Louie talks with John White, curator of the Chihuahuan Desert Gardens at the UTEP Centennial Museum. John gives us the lowdown on holiday plant care, including the care of poinsettias, Christmas cacti, and live or cut Christmas trees. He also talks about why we shouldn't sing the praises of the parasitic, poisonous mistletoe! John also fills us in on holiday snacks such as pecans, and why the drought is affecting the supply. Aired Dec. 15, 2012.
