They regularly mow, water, fertilize, and aerate the fields. In addition, groundskeepers apply chemicals and fungicides to control weeds, kill pests, and prevent diseases.

Workers who maintain golf courses work under the direction of golf course superintendents and are called greenskeepers .
Greenskeepers do many of the same things other groundskeepers do.
In addition, greenskeepers periodically relocate the holes on putting greens to eliminate uneven wear of the turf and add interest and challenge to the game. Greenskeepers also keep canopies, benches, ball washers, and tee markers repaired and freshly painted. Some groundskeepers specialize in caring for cemeteries and memorial gardens. They dig graves to specified depth, generally using a backhoe. They may place concrete slabs on the bottom and around the sides of the grave to line it for greater support.
