Members of the Professional Landcare Network were just some of the GIE+EXPO attendees that toured Churchill Downs in Louisville during the trade show and conference. The facility's horticulturist, John Backert, led the tour and explained that he grows most of the plants himself in a 12,000-square-foot greenhouse. Click here to take a photo tour of the grounds.
