The Urban Farm Podcast with Greg Peterson

In This Podcast: Edmund Williams returns to discuss the LEHR Garden system and a breakthrough soil product emerging from it: LEHR Soil Amplifier. By combining ecological soil biology with engineered water flow, the LEHR system grows plants in primarily woody materials while composting beneath living roots. The resulting extracted soil behaves as a powerful biostimulant, dramatically improving plant growth, resilience, and heat tolerance. This episode explores living soil, stable carbon, and how feeding soil organisms transforms plant health.Our Guest: Edmund is a civil engineer and innovator in the urban and sustainable agriculture arena. He has been working with various municipalities and nonprofits to transform the ways our society feeds itself. The Lear Garden was designed to be a low maintenance system using biology as a part of the automation. To do this, Edmond created a compost bin as the core technology, and like any compost bin, it needs to be emptied periodically, The finished compost that comes out is unlike anything on the market having some very surprising and beneficial properties.Key TopicsLEHR Garden (Linking Ecosystem and Hardware for Regeneration)LEHR Soil AmplifierBiostimulants in agricultureLiving soil biologyStable soil carbonGlomalin and mycorrhizal fungiBiochar as nutrient bufferUrban waste stream compostingFlood-and-drain raised bed systemsHeat resilience in desert gardeningSoil food webTall pot tree propagation methodWhat makes a LEHR Garden different from hydroponics or permaculture alone?It integrates both ecology and hardware, using a raised flood-and-drain system filled mostly with wood chips and organic waste, allowing plants to grow in living soil biology rather than inert media.Why does the garden soil need to be removed and reset?As woody materials break down, water flow slows, causing anaerobic conditions. Removing and resetting the soil restores oxygen flow and system performance.What is LEHR Soil Amplifier?It is the sifted, biologically rich soil produced inside the system, containing earthworm castings, biochar, microbial life, and multiple known biostimulant compounds.How is this different from regular compost?Unlike compost made separately, this material forms beneath living roots, encouraging creation of stable soil carbon compounds such as glomalin, which are critical to true topsoil structure.How much is needed to see results?Very small amounts are effective — about one gallon can treat roughly 1,000 square feet of garden space.What plant responses have been observed?Reports include greener lawns, higher vegetable productivity, improved pest and disease resistance, thicker rose petals, and rapid recovery of stressed trees.Can it improve heat tolerance?Gardeners observed lush summer growth during record heat, with plants surviving and producing through extreme desert temperatures.What is the underlying mechanism?The product stimulates soil biology, increases mycorrhizal activity, provides mineral buffering through biochar, and enhances nutrient cycling.Episode HighlightsLEHR stands for Linking Ecosystem and Hardware for RegenerationGardens grow food in mostly wood chips enriched by composting beneath rootsSoil removal became the “problem that was the solution”Sifted soil behaves as a high-density biological stimulantStable soil carbon forms directly through plant–fungal interactionsOne gallon treats approximately 1,000 square feetGardeners report dramatic improvements during extreme heatTrees in tall pots showed accelerated growth using the amplifierCalls to Action & ResourcesLEHR Garden System — https://lehrgarden.comContact Edmund Williams — mailto:[email protected] Episode Show Notes Visit — UrbanFarm.org/SoilAmplifierNeed a little bit of advice or just a feedback on your design for your yard or garden?The Urban Farm Team is offering consults over the phone or zoom.

A Journey in Holistic WellnessIn This Podcast: Clinical herbalist Kimberly Kling returns to discuss regenerative health in a highly toxic modern world. Drawing from personal experience, clinical practice, and ecological awareness, she explains how petrochemicals, industrial agriculture, and environmental toxins disrupt human health—especially the gut microbiome, mitochondria, and detox pathways. The conversation moves from root causes to practical, accessible steps people can take, including food choices, herbs, lifestyle shifts, and community action. Throughout, the focus remains on empowerment, resilience, and reconnecting with plant wisdom rather than fear.Our Guest: Kimberly is a clinical herbalist and the guiding force behind joyful roots in Southern Arizona where she helps her community locally and beyond cultivate inner wellness through earth centered herbal care, rooted in a deep reverence for the healing power of plants. Kimberly's journey began in childhood, crafting magical plant stews and foraging connections with Michigan's native flora. Her background in landscape architecture and engineering provided a foundation for understanding the intricate relationships between plants, people, and the land. However, it was motherhood and a personal health crisis that led to her clinical herbalism deepening her passion for holistic wellness. Now, Kimberly integrates traditional wisdom with modern herbal practices, empowering others to reconnect with plant wisdom for vibrant health and wellbeing.Medical Disclaimer: In today's episode we are talking about our health.

A Rosie On The House ReplayIn this episode we explore the concept of wicking bed gardens, hosted by Romey Romero & Farmer Greg, our guest is .Farmer Greg joins Romey Romero on Rosie on the House to break down how to successfully grow fruit trees in the low desert, even during unusually warm winters. He explains why fruit trees are worth planting, how climate confusion affects citrus and deciduous trees, and the most common mistakes that kill young trees. The conversation covers proven planting methods, soil preparation, watering strategies, and long-term thinking for orchards that can produce for decades. This episode is a practical, experience-based guide for homeowners who want reliable fruit harvests in desert climates.Key Topics & EntitiesLow desert fruit tree growingCitrus varieties (navel, Cara Cara, Trovita, Minneola, Gold Nugget)Deciduous fruit trees (apple, peach, apricot, plum, jujube, mulberry)Low-chill requirementsRootstock selectionBare root treesUrban Farm Fruit Tree ProgramSix-Six Basin RuleDesert soil organic matterMycorrhizae and soil biologyIrrigation and deep wateringMulch and microclimatesKey Questions AnsweredWhy plant fruit trees instead of relying on store-bought fruit?Homegrown fruit has superior flavor, freshness, and nutritional value, and a single tree can produce for decades with proper care.What makes fruit trees struggle during warm winters in the desert?Low-chill trees may not receive enough cold hours to set fruit consistently, causing irregular growth, dormancy confusion, or skipped production years. Therefore, we need to make sure we plant low chill fruit trees.What are the three non-negotiables when buying fruit trees for the low desert?Choose low-chill varieties, ensure the correct rootstock for desert conditions, and select soft-flesh fruit that ripens before July 1.What are the most common ways people accidentally kill fruit trees?Planting in hot microclimates, allowing grass to compete with roots, and relying on shallow daily drip irrigation.How should fruit trees actually be watered in the desert?Deep, infrequent watering—about once a month in winter and every 10–14 days in summer—allowing soil to dry between waterings.Why are bare root trees preferred for deciduous fruit?They’re planted while dormant, establish faster, and adapt better long-term than potted trees when planted correctly.How long does it take for a fruit tree to really produce?Year one focuses on roots, year two on shoots, year three begins fruiting, and years four to five bring full production.Episode HighlightsFruit trees thrive when planted for climate, not convenienceCitrus can be harvested across six months with smart variety selectionThe Six-Six Basin Rule dramatically improves survival and growthDesert soil must be rebuilt with organic matter and biologyOverwatering and under watering look the same—but both can kill treesBare root planting in January sets trees up for lifelong successA single well-planted tree can produce for 50–100 yearsCalls to Action & ResourcesUrban Farm Fruit Tree Program — https://www.fruittrees.orgFree Desert Fruit Tree Master Course — https://www.fruittrees.orgQuestions or tree photos — [email protected] www.UrbanFarm.org/962 for the show notes and links on this episode!Need a little bit of advice or just a feedback on your design for your yard or garden?The Urban Farm Team is offering consults over the phone or zoom.

Our monthly Seed Chat at SeedChat.orgIn This Podcast: Greg Peterson and Bill McDorman explore the idea of the seed commons—seeds as shared cultural, ecological, and community wealth rather than private commodities. They discuss how market-driven seed systems have eroded biodiversity and why community-based models are essential for resilience in the face of climate, economic, and social uncertainty. Through stories, examples, and lived experience, they show how seed co-ops, exchanges, libraries, and grassroots experimentation restore abundance, adaptability, and human connection. The conversation frames seed saving as both a practical survival skill and a deeply human act of stewardship.Key Topics & EntitiesSeed commonsShared wealthBiodiversity lossClimate change adaptationSeed co-opsAppalachian SeedsSnake River Seed CooperativeSeed exchangesSeed librariesSeed Library NetworkSeeds in CommonOpen-pollinated seedsIndigenous and community seed stewardshipWhat does it mean to treat seeds as part of the commons?Seeds are framed as shared wealth—like air or water—meant to circulate freely so they can keep adapting, carrying cultural memory, and supporting future generations rather than being locked behind patents or profit motives.Why is the current market-based seed system failing biodiversity?Large-scale commercial systems prioritize uniformity and profit, leading to the extinction of many traditional varieties and reducing the genetic diversity needed to adapt to climate and ecological change.How do seed co-ops work in practice?Regional growers collaborate to grow, clean, package, and distribute seeds together, sharing labor and profits while keeping ownership local and ensuring regionally adapted varieties remain available.What role do seed exchanges and seed libraries play in communities?They provide accessible, low-cost ways for people to share seeds, stories, and growing knowledge, strengthening trust, local resilience, and intergenerational learning.What is unique about the Seeds in Common model?Instead of preserving varieties separately, Seeds in Common mixes many varieties together and distributes them widely, prioritizing real-world adaptation and survival over strict categorization or commercial naming.Can individuals really name and steward new plant varieties?Yes—historically, many important crops came from backyard growers. Naming and caring for a variety is an act of responsibility, not ownership, rooted in long-term stewardship rather than profit.Episode HighlightsSeeds as shared wealth are essential for resilience, adaptability, and cultural continuity.Seed co-ops like Appalachian Seeds and Snake River Seed Cooperative keep control local and varieties alive.Seed exchanges offer efficient, story-rich ways to share seeds and knowledge within communities.Seed libraries have rapidly grown worldwide, each shaped by local values and creativity.Mixing and growing diverse seeds reveals what truly works under local, low-input conditions.Naming and saving seeds is a deeply human tradition that predates modern agriculture.Abundance thinking emerges naturally when people engage directly with growing and saving seed.Calls to Action & ResourcesJoin live Seed Chats — https://seedchat.orgExplore regional seed co-ops — https://snakeriverseeds.com | https://www.utopianseed.orgLearn about seed libraries — https://seedlibrarynetwork.orgParticipate in seed sharing experiments — https://seedsincommon.orgVisit UrbanFarm.org/961 for the show notes and links on this episode!
