Best Suited for These Uses/Sites
Zoysiagrass is used on home lawns, commercial lawns, golf course tees and fairways.


Moderate maintenance; good drought tolerance, irrigate as needed; mow at 1/2 to 1 1/2 inches; grass blades are tough and best appearance occurs when mowed with a reel-type mower; requires 1 to 3 pounds of nitrogen per 1,000 square feet per year and tolerates saline conditions relatively well; although grass is drought tolerant and will require minimal irrigation, irrigate when needed; produces much thatch, so periodic dethatching is required.


Plugs, which are expensive and slow to establish. Generally the plugs will spread and cover the area in one growing season when spaced on 6-inch centers; when placed on 12-inch centers, this process usually takes two growing seasons.



Refer to the National Turfgrass Evaluation Program (NTEP) website (www.ntep.org) for additional varieties and performance data atvarious locations. Look for trial sites and maintenance levels most similar to your own.
