Greenskeeper's roll of grass

SOD

Think of what’s laid down to instantly create a lush lawn or repair bare patches.

A greenskeeper maintains golf courses or lawns, and "roll of grass" hints at pre-cut sections of turf they might lay down. The word "sod" fits because it’s a common term for those grass patches, often sold in rolls for easy installation. There’s no hidden wordplay—just a straightforward definition where "greenskeeper" points to lawn care and "roll of grass" describes the answer directly.
