The Rhizoctonia solani fungus attacks zoysia grass and causes a disorder called large brown patch. Small, rounded spots of discolored, water-soaked grass appear on zoysia lawns.These damaged areas often have a yellowish ring of dying grass around their perimeters.oysia is a species of warm-weather grass native to Southeast Asia. Named after Karl von Zois, an 18th-century botanist from Austria, zoysia became popular with United States homeowners in the 1940s and 1950s, particularly in the southern United States, because these grasses perform well in warm climates.
Zoysiagrass Seed. Unlike perennial ryegrass and Kentucky bluegrass, Zoysia is a warm-season grass, meaning it germinates best when the temperatures are in the 70s or 80s. Typically germination time for Zoysiagrass seed is 10 days or more, so if you're not seeing growth by the time you hit the two-week mark, it's time to start worrying. Different lawn varieties will germinate at different times. Know how long your grass seeds should take, and the waiting will be much easier.
