Creeping bentgrass is a spreading cool-season perennial grass that is commonly used for golf course greens, tees and fairways. Like other grasses, bentgrass can be considered a weed when it is present in another species.
Because bentgrass spreads by stolons, it is possible for bentgrass to encroach adjacent turf areas. Irrigation is almost always required for bentgrass to survive beyond where it is planted.
Bentgrass becomes very 'puffy' when maintained at mowing heights above one inch.
