Growing Blooms in the Sky

In today’s BB Podcast Episode (No. 112), we’re visiting with Joanna Letz, owner of Bluma Flower Farm, a rooftop flower farm in Berkeley, California. If you’re intrigued by the thought of Joanna’s transition from traditional farming to rooftop farming (six stories up in the sky!), the unique challenges it presents, and the logistics involved, you’ll find this conversation fascinating.

Join us as we chat about:

  • The financial challenges faced by farmers
  • A variety of activities at Bluma Flower Farm (direct-to-consumer sales, weddings, events, teaching)
  • The transition from traditional farming to rooftop farming and designing floral arrangements
  • Some logistical challenges of farming on a rooftop (carrying materials, weight restrictions, quick-draining soil)
  • Challenges with irrigation and water management on the rooftop farm
  • Joanna’s background and career aspirations
  • The importance of taking risks and making changes for personal and professional growth
