Whether you already grow mushrooms or are looking to diversify your market offerings, Erin Hamilton of The Mushroom Conservatory tells us about the varieties and methods we should consider for mushrooms that can be cultured and grown for market. Erin, an expert mushroom grower and agricultural educator, shares her passion for mushrooms and their ecological significance, including how spent mushroom spawn can improve your compost pile. She discusses the role of mycelium in plant growth, types of mushrooms you can cultivate, and the ongoing debate surrounding golden oyster mushrooms.

Erin also provides practical advice on how to start growing mushrooms, focusing on oyster mushrooms and functional varieties. She provides a detailed guide on growing mushrooms, discusses the health benefits of functional mushrooms like Lion's Mane, and offers practical tips for selling mushrooms at farmers markets and building relationships with restaurants. This includes ways to dehydrate and package mushrooms that come back from market for sale later in this conversation with host April Parms Jones.

Dave Chapman tells us about the origins of the Real Organic Project, and why preserving organic standards is important for all growers whether certified organic or not in this week’s podcast. Dave is the co-director of the Real Organic Project (ROP) and owner of Long Wind Farm in Vermont. The ROP is active in preserving the standards of the National Organic Program (NOP) in the face of lobbying by agribusiness to relax them, particularly in the areas of allowing hydroponics to be certified organic and enforcing animal welfare standards in organic production.

This is the first of a two-part conversation about the ROP, this one focusing on hydroponics and the forthcoming episode will focus on preserving animal welfare standards. Dave highlights the impact on consumer trust that comes from weakening the NOP, and the future of organic standards as corporations push for changing them. The conversation also touches on the challenges posed by container production and herbicide use in “organic” farming, the health impacts of chemical agriculture and the growth of the Real Organic Certification initiative.

Diane Szukovathy of Jello Mold Farm tells host Rebecca Kutzer-Rice how the need for standards for floral crops at the Seattle Wholesale Growers Market (SWGM) led to the creation of the new book Floral Standards: A Practical Guide for Harvesting and Delivering Professional Quality Products. They also discuss Diane’s journey in flower farming, the establishment of the Seattle Wholesale Growers Market, and the importance of quality standards in the floral industry. Diane highlights the collaborative efforts of local growers to create the Floral Standards book, which serves as a comprehensive guide for harvesting and delivering the highest quality flowers.

The discussion also covers specific crops like dahlias, hellebores and sweet peas, emphasizing the need for careful handling and understanding of harvest stages to ensure product quality.

Started in the late 1980s by Sandy and Paul Arnold, Pleasant Valley Farm in Argyle, New York, helped innovate and share winter growing techniques that lengthened local food season on many market farms. After decades of selling at farmers markets, during the pandemic they switched to online sales only out of necessity. Listen to this interview with their son Robert Arnold to find out how they made the transition on short notice, why they never went back to farmers markets, and tips from how they manage their 100% online sales.

We also get some tips from the farm, including an innovative method for long-term storage of head lettuce. In addition to growing up and working on Pleasant Valley Farm, Robert has his own business called Smart Farm Innovations that helps farmers automate tasks around the farm. Robert tells us how and what processes farmers are automating to save time and gain peace of mind.

Farm Action is a nonpartisan agricultural watchdog organization led by farmers, and Research and Policy Development Director Sarah Carden joins host April Parms Jones to discuss how they provide food-system accountability for farmers. Farm Action advocates for a fair and sustainable food system that empowers farmers and rural communities by focusing on holding large corporations and the government accountable for their actions in agriculture. Hear why specialty crop producers often receive less support compared to commodity crops, and the impact on food pricing and diversity, which is part of the reason why processed foods are often cheaper than vegetables.

United States food and agriculture policies currently enable a handful of the world’s largest corporations to control our food and farming system at the expense of farmers, workers, and all of us who eat. Hear how Farm Action encourages consumer awareness and education about food labeling as essential parts of supporting local agriculture, and advocates for accountability from both our government and large corporations within the agricultural sector.

Have you ever thought of a project that would be perfect for your farm, except that it’s not profitable? It might be possible with a for-profit/nonprofit partnership! In this episode we explore these partnerships with Amber Lambke, cofounder and CEO of Maine Grains. We’ll hear how such a partnership helped her start a gristmill in a repurposed Victorian-era jailhouse, which has spurred the revival of grain production in Maine.

Amber shares insights on the challenges of building a business in a rural area, the complexities of funding agricultural projects, the role of nonprofits in supporting local economies, and the implications of tax laws on grant funding. We explore innovative funding models to enhance agricultural sustainability and food security, the intricacies of forming and operating a nonprofit organization, the importance of having a clear mission, understanding the legal requirements for nonprofit status, and the challenges of securing funding through grants. As an example, interviewer and GFM editor Andrew Mefferd describes a greenhouse project for his farm to see if Amber thinks it might be a good candidate for such a partnership.

With a background in management and education, it wasn’t always obvious that Tyrean Lewis would become a farmer. But after taking stock of how few options there were for healthy food in his area, he decided to start a farm in the city of St. Louis, Missouri. Coming from a long line of farmers, Tyrean is the fifth generation of his family to farm.

In this interview with host April Parms Jones, Tyrean tells us how he founded his first farm on a vacant lot, and that farm was so successful that he has continued to expand it. There are lots of great tips in this interview whether farming in urban areas or not, including how to find a good farm site and how to improve the soil using materials like compost and leaves that may be available for free. He also shares a lot of great ideas for how to network with the community regardless of whether you’re looking to establish a farm or a market, and explains how their farm incubator program is training the next generation of farmers.

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.
