In this episode of Propaganda By The Seed we talk with rooftop gardener & permaculturist Mike Spade of the Plant The Seed Project. We talk about Mike's work in NY and Denver designing green roofs. Mike talk about the differences between growing with rooftop gardens in various climates and the crops that work well. We also get into some of the logistics to consider when building a rooftop garden and the challenges that one might encounter when growing food on rooftops, from hail to heat to rain and the soil's ability to hold water.
