Do you know all the ways to save money and conserve water in your lawn and garden? Try these: Water before 7 AM (saves 15-40 gallons of water per day). Use soaker hoses, drip irrigation, or a sprinkler that spreads large drops of water (mists waste water through evaporation). Water only 3 days a week (all that most gardens need), saving 35-50 gallons per day. Collect rainwater and gray water (from tub, sink, or wash) for use in gardening. Landscape your home with rocks, wood chips, or native plants, which use very little water.
