What is typically the primary distinguishing factor between grass in the rough and grass in the fairway?

The primary distinguishing factor between grass in the rough and grass in the fairway is the mowing height. Fairways are typically mowed to a lower height, allowing for a close-cropped and smoother surface that facilitates better ball lies and playability. This constant low mowing encourages the growth of specific grass species that thrive under such conditions, providing a uniform playing surface.

In contrast, the rough is usually mowed to a higher height, which allows the grass to grow taller and thicker. This leads to a less maintained appearance, as the higher grass can provide more difficulty for a player trying to play their ball from this area. The height of the grass not only affects the playability but also influences the overall maintenance practices on the course.

While factors like grass species, soil type, and water requirements can also differ between the rough and fairway, the mowing height is the most immediate and visually apparent difference that players will experience during their game.
