What it does it take to run the horticulture program at a zoo? Find out on a fascinating episode of We Dig Plants as Carmen DeVito and Alice Marcus Krieg are joined by Frank Pizzi, Curator of Horticulture at Pittsburgh Zoo and PPG Aquarium. They discuss exhibit design within zoos and how horticulture plays a role in that. Learn about the tricks that are used to mimic natural habitats of animals in zoos! This program was brought to you by Whole Foods Market. We do a lot of smoke and mirrors so it looks like they can get at the plants but they cant. Its magic, actually. [13:00] Hot dry air and tropical plants is a nightmare waiting to happen. [21:00] --Frank Pizzi on We Dig Plants
