Maintaining a lush lawn doesn’t have to mean excessive water use. Letting your grass grow longer—about three to four and a half inches—can shade the soil and reduce evaporation. Longer grass also develops deeper roots, allowing it to access moisture deeper in the soil. Additionally, using mulch mode on your mower helps retain soil moisture and returns nutrients to the ground. For a more sustainable option, consider replacing grass with drought-tolerant plants, mulch, or ornamental grasses.
