Creeping bentgrass (Agrostis stolonifera) is the most widely used cool-season grass on golf course putting greens. It is a fine-textured species that can tolerate close mowing heights and spreads by stolons. This allows it to recover from traffic and golf ball marks. However, it has very high maintenance requirements including fertilization, topdressing, mowing, and frequent fungicide applications, particularly during the summer months.
