Healthy lawns don't need that much water. Watering too often keeps the grass from establishing deep roots. When you water, deep soak your lawn, allowing the moisture to reach the roots. Healthy roots are more water efficient and drought tolerant.
Mow your lawn at a minimum 3 inch height. This is the most important step to a healthy lawn. Keeping your grass a bit longer will allow it to develop a larger root system and will also shade out weed seedlings. Keep your mower blades sharpened to reduce damage.
Water before 8 a.m. or after 8 p.m. After 8 a.m. heat steals moisture from your lawn through evaporation. Watering during the day can actually scald or burn your lawn when hot sunlight hits the water droplets. Watering early equals less water used.
Leave grass clippings on the grass. Leaving clippings on the lawn has been proven to help your lawn. Nitrogen from the clippings is returned to the soil, nourishing your lawn.
Reduce the size of your lawn. Include shrubs, trees, and wildflowers in your landscape. They don't require as much water or upkeep. Planting more trees provides more shade, keeping your lawn greener!
