A Chat with Wendi Bergin Greg Peterson and Wendi Bergin explore the “harvest mindset” and how to prepare for abundance before the garden starts producing more food than you can eat fresh. They discuss practical ways to preserve tomatoes, including freezing, canning, dehydrating, steam juicing, tomato powder, salsa, sauce, and tomato water. The conversation expands into zucchini preservation, fresh-milled grain, homesteading, preparedness, and the idea that being prepared can bring peace rather than fear. Throughout, Greg and Wendi emphasize experimenting, sharing ideas, and finding joy in growing and preserving local food. Key Topics Harvest mindset and preparing for garden abundance Preserving large tomato harvests Freezing tomatoes whole Water bath canning vs. pressure canning Safe, tested canning practices Tomato sauce, salsa, tomato juice, and tomato water Steam juicing and tomato powder Zucchini preservation, relish, fritters, and zucchini lasagna Fresh-milled grain and home baking Azure Standard bulk buying club Homesteading and self-reliance Preparedness as a source of peace Local food economies and growing your own food Basil preservation and pesto
Key Questions Answered • What is a “harvest mindset,” and why is it important? A harvest mindset means expecting abundance instead of being overwhelmed by it. If you plant 20 tomato plants, you may get very little—or you may get pounds and pounds of tomatoes. Preparing ahead of time allows you to enjoy that abundance rather than scrambling to figure out what to do with it. • What is the biggest mistake people make when harvest season begins? Not being prepared. Wendi recommends having your preservation equipment, jars, lids, and other supplies ready before the large harvest arrives. • What is a simple way to preserve tomatoes before the harvest gets really large? Wash the tomatoes, place them in bags, and freeze them whole. As the harvest grows, the frozen tomatoes can later be taken out and canned. • Why does tomato canning require added acid? The discussion explains that modern tomato varieties may not be acidic enough for safe water-bath canning without additional acid. Lemon juice is discussed as a way to increase acidity when canning tomatoes. • What is the difference between water-bath and pressure canning? Water-bath canning uses boiling water and is intended for sufficiently acidic foods. Pressure canning reaches temperatures above the boiling point of water and is used for lower-acid foods such as meats and vegetables. • What can you do with tomato water from a steam juicer? Instead of throwing it away, Wendi cans tomato water and uses it in stews, goulash, chili, and for cooking pasta. • What are some ways to use tomato powder? Dehydrated tomatoes can be blended into powder and used to thicken spaghetti sauce, flavor broths, add to roasts, make tomato paste or sauce, create spice blends, and make tomato soup. • How can you preserve a large zucchini harvest? Zucchini can be shredded, have its excess water removed, and frozen. It can also be made into relish or pickles, fritters, bread, and even a lasagna using sliced zucchini instead of pasta. • What is the larger lesson behind food preservation? Preparedness can bring peace and help people live above fear. Whether facing an emergency or simply an overwhelming garden harvest, preparation makes it possible to respond confidently and joyfully. Episode Highlights The harvest mindset starts before you have 50 pounds of tomatoes or zucchini. Freeze smaller tomato harvests as they arrive, then process them later when the volume increases. Being prepared means having jars, lids, equipment, and a preservation plan ready ahead of time. Preserve tomatoes simply by canning them as pure tomato sauce and adding herbs and spices later when cooking. Steam juicing can separate tomato juice from the solids, creating useful tomato water and concentrated tomato material. Dehydrated tomatoes can become tomato powder with doz

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.

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.
