Putting greens on golf courses are the highest maintenance turfgrass that exists. Creeping bentgrass (Agrostis stolonifera L.) often is used for cool-season putting greens due to the ability of the turfgrass to tolerate a low mowing height and provide a high density turf. Managing organic matter is necessary to maintain a high quality turfgrass at 0.125 in. height of cut that will drain quickly after a rain to resume play.
