This week on We Dig Plants Carmen hosts the monthly fruit episode on apples. Steven Hoying of Cornell University calls in to explain how apple growers have kept their trees disease and pest free, why apple trees are genetically promiscuous, and why those bright red apples from the cafeteria taste so absurd. Tune in for an episode on orchards, hard cider, and apple pie from The Big Apple. This episode was sponsored by Hearst Ranch: purveyors of fine grass-fed beef from the California coast.
