Texas Tech scientists uncover new grass that's made for the shade
A Texas Tech University plant and soil science professor and a Lubbock nurseryman are about to cast a big shadow over Texas urban landscaping.
Rockwell Professor of Plant and Soil Science Dick Auld and his research team have scientifically characterized a new variety of hardy, drought-tolerant turfgrass that grows well under the shade of trees. The patent-pending grass variety will commercially be known as Shadow Turf, but technically it's a specially selected variety of Zoysiagrass that was discovered by Ivey.
"This university isn't an ivory tower," said Auld, who previously served as chairman of Tech's Department of Plant and Soil Science. "We reach out to local businesspeople all the time. This time we were able to get a new product out to the public and that's a real success story with economic impact to the university."
Texas Tech researchers have been working on ornamental turf grass breeding since 1994, with much of their efforts concentrating on buffalograss. Some four years ago the turf team produced Turffalo, a buffalograss for homeowners that's designed to be drought resistant with root systems sinking up to 10 feet into the ground, while retaining the density and true green color enjoyed with varieties like bermuda or fescue.
In the process of developing and marketing the new buffalograss, they were inundated with requests for some type of grass that would grow under the deep shade of trees. At the time the Texas Tech scientists were also working closely with Mark Ivey, the owner of Ivey Gardens Greenhouses.
In 2005, Ivey approached Texas Tech with a special variety of dark green Zoysiagrass that grew exceptionally well under shady conditions. Using Ivey's specimen, the Texas Tech researchers began the detailed task of developing a plant patent for Ivey's Zoysiagrass variety.
Led by Auld and graduate student Brad Sladek, they began the process of scientifically characterizing the grass. They developed trial plots detailing a comparison of the grasses' growth habits, locations where it would produce nationally and a DNA fingerprint identifying the plant. In addition, they looked at the cultural practices needed for it to grow well in Texas and across the region.
Last year Texas Tech's Office of the Vice President for Research presented Auld with a $40,000 grant to promote and commercialize the new grass variety. As part of a commercial agreement with Ivey, Texas Tech receives a portion of the royalties from sale of the grass.
"The patent was filed with the U.S. Patent Office in March and we're just waiting for approval," Auld said.
Introduced in the United States in the early 1900s, Zoysiagrass forms a dense turf when managed, Sladek noted. Native to China, Japan and other parts of Southeast Asia, the warm-season grass is well known for being extremely drought tolerant, nearly as salt tolerant as bermudagrass, and is among the most wear-tolerant turfgrasses.
Moreover, Sladek said it has the added feature of being cold tolerant, which allows it to be used on the South Plains. A number of our shade-tolerant, warm-season grasses, primarily St. Augustine grass, don't have cold tolerance, he said. That's why it's not often used in this area. Zoysiagrass really fits a niche here.
The Texas Tech researchers believe their new Shadow Turf will eventually have multiple applications from residential landscaping to golf courses. Right now, considering the way it is propagated, it will likely be first seen among homeowners.
Today, Shadow Turf is commercially sold in plug form. The 2x2x3-inch plugs, which are typically sold in $90 flats, are planted nine-to-12 inches apart depending on how quickly the homeowner wants to cover an area. The slow-establishing grass is normally planted from late May to early June.
"The beauty of this story is that here we had a small businessman trying to do something entrepreneurial and a major public university with scientific expertise that was willing to do something to help," Auld said. "That's why we have a commercialized product today."

Summertime is mosquito
Millions of biting, disease-carrying mosquitoes are buzzing around backyards, parks and neighborhoods this summer. You can reduce your chances of getting bitten by mosquito pests by helping to reduce their populations. Most female mosquitoes lay their eggs in standing water, so emptying pools of standing water is the best way to prevent future populations from hatching. Make sure to empty birdbaths and swimming pools at least once a week. Get rid of old tires, unused buckets and trash cans that can hold rainwater. Clean clogged roof gutters. Place a Mosquito Dunk in birdbaths and ponds. The active ingredient in Mosquito Dunks is a naturally occurring bacterium that kills mosquito larvae but isn’t harmful to other living things. A six-pack of Mosquito Dunks sells for about $10 at home centers, hardware stores and gardening stores.
"Flexible foam pipe insulation tubes make great toppers for wire tomato cages," writes Nancy Renwick. "Cut to appropriate length, open at the slit and place around top of wire cage. Tomato vines rest comfortably on the foam and not the harsh wire."

The traditional gypsy cure for hay fever was to pick fresh mint daily and place it in a cloth bag and sleep with it near your pillow. In two or three weeks symptoms were supposed to disappear. Early herbalists also prescribed mint for many upper respiratory diseases.
