When maple trees experience the freezing nights and warm days of late winter, the sap starts to slowly rise. It's "Hort Friday" on Talk of Iowa, and we'll talk about maple syrup production. It's one of North America's oldest agricultural crops and there are a few commercial producers in Northeast Iowa. Guests are Richard Jauron, Iowa State University Extension Horticulture and Jesse Randall, Iowa State University Extension Forestry. We'll also answer your questions about the plants in your life.
