O Christmas tree • Ready to get rid of your Christmas tree? Be sure to remove all lights, decorations, tinsel, stands and anything else that's artificial first. Christmas trees will be picked up curbside Jan. 4-31 in Cottonwood Heights, Holladay, Millcreek and other unincorporated areas. In Murray, trees can be dropped off through Jan. 31 at the main parking lot of Murray Park, 296 E. Murray Park Ave., and at Grant Park, 6150 S. Main St., in the west lot off Valley Drive. Midvale collects tree curbside during the two weeks after Christmas.
