Turfgrass and Water Efficiency
Watering Tips

INTRODUCTION: SARAH LAVOY

Ms. LaVoy from the EPA began by introducing the relationship
between turfgrass and WaterSense. She pointed out that WaterSense
is not anti-turfgrass, but desires an efficient holistic use of turfgrass
along with other water-efficient practices in the landscape and
irrigation. She encouraged everyone to think critically about their
landscape needs, and think about a design that uses turfgrass as
throw rug in spaces where it can serve an intendent purpose, rather
than wall-to-wall carpeting. Ms. LaVoy continued to speak on the
challenges that water utilities face in securing and maintaining water
supply during peak irrigation periods in the summer, and how those challenges will be exacerbated with
climate change. She reiterated the need to be intentional in designing and maintaining outdoor spaces by
putting the right plant in the right place, and providing it with the right amount of water.

AWE UPDATE: RON BURKE

Following that, Mr. Burke spoke on the results of an evaluation that AWE had carried out on water utility
programs and market readiness for landscape transformations. AWE concluded that while many
homeowners are disconnected form their outdoor water use, they are, with the proper incentive, willing to
invest in water-efficient landscapes. Mr. Burke continued to cover useful resources available to AWE
partners including the Sustainable Landscapes: A Utility Program Guide and Learning Landscapes:
Outdoor Water Efficiency and Conservation Lessons.

FEATURED SPEAKERS: MR GEOFFREY RINEHART AND KEVIN MORRIS

Mr. Rinehart provided an overview of the benefits of turfgrass, the components affecting quality, and
common types of turfgrass by growing zone. He noted that turfgrass can provide several ecosystem
services when properly managed in a landscape. It can be an especially useful tool in urban areas to
mitigate the heat island effect, as well as create spaces that are culturally important in society. When
researching water-efficient turfgrass varieties, it is important to also weigh the performance in
recoverability, persistence, drought tolerance, uniformity, and color. All these desired traits and water

WaterSense-AWE Webinar Recap

requirements of turfgrass are dependent on the climate in which they are planted. Turfgrass varieties are
generally divided into three growing zones, cool, transitional, and warm, roughly based on latitudes and
climates in the US. Each zone will have different species that meet desired performance standards while
also meeting a level of water efficiency. Common cool-season grasses include, tall fescue, fineleaf
fescue, Kentucky bluegrass and perennial ryegrass. Common warm-season grasses include
bermudagrass, zoysiagrass, St. augustinegrass, and centipedegrass. Warm and cool-season grasses
often grow successfully in the transition zone but thrive during different seasons. Picking the right variety
of turfgrass for your local climate is a crucial part of a water efficient landscape in addition to proper lawn
maintenance.

Mr. Morris provided an overview of the National Turfgrass Evaluation Program (NTEP), which assesses
different varieties of turfgrass through an extensive 5 year testing process to evaluate grass performance.
NTEP coordinates with a broad array of partners including universities, the U.S. Department of
Agriculture, and turfgrass breeders. The program is currently testing more than 600 types of grasses from
20 species at testing sites located throughout the U.S. The data collected is used to determine the quality
of the grass based on scores given on a scale of 1-9. The characteristics evaluated include descriptive
characteristics, response to disease and pests, environmental stressors including cold and drought, and
how well the grass holds up under recreational use. This evaluation can help identify durable turfgrass
varieties that coupled with good management practices can be a part of a water-efficient landscape. Mr.
Morris briefly described efforts in Georgia and Texas to work with water stakeholders to identify types of
turfgrass that need less water and are more drought tolerant. He noted that all the reports on NTEP trials
are available to the public at ntep.org.

CONCLUSION

There are plenty of challenges facing water supplies in the US. The intentional use of turfgrass in a
landscape can still be part of a water-efficient landscape that helps lower peak water demands in the hot
summer months. Certain varieties of turfgrass are more suitable for specific climates than others and
growers are cultivating types of turfgrass that are more drought tolerant. Selecting the right plant for your
needs and local climate can contribute to a functional water-efficient landscape, and with proper
management, realize substantial water-savings.
