Why You Should Let Your Grass Go Gold

Keeping a green lawn is often a priority for homeowners in the United States. In fact, a well-maintained lawn is often viewed as a sign of success and a “physical manifestation of the American Dream of home ownership,” as Krystal D’Costa observes in Scientific American.

Keeping a green lawn throughout the warm season gives many homeowners a sense of pride, but what are the costs? Water overuse has drastic environmental impacts.

Water Overconsumption in the U.S.

Each American uses an average of 82 gallons of water at home every day, which costs the average family more than $1,000 a year. More than 30% of that water is used outdoors in lawns and gardens, but it can rise to as much as 60% in arid regions.

The EPA says that watering the average-sized U.S. lawn 20 minutes a day for one week is equivalent to leaving the shower running for four days straight. Given that at least one U.S. region undergoes significant drought each year, individuals and industries alike have good reason to minimize unnecessary water consumption habits.

From 2012 to 2016, California experienced a debilitating drought that caused more than 90% of the state to experience water deprivation. To ensure enough drinking water, Governor Jerry Brown ordered the first-ever statewide mandatory water restrictions in April 2015, requiring a 25% reduction in water use by cities and towns CANPR. The drought state of emergency was lifted in April 2017, but unfortunately, this was not a one-time occurrence.

As of June 2025, drought conditions persist across much of California and the southwestern United States. Approximately 39% of California remains under drought conditions, with southern California experiencing record-dry conditions at the start of the 2025 water year. In the broader Intermountain West region, which includes Arizona, New Mexico, Utah, Colorado, Nevada, and Wyoming, extreme and exceptional drought conditions have expanded from 20% of the region in March 2025 to 27% by May 2025, with the worst conditions in New Mexico and Arizona. The drought is expanding, with 24.86% of the U.S. and Puerto Rico, and 29.58% of the lower 48 states, experiencing drought conditions.

Go Gold

Water use increases greatly from June to September as warm, dry weather makes its way across the United States and water demand peaks. Excessive outdoor water use intensifies this demand. Many homeowners are making the shift to “go gold” by reducing the amount of watering during those crucial summer months and letting their grass turn from green to a seasonal gold.

Some cities and homeowners’ associations require proper lawn maintenance and green grass. But more and more green-minded municipalities are adopting the “go gold” model, saving tons of valuable water. If yours isn’t on board yet, let them know they should be.

Cutting back on personal water use not only saves money, but also benefits the environment by diverting less water from our rivers, bays, and estuaries. It lowers energy demand for pumping and treating water and reduces air pollution from busy wastewater treatment plants.

More Ways to Cut Down

If going gold isn’t on your to-do list, there are more options to reduce outdoor water use:

• Maintain Water Systems
  Nearly half of the water we use in our yards is lost from wind, evaporation, and runoff caused by inefficient irrigation systems, wasting more than 25,000 gallons of water each year. If you have an irrigation system — or even just a sprinkler — make sure to properly maintain it and check for leaks.
• Use Native Plants
  Because plants thrive in their native climate, they require minimal maintenance. Native plants need less water, fertilizer, and pesticides to grow. Climate-appropriate landscaping like xeriscaping requires minimal water but can still be lush and aesthetically pleasing.
• Go Grass-Free
  Who says houses need a bright green lawn? If you don’t want to let your grass go gold, think outside the box and create a grass-free landscaping design for your yard. Use things like beauty bark, native plants, and polished stones to spruce things up and virtually eliminate outdoor water needs.

Clean water is essential for life on Earth. Consider human and environmental health next time you reach for the hose.
