Buzzword: Water-Wise Landscaping
What does it mean? Water-wise landscaping refers to the cultivation of lush, beautiful yards that require minimal irrigation. You might also see it referred to as xeriscaping, especially if you live in the southwestern United States, where the practice gained traction in the late 1970s. Xeriscape is actually a trademark of the Denver Water utility, so water-wise landscaping has emerged as the generic term.
Why the buzz? Water conservation is one hot topic, especially now that half of all U.S. states are in some level of drought condition, according to the National Weather Service. (Refer to the U.S. Seasonal Drought Outlook map to see which states are the driest. The map shown here was released on March 20, 2008.) And the water issue is only going to become more prominent. “Within the next 10 years, more than two thirds of the states in the nation will likely be short on water—even under non-drought conditions,” notes the U.S. Environmental Protection Agency in a brochure on water-efficient landscapes.
Water-wise landscaping goes beyond lawn care. In fact, one of its key goals is to minimize the amount of turfgrass in yards by incorporating less-thirsty plants, including groundcovers and ornamental grass, and dry elements like patios and gravel gardens into the design plan.
In our latest report on lawn care (in the May 2008 issue of Consumer Reports, on sale and on ConsumerReports.org the week of April 7), we talk about the need for smart watering practices, noting that half of the water applied to residential yards is lost to evaporation, wind, or run off. The rule of thumb for lawn irrigation is to water deeply but infrequently, and to always water in the morning, when the winds are calm and temperatures aren’t so hot that the water will evaporate before it reaches the roots. Remember, grass is ready for a soak only if you leave footprints when you walk across it.

Just a note about the lawn watering advise given in this article.
I have been practing newer avdice given to me by the State of Mich. Extention service. They recommend watering dailey 1/8 to 1/10 of water before the hotest time of the day. And not soaking the lawn as most people advise. They told me that you only must prevent the crown of the grass root from drying out during the hotest period of the afternoon, to keep it green. And that grass does not need much water to grow, but it goes into a dormant state if the crown gets dry for to long a time. This will make it turn brown and look dead. Its a protection state that keep it alive and that most other plants can't duplicate. I have been following this watering advice for over 10 years and I have the greenist lawn around most of the time. Before this I was soaking weekly or more often and still had browning problems. Watering late or early morning, you must soak the ground with enough water to last thru the entire day, because it starts evaporating early in the morning. By the hot period it is gone unless you use a great amout of water. This method works the best for me and conserves water and cost for me. In desert areas like Las Vegas, they water many times a day sometime houly, but maybe only a couple of minutes at each watering. But this keeps the crown of the grass root most and it stays green. Thats' all that nessessary. Grass does not require a big drink of water like waterlillys do.
I hope you pass this information along to all the frustrated lawn soakers with high water bills. I used to be one myself. Thanks, Gary Sadler, Lambertville, MI
