Green Kyllinga

Green Kyllinga is also a perennial plant, but it encroaches in turfgrass environments through seed dispersal and the spread of underground rhizomes. This weed thrives in moist, poorly drained soils and can persist in full sun and moderate shade. This weed can be confused with yellow nutsedge, but it tends to form a denser patch of growth. The ability of kyllinga to tolerate low mowing heights makes it an issue for every playing surface on a golf course, including putting greens. Like yellow nutsedge, its growth rate can outpace the surrounding turf and cause aesthetic and playability issues.

They are native to Asia, favorable areas that have poor drainage or frequently wet.
