What does the PGA require for a golf course's total area?

The correct answer highlights that the total area of a golf course must be entirely planted in grass. This requirement underscores the importance of maintaining a suitable playing surface and environment for the sport of golf, ensuring that the course provides optimal conditions for play. Grass is essential for various reasons, including aesthetics, the playability of the course, and the overall experience for golfers. Different types of grass can be utilized in different areas of the course to suit climate and soil conditions, but the fundamental requirement remains that the course is predominantly composed of grass areas.

The emphasis on turf is critical as it contributes to the health of the course ecosystem, aids in water management, and provides footing stability for players. Properly maintained grass areas also play a significant role in the game's traditional values and standards. As a result, a golf course must prioritize being planted in grass to align with both the professional standards set by the PGA and the expectations of the golfing community.
