Yellow tuft bentgrass and tall fescue are two different types of grass. Yellow tuft bentgrass is a fine-textured grass that is often used on golf courses, while tall fescue is a coarser grass that is commonly used for lawns and pastures. Yellow tuft bentgrass is more tolerant of low mowing heights and is often used on putting greens, while tall fescue is more tolerant of heat and drought.
