A study in 2016 showed that lawns are the largest irrigated crop in America. There are over 40 million grassy acres in the continental U.S., and they take a lot of water to thrive. But in the West, where rainfall is less plentiful, many water providers have been offering rebates to residents willing to tear out turf and replace it with drought tolerant plants. The programs are working and thousands of gallons of water are being saved. So why are two major cities punting on the idea? Our partners at H20 radio have the story.
