Water Less
If you water your lawn every day, you are encouraging shallow roots. Generally, watering deeper on fewer days per week will encourage deeper root growth and a healthier lawn. Water your lawn only when the grass does not spring back when you step on it. Set a kitchen timer to remind yourself to turn your sprinkler off.
Shady Areas
Water areas that are in the shade about 30% less than sunny areas. Shade creates a microclimate of cooler temperatures and lower evaporation, so plants need less water.
