The Market Gardener Podcast

In this solo episode, Jean-Martin Fortier reveals the ultimate secret weapon for healthy soil and high-yield market gardening: cover crops and green manures. While beginner market gardens often focus strictly on profitable cash crops, long-term farm sustainability and profitability depend on embedding cover crop systems directly into seasonal crop rotations.
Jean-Martin explains how standard cover crops eliminate erosion by protecting bare winter soils, while legume-rich green manures supercharge on-farm fertility by injecting nitrogen and building massive subsoil root networks. He breaks down his practical, low-machinery techniques for terminating cover crops on permanent beds and you’ll discover how hitting the "golden ratio" of keeping one-third of your garden in cover crop at all times can drastically reduce external fertilizer inputs and unlock deep, long-term soil ecology.

In this episode, we sit down with Elspeth Hay, Cape Cod journalist and author of Feed Us with Trees, to explore how we can solve our collective separation from nature through the power of tree crops. We dive deep into her journey from learning the “no farms, no food” mantra in childhood to the paradigm-shifting realization that our surrounding forests are actually overflowing with staple foods like acorns. Elspeth deconstructs historical narratives like the term "hunter-gatherer" and the concept of "enclosure," arguing that modern industrial farming models were built upon a violent legacy of privatizing land and erasing highly managed indigenous food systems. The conversation highlights how traditional communities managed ecological resources collectively through the "Commons" and specific cultural rituals. Finally, we discuss how local communities can reverse the "shifting baseline syndrome," her advice on cultivating ecological joy and rituals for the next generation, and her vision of a future rooted in regional food resilience and connection to community and place.

In this episode, we sit down with Sam Knapp, an Alaskan grower and author of Beyond the Root Cellar, to explore what it means to solve the biggest gaping hole in the local food system: winter food security. We dive deep into his journey from chemical engineering and a formative Fulbright grant in Sweden to establishing a successful, low-overhead storage crop farm in Fairbanks, Alaska. We highlight how Sam built a highly viable business on 1 acre by focusing on low-maintenance root crops like parsnips and utilizing efficient, manual systems instead of heavy machinery. Sam breaks down the structural design of his self-built cold storage facility, tips for managing humidity with Inkbird sensors and thermostats, and the reality of fighting thermal mass in the ground. Finally, we discuss how local growers can build predictable, highly profitable “off-season” revenue, his advice on avoiding the "YouTube Academy" trap by finding mentors, and his ultimate mission to democratize cold storage for local communities.

In this episode, Jean-Martin and Chris sit down with Jessica Paige of Adama Farm to discuss her journey from university student to first-generation regenerative farmer and influencer. Jessica explores the importance of "romanticizing" farm life, explaining how finding beauty in the intensive labor makes the work more enjoyable and sustainable, and how sharing this beauty online can inspire new young people to get into farming. She reflects on her formative apprenticeship at Frith Farm, her spiritual awakening through nature, and the empowerment of leading an all-female crew. The conversation covers the practicalities of starting a farm, from land acquisition to navigating the "year two and three" hurdles of infrastructure and irrigation. Ultimately, she highlights how a small-scale farm can become a vibrant community hub through farm-to-table dinners and shared connection to the land.
