Nothing can be quite as breathtaking as fall color, and though there's a certain poetry to this last burst of natural beauty before we plunge into winter, there's some hard science there, too. In this episode, Don and John talk about the chemical changes that make fall color happen and talk about their favorite fall color plants, shrubs and trees. Don fields a listener question about late fall pruning and we all seem to agree that slugs are, indeed, super gross.
