Tomatoes are the biggest income generators on a lot of market farms, so this week we’re nerding out on how to get the most out of your greenhouse tomatoes. We talk with Guillaume Lambert, co-founder of Orisha greenhouse automation, about how to get more from your protected tomatoes, ranging from low-tech options that don’t require heat, to some more high-tech solutions that require heat and automation to achieve. Even if you don’t have heated greenhouses, this conversation can help you decide whether or not it’s worth heating and automating in the future.

We start the interview with a bold claim- that many growers can double their tomato yields by implementing best-practices, including the right spacing, the right number of drip tapes and pulse irrigation, managing humidity and more. Disease management can be as simple as choosing resistant varieties to common GH diseases if you don’t have climate control, or you may be able to grow susceptible varieties if you have good climate control. We also discuss how to monitor plant growth and how to balance it between vegetative and generative growth. This discussion was sparked by our discussion of Orisha’s new greenhouse tomato course, which is available for free to the GFM audience through this link.

Kelley Rajala of Clear Lake Gardens in Aitken, Minnesota, shares what it was like to start a farm in California and then relocate to Minnesota in this interview with host April Parms Jones. Hear about moving the farm, and the differences between market farming in the two areas, with the new Minnesota location being much more rural than where they started out in the Santa Rosa area of California (e.g. there’s one stop light in the new county). Listeners can learn a lot from the process of finding customers in the new location, including outreach, building relationships with local markets, and introducing customers to new crops with promotions and events to get the community involved.

Kelley discusses the challenges and rewards of farming, the significance of crop diversification, and the need for resilience in the face of climate change. They also discuss the value of unusual crops like golden raspberries, the concept of food as medicine, and the joys and challenges of running a farm stand. Kelley offers strategies for how to educate customers about local produce, the benefits of being part of a farmers union, and the legacy of cooperative farming.
