- <p>A breakthrough could save some ugly Sunbelt lawns
- </p>
- <p> For a suburbanite, few experiences are more wrenching than
- watching a lush green lawn turn brown and scraggly. All across
- the increasingly arid U.S. Sunbelt, homeowners are facing that
- disheartening prospect. Because of persistent droughts and
- rapid population growth, there is not nearly enough water to
- keep every plot of grass green. Los Angeles, in the fourth year
- of a dry spell, recently imposed water rationing, and South
- Florida, which absorbs as many as 1,000 newcomers a day, has
- been needing more rain for two years.
- </p>
- <p> But Sunbelters should not buy Astroturf just yet. Help may
- be on the way. Researchers at the University of Florida have
- developed a strain of grass so resistant to drought that in
- some locales, it may not need to be watered at all. The
- university's test patch, at a research center near Fort
- Lauderdale, is thick and green, even though it has received no
- water, except for an occasional rainfall, since March 1988.
- </p>
- <p> This new grass, called FX-10, is a variety of St. Augustine,
- the sod that is commonly used on the lawns of South and central
- Florida, the Gulf States and Southern California. But in
- contrast to the standard St. Augustine, which needs to be
- watered regularly, FX-10 (a cross of four African varieties)
- has an unusually deep root system--deep enough to tap into
- subsurface moisture in some areas. That makes it perfect for
- places like Florida, where the water table typically lies no
- deeper than about 5 ft. Moreover, FX-10 seems to use the water
- it gets more efficiently than other St. Augustine varieties do.
- In the drought-parched university plots where more than 60% of
- the standard St. Augustine has died, the patch of FX-10 has
- expanded in size by 8%.
- </p>
- <p> The project is funded in part by a $90,000 grant from the
- South Florida water management district, which is eager for a
- drought-resistant grass to be developed. Reason: officials
- estimate that half of the 800 million gallons of water
- delivered last year to the residents of the district's 16
- counties was used to sprinkle lawns.
- </p>
- <p> Though FX-10 shows enormous promise, it will not solve
- watering problems everywhere. Because part of its advantage
- depends on a reasonably shallow water table, even enthusiasts
- acknowledge that in certain locations--on hillsides, for
- instance, or in parts of the desert Southwest--the grass may
- require irrigation. Another limiting factor is temperature: as
- with other St. Augustine grasses, even a day below freezing
- proves deadly. Any place north of, say, Houston will not be
- hospitable.
- </p>
- <p> In South Florida, though, sod growers are confident of the
- new grass's potential. A total of 22 major growers,
- representing 85% of the state's St. Augustine grass-supply
- industry, have formed a cooperative venture that has obtained
- a license to begin cultivating FX-10. Since the grass does not
- proliferate rapidly, it will take a few years before growers
- can build up a big supply. But once FX-10 is in place on
- suburban lawns, the slow growth rate will offer several
- advantages to homeowners. They can skimp on fertilizer and will
- have to mow the grass no more than twice a month. And they may
- be able to throw away the sprinkler.
