The Appalachian Growers Seed Collective w/ Shelby Mandonado and Leeza Chen In this Episode Shelby Mandonado and Leeza Chen share the story behind the Appalachian Growers Seed Collective, a collaborative network of farmers producing and stewarding locally adapted seeds for the Southern Appalachian region. They discuss why regional seed production matters, how climate change makes local adaptation increasingly important, and how farmers can reclaim seed sovereignty by saving and sharing seeds. The conversation explores the practical realities of launching a seed collective, preserving heirloom varieties, and strengthening local food systems through collaboration rather than competition. It is an inspiring discussion about resilience, biodiversity, and the long-term power of community-grown seeds. Our Guests: Shelby is a farmer, organizer, and mother with a passion for collaborative models of community building based around our shared love of the land. And Leeza is a seed farmer near Asheville, North Carolina. She is inspired by the way seeds are both deeply personal and powerfully political, often leaning on them as a lens to understand our connection to the land, culture, and sovereignty.

Key Questions Answered What is the Appalachian Growers Seed Collective? A regional network of approximately ten farmers who collaboratively grow, steward, package, and sell locally adapted seed varieties while sharing equipment, knowledge, and resources. Why are locally adapted seeds so important? Seeds grown and selected in a specific region become better adapted to local climate, weather patterns, soils, pests, and diseases, improving reliability for future growers. What is a seed farmer? A seed farmer allows crops to complete their full life cycle, harvesting mature seed instead of edible produce, then cleaning, testing, and packaging seed for future planting. Why has on-farm seed saving declined? Commercial seed industry consolidation has led many growers to purchase seed annually rather than saving their own, reducing regional adaptation and local seed resilience. How did the COVID-19 pandemic influence the collective? Seed shortages during the pandemic exposed vulnerabilities in the food system and highlighted the need for local seed production and regional seed independence. How was the collective started? The founders secured a grant, purchased shared seed-processing equipment, built a mobile processing trailer, and spent significant time developing trust, shared values, and collaborative systems before expanding production. What makes Southern Appalachian seed production unique? The region's humid climate presents challenges rarely addressed by traditional seed-saving literature, requiring local experimentation and farmer-to-farmer learning. How can others start a regional seed collective? Begin with trusted growers, define shared values and goals, develop a complementary seed collection, share resources, and grow at the "speed of trust." How does the Utopian Seed Project support the collective? The nonprofit evaluates diverse crop varieties through research and field trials, then shares promising selections with the collective for regional seed production and distribution. What role does seed stewardship play in climate resilience? Saving seed from plants that survive local stresses gradually builds populations better adapted to changing environmental conditions. Can someone without a farming heritage become a seed steward? Absolutely. Every seed saver can become the first generation of a new seed lineage by preserving, sharing, and passing se

On this replay of the Rosie on the House radio show Host Rome and Farmer Greg welcome Rachel Opio, founder of Little Lighthouse Farm, a certified organic urban farm in central Phoenix, Arizona, to explore how growing food in small spaces can strengthen communities and reconnect people with the land. Inspired by her late mother, Lane Bales, Rachel transformed a family garden into a productive quarter-acre farm focused on soil health, biodiversity, fresh local food, and community education. She shares practical approaches to regenerative agriculture, companion planting, seed saving, and growing food in the Sonoran Desert. Rachel also explains how small urban farms can improve access to fresh produce, preserve growing knowledge, and contribute to a stronger local food system. Her advice for beginners is simple: start with one plant, grow something you love to eat, and let your garden grow from there.

With Seed Expert Bill McDorman Join us for our monthly live Seed Chat at SeedChat.org What makes a seed viable, and how do you know when it's ready to grow? In this episode of Seed Chat, Greg Peterson of the Urban Farm Podcast joins seed expert Bill McDorman to explore the art and science of harvesting mature, viable seeds from vegetables, fruits, and wild plants. They share practical techniques for saving seeds from cucumbers, squash, tomatoes, peppers, beans, lettuce, and more, explaining when to harvest, how to dry and process seeds, and why nature's built-in diversity matters. The conversation also explores the importance of seed saving, locally adapted varieties, and community seed networks in building a more resilient food system. Their message is simple: when in doubt, save the seeds and see what happens.

with Jennifer Miller & Erin Torgerson In this Episode - What if small farmers could build trust with their customers without taking on the cost and paperwork of USDA Organic certification? That’s the idea behind Certified Naturally Grown (CNG), a grassroots organization helping farmers show customers how they grow their food. In this episode, Greg Peterson sits down with Jennifer Miller and Erin Torgerson from CNG to talk about how peer inspections, transparency, and a strong farming community help make that possible. Along the way, they explore the importance of local food, saving seeds, sharing knowledge, and making good food more accessible to everyone. Our Guests: Jennifer is the interim executive director of Certified Naturally Grown. From working on farms around the world to running her own farm and directing two food hubs, Jennifer's hands-on experience proves one thing, food is her love language. Erin is the communications and certification coordinator of Certified Naturally Grown. While filming a student documentary about a local farm-to-table restaurant, Erin caught her first glimpse of a biodiverse small-scale farm and hasn't looked back. Certified Naturally Grown is an organization that offers peer review certification to farmers and beekeepers producing food, flowers, and fiber for their local communities by working in harmony with nature without relying on synthetic chemicals or GMOs. Key Topics Certified Naturally Grown (CNG): A farmer-led certification program built around trust, transparency, and community. CNG and USDA Organic: How CNG offers an alternative for farmers who find USDA Organic certification too expensive or complicated.

Farmer education and mentorship: How sharing experience can help new and established growers succeed. Understanding the food system: Why building a better food future involves more than just how we grow food.
In this Episode Farmer Greg welcomes returning guests Shawn and Beth Dougherty, homesteaders with 40 years of experience growing food and building a farm ecosystem with minimal outside inputs. They discuss their philosophy of homesteading, living soil, biological wealth, and the patterns that allow a farm to generate its own fertility and abundance. Their new book, One Cow Revolution, is an in-depth instruction manual for the family dairy cow, drawing on decades of experience with cows, goats, grazing, milk, and farm systems. Shawn and Beth have been homesteading for the last 40 years. They speak all over the country on sustainable farming, teaching whoever will listen how to grow food without inputs. They grow 95% of what they eat and what their animals eat, and the heart of their sustainable homestead is their grass-fed dairy cow. They joined us for the first time on episode 147 all the way back in October 2016.
