Which turf zone is typically mowed at the highest height?

• A. Deep rough
• B. Putting green
• C. Fairway
• D. Fringe

Answer: (A)

The main idea here is how mowing height varies by turf zone. Deep rough is kept much taller than the other zones, so it’s mowed at the highest height. This deliberate tall growth creates a tougher, penalizing lie that makes shots from off the fairway slower and more challenging, which is a common design aim for rough. By contrast, putting greens are groomed very short for a smooth ball roll, fringes sit in between but closer to the green height, and fairways are kept shorter than the rough to provide a consistent, playable surface. So the zone mowed the highest is the deep rough.
