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 maintenance and groundskeeping services industry in the United States in 2006. Of these over 300,000 workers were greenskeepers for golf courses, schools, resorts, and public parks.[1]
