Save by Knowing How to Water the Lawn
Posted by Brenna Malmberg
Growing up, I remember sitting on the front porch steps watching water cascade out the sprinkler. I also remember running through that same water that was nourishing our green grass. I can't say Dad was always thrilled with that last part, but for a kid, staring at a sprinkler is only so fun. Back then, my dad knew all the tricks of watering the lawn, but in case you don't, I have some wisdom to share about how to water the lawn. And no, I don't think sprinting or leaping through the water will make the tip list. While fun, I don't think it helps save money or the environment.

The EPA estimates that 50 percent of outdoor water is wasted because of inefficient watering methods. With these eight tips on how to water the lawn, you can save water and have a healthier lawn.
- Morning showers. The best time to water your lawn is in the morning. Ideally, water between 4 and 10 a.m. Mornings offer cooler temperatures and low winds. This keeps water from evaporating before it soaks in. Any excess water will evaporate as the day continues, decreasing the chance of a grass fungus. Watering in the afternoon increases evaporation, which inefficiently uses water. If you water in the evenings, the water can sit and cause a fungus to grow.
- Long and strong. Set your mower blade to a higher setting. The longer the grass, the longer and healthier the root system is below the ground.
- An inch a week. Generally, an inch a week will keep your grass healthy. To check to see how much water your sprinkler dumps, place a container in the water’s path. Note how much time it takes the water to reach an inch. If you water too much, fungi and shallow root systems develop. Also remember to look at the weather forecast. If you receive the inch you need from rain, you won’t need to water the rest of the week.
- Grass check. Press your foot into the grass. If it springs back, it’s healthy and full of water. You won’t need to water it yet.
- Sprinkler choice. While an in-ground irrigation system works best (especially a WaterSense approved irrigation system), a pulsating sprinkler is the next best thing. This type shoots out water horizontally at a high velocity, decreasing evaporation before it reaches the grass. Also, make sure your sprinkler is spraying only on the grass, not on sidewalks, driveways or walls. Those places don’t need watering.
- Leak fixer. Check for leaks in the hose, sprinkler head or water spigot. If it’s leaking, that water is being wasted on the ground.
- Automatic clock. Use a timer to turn off the water. It’s easy to get distracted while you are watching TV or getting ready for work, so invest in a timer. They generally cost $10 at home stores. They connect right to the spigot.
- Native species. Reduce your grass’s dependence on water by planting a native species. They are more acclimated to the local climate and will require less water to survive. Stay away from grasses labeled “needs frequent attention” or anything else that makes it more difficult to keep alive. You might also see grasses labeled low water, such as Bermuda or Buffalo grasses, but you will need to check with your local nursery or extension office on what low water grasses grow in your area.
