In this episode, hear about growing cut flowers six stories above the San Francisco Bay Area with Joanna Letz of Bluma Flower Farm. Hear what it’s like to grow flowers in a bustling metropolis, differences between field and rooftop growing, and some of Joanna’s favorite varieties. We discuss the advantages and challenges (yes, there are weeds up there) of farming on top of a building in the city. As both farmers and cities realize the benefits of urban agriculture, hopefully there will be more opportunities for growing crops on rooves, and we hope this episode will give growers the confidence to make the leap!
