Rethinking zoysiagrass for home lawns

K-State, Texas A&M develop new cold-hardy variety for home landscapes and golf courses

May 31, 2019

OLATHE, Kan. – Who doesn’t love the look and feel of a soft, green carpet of grass underfoot? Even better if it’s resistant to pests and requires less fertilizer than other grasses. A Kansas State University professor believes that zoysiagrass can fit the bill for home landscapes – even in Kansas and surrounding states.

Zoysiagrass is well known as a warm-season grass commonly grown across southern tier states for its dense, weed-resistant and slow-growing nature (think less mowing), plus it requires about half the water needed for cool-season grasses typically grown in the nation’s midsection.

Those who choose to grow zoysia should be aware, however, that as a warm-season grass, it goes dormant and turns brown in mid-October and may not green up again until late April.

“The determining factor for whether any warm-season grass that can be used here is winter survival,” said Kansas State University horticulture professor Jack Fry.

Kansas and other states across the middle of the country are in what’s called a transition zone, where both warm- and cool-season grasses can grow but weather extremes can prove challenging and sometimes injure or kill the grass. In order to improve on a longtime favorite zoysia called Meyer, Fry and his K-State colleagues teamed with Texas A&M Agrilife researchers to develop a new zoysia cultivar.

Their aim was to develop a cultivar that is as cold-tolerant as Meyer for areas in the transition zone, but also to offer improved characteristics, such as finer leaf blades and even better density which blocks out weeds.

The K-State team worked with Ambika Chandra, associate professor at Texas A&M, to develop a new hybrid that was ultimately named Innovation. The new hybrid can withstand the cold that can sometimes blanket the central U.S. as well as Meyer does, but also exhibits better quality, meaning it has a darker green color, finer leaf blades, better density and good uniformity.

Zoysiagrass is already widely used on golf course tees and fairways in Kansas and across the transition zone, but less so on home lawns, Fry said. When drought water restrictions come about, however, it’s a good choice for home lawns.

Zoysia, and especially newer cultivars like Innovation, also require less fertilizer or pest treatments to stay healthy than typical cool-season grasses such as tall fescue or Kentucky bluegrass.

To develop the new cultivar, the researchers used traditional plant breeding, crossing cold-hardy types with other southern-adapted types that offered high density and finer-textured leaf blades.

That density results in almost no herbicides being needed during the growing season, Fry said.

To get from initial crosses – about 1,500 in all – to the final product took about 13 years, Fry said. Along the way from those initial crosses, 35 looked promising, so were planted in 5-foot by 5-foot plots in Kansas and Texas and evaluated by the researchers, who then narrowed the list to seven.

Those top seven hybrids were tested at additional sites across the transition zone in Missouri, Oklahoma, North Carolina, Tennessee and Virginia. The result is Innovation, which was released for commercial growth and sales in 2015. It is currently available via licensed distributors through a company called Sod Solutions, which has sub-licensed production to 15 sod producers in eight states.

What’s next? A new phase of the K-State-Texas A&M research is under way which aims to identify grasses that have superior resistance to a disease called Large Patch, and there may even be types that are promising for use on golf greens, too, Fry said.

Sidebar: K-State has tie-in with longtime zoysia favorite

OLATHE, Kan. -- For many years, cold-hardy Meyer was the go-to grass for anyone wanting to grow zoysia in the U.S. transition zone between where warm-season and cool-season grasses work best. Kansas State University has an interesting tie-in with Meyer zoysia, according to K-State Professor of Horticulture Jack Fry, who related this story.

George Fairchild served as K-State’s president from 1879 to 1897. His son David earned bachelor’s and master’s degrees at K-State. David married Marian Bell, the daughter of Alexander Graham Bell, inventor of the telephone. After finishing his studies, he was hired by the U.S. Department of Agriculture as a plant explorer and eventually, head of the Office of Seed and Plant Introduction.

David Fairchild hired Frank Meyer to explore plants in Asia. Meyer took several trips in the years from 1908 to 1918. Several years later, Palemon Dorsett and William Morse followed Meyer on an extensive exploration trip. In addition to collecting soybean and seed from other grasses on that trip, the pair apparently collected Meyer zoysia seed in Kanggye, North Korea.

The seed was returned to Arlington Turf Gardens near Washington, D.C., now home of the Pentagon. Fry noted the irony that seed collected in North Korea was evaluated for use in the United States at the same site where the U.S. Department of Defense is now headquartered. The best of the grasses evaluated was named Meyer, in honor of Frank Meyer’s early efforts in plant exploration.

According to Fry, Meyer zoysia has been widely used as a vegetatively propagated cultivar since its release in 1952, overseen by Fred V. Grau, an acclaimed scientist with the U.S. Golf Association.

A further tie-in with Kansas occurred when in 1967, Mel Anderson, a member of the Golf Course Superintendents Association  of America (GCSAA) decided to sprig Meyer zoysia at Alvamar Hills Golf Course in Lawrence, Kansas, making it the first golf course in the U.S. to establish Meyer from its inception. Alvamar Hills is now the Jayhawk Club. Meyer zoysia then gained popularity as an excellent turf for fairways and tees in the transition zone climate, Fry said.
