Keep Your Lawn Water Smart This Summer

Junuary is finally over!

That means the rains have finally stopped and we’re in for a dry, hot summer. As the warm weather settles in, it’s time to think about the whens and hows of outdoor watering.

Not watering your lawn? No problem.

Don’t forget that a well-maintained lawn can be left unwatered during the summer months without damaging the grass. The lawn won’t die, it’ll just go dormant (think of it as taking a long summer nap). Your green lawn will return quickly when the rainy season returns.

If you do plan to irrigate this summer, first measure your sprinkler’s output, then make it easy on yourself and let the experts tell you when to water.

Weekly Watering Number toolWhat’s your number?

The Weekly Watering Number is a service provided by our friends at the Regional Water Providers Consortium. The Weekly Watering Number tells you the amount of water (in inches) your lawn will need each week. It’s available every Thursday from April through September.

Mow More, Water Less

You can also save water by mowing frequently (about once a week). Mowing a little each time can encourage robust root development. And stronger roots mean less water and maintenance is needed.

While the ideal mowing height depends on what kind of grass you have, a good rule of thumb is to always maintain 2/3 of the original height of the lawn.
