Groundskeeping is the activity of tending an area of land for aesthetic or functional purposes; typically in an institutional setting. It includes mowing grass, trimming hedges, pulling weeds, planting flowers, etc. The U.S. Department of Labor estimated that more than 900,000 workers are employed in the landscape and groundskeeping services industry in the United States in 2006. Of these over 300,000 workers were groundskeepers for golf courses, schools, resorts, and public parks. Compare gardener.
A groundskeeper is a person who maintains landscaping, gardens or sporting venues (and their vegetation where appropriate) for appearance and functionality. In Britain the word groundsman (occasionally groundswoman if appropriate) or park-keeper is used much more commonly. In Australia, the word curator is often used for a person undertaking this job, especially those involving cricket pitches. At university campuses, groundskeepers are often called horticulturists. The equivalent on a golf course is a greenskeeper.
The U.S. Bureau of Labor Statistics (BLS) estimated in May of 2015 that statistical group 37-3011 "Landscaping and Groundskeeping Workers" numbered 895,600 with a median annual wage of $25,030. The BLS desscribes the functions of this group as "Workers typically perform a variety of tasks, which may include any combination of the following: sod laying, mowing, trimming, planting, watering, fertilizing, digging, raking, sprinkler installation, and installation of mortarless segmental concrete masonry wall units".
Usage examples of "groundskeeping".
Two windows were driven in by hail, and the windstorm picked up a low picket fence surrounding a quaint little gazebo on the far side of the duckpond and threw it sixty yards, but that was the extent of the damage (except for flying branches and some ruined flowerbeds-more work for the groundskeeping force).
