scalping
n.— «Each autumn, Coachella Valley homeowners, golf course operators and landscapers replace summer Bermuda grass with winter rye in a process called scalping. Bermuda grass can withstand the desert’s summer heat; when it goes dormant, winter rye makes for the perfect replacement as it stays green when night temperatures fall below 40 degrees.» —“Lawn scalping: Unhealthy practice that needs to be discouraged” Desert Sun (Palm Springs, California) Oct. 4, 2005.
