smart irrigation timing to help lawns survive drought conditions while conserving water.
This topic is important as many regions face increasing droughts and water restrictions, making efficient lawn care essential for both environmental conservation and household budgets.
According to the report, most established lawns require only 1 to 1.5 inches of water per week, including rainfall. During periods of severe drought, the focus should shift from maintaining a lush appearance to simply keeping the grass alive by providing about one inch of water every two to three weeks. The guide recommends deep watering techniques that allow moisture to reach four to six inches into the soil and suggests using a tuna-can test to measure sprinkler output.
Mowing practices also play a significant role in moisture retention. Raising the mower deck during hot or dry periods helps shade the soil and encourages deeper root growth. The report advises following the one-third rule—never removing more than one-third of the grass blade at once—to avoid stressing the plant.
Irrigation timing is highlighted as another key factor. “The best watering window is early morning (4 a.m.–9 a.m.), to avoid midday evaporation and nighttime disease pressure,” according to the report. It also notes that using a WaterSense-certified smart controller can save an average home about 7,600 gallons of water per year by automatically adjusting watering schedules.
For those struggling with persistent lawn issues or high water bills, the report suggests seeking professional help through services like GreenPal, which connects homeowners with local lawn care providers familiar with efficient irrigation methods.
