Green going out of fashion in California

Many Californians are beginning to reluctantly accept that a well-manicured, lush green lawn is no longer a realistic landscape feature in the arid West, reported Steven Kurutz in the New York Times.

Chuck Ingels, UC Cooperative Extension advisor in Sacramento County, told the reporter homeowners with traditional green lawns may soon have no choice but to let them go brown. An average of 50 to 60 percent of a household's water consumption goes to outdoor use, which includes the landscape. He envisions a future in which lawns go dormant in winter and in summer, if watering is not allowed.

“The water bills are going up,” Ingels said. “I think we're going to start seeing more and more people opt for a brown lawn. I think it could become more traditional.”

If some water is available, there are less thirsty alternatives to traditional lawns that can provide a similar effect. Ingels has experimented with meadow-like buffalograss and dune sedge as alternatives. For example, UC Verde buffalograss, released in 2003, was bred for the California climate by UC researchers. It needs only infrequent mowing, uses half the water of tall fescue and is disease and pest resistant.

Other options are drought-tolerant native species like carex and bentgrass. These can be used for the meadow effect if not mowed, or mowed regularly for a more traditional look.

Water-efficient plants highlighted at turfgrass event

Reporter Laurie Lucas covered UC Riverside's turfgrass field day for The (Riverside) Press-Enterprise. Approximately 200 homeowners, park managers, water experts, scientists, nursery professionals and golf course supervisors attended the event. One of the 13 projects highlighted at the Turfgrass Research Facility's event examined water-efficient groundcover, including rosemary, thyme and iceplant. UC Cooperative Extension specialist Donald Merhaut commented on the plants' response to reduced water. "Most of the 18 species we grew with limited irrigation did well," he told the reporter. "But the geraniums showed the most direct heat stress." The article also highlighted trailing purple lantana, blue rug juniper, honeysuckle, vygie, grey saltbush and morning glory as other alternatives for cool-season grasses.

PopSci pursues the perfect lawn

Popular Science, the world's largest science and technology magazine, spotlighted the work of UC Riverside Cooperative Extension turf scientist Jim Baird in its May 2010 "Statistically Speaking" feature. Titled "The Perfect Lawn," the full-page story said Baird is bioengineering grass that drinks less water and still earns praise for its lush, emerald green appearance.

"The process is sort of a gladiator academy for grass," PopSci says. The scientists grow promising hybrids, then turn off the water to see which ones survive.

The article opens with statistics on turf grass' ability to sequester carbon. U.S. lawns, it says, could trap enough carbon each year to offset the emissions from burning 1.9 billion gallons of gasoline. However, it takes 7 billion gallons of water a year to keep the grass green.

Other statistics in the feature were:

• 625 square feet - Area of lawn needed to make enough oxygen for one person for one day
• 1.57 billion hours - Time homeowners spend mowing the lawn per year
• 37 billion pounds - Carbon dioxide that residential lawns can store per year
• 800 million gallons - Amount of gas guzzled by lawn mowers annually
• 33,000 square miles - Area of the U.S. covered by residential lawns

What is the value of a feature in Popular Science, a magazine with a 1.3 million monthly circulation? Stories are probably better-read than ads, and a full-page, four-color ad costs $124,135, according to the magazine's published rates.
