Why Are There White Dots Around The Edges of the Greens?

The golf maintenance department paints white dots around the greens to preserve the outer boundaries of the putting greens. These dots help guide our greens mowers around the edges of the greens to prevent expansion of the green or encroachment of the rough. This practice is also utilized around the edges of fairways and approaches to preserve crisp edges.
