Episodes
  • Nutrients, Fertilizers, Microbes, Living Soil and Manure
    Mar 24 2026

    In this lively episode of the Dirt on Gardening, we're joined by special guest Nate from Classy Rabbit to continue our deep-dive into plant nutrition—especially the often-overlooked micronutrients. We swap weekend updates (RIP to a towering mango, congrats on Gray’s upcoming Home Depot miniseries, and Derek’s studio reset), then dive into practical, myth-busting guidance on NPK vs. micros, fertilizer antagonism, diagnosing leaf symptoms (like purpleing from potassium/magnesium issues), and why soil biology and structure must come first. Nate explains why rabbit manure is a standout “cold” amendment, how to use and even grind it for faster availability, and the importance of complete, carbon-rich mixes that support microbial life. We tackle real-world questions on sulfur water, chloramine in tap water, coffee grounds, alocasia potting mix, baby shampoo vs. dish soap for pests, and more—while keeping it playful and straight to the poop.

    Key takeaways: don’t overdo micros, but don’t ignore them; prioritize living soil over quick nutrient hits; watch for nutrient interactions; and use simple, proven practices (like balanced mixes, appropriate manures, and mild soapy sprays) to help plants thrive.

  • From NPK to Microbes: Building Healthier Roots (and Fewer Gnats)
    Mar 17 2026
    In this episode of The Dirt on Gardening, we’re joined by Tiffany Davis, creator of Thryve Roots, for a lively deep-dive into soil health. We unpack the basics of NPK (nitrogen for leafy growth, phosphorus for roots/flowers, potassium for overall vigor), why nutrient mobility matters after heavy rains, and how soil amendments and microbes improve nutrient uptake and water retention without encouraging overwatering. We also touch on pollinator-friendly practices, terpene profiles, and practical propagation tips using moss and amendments. Beyond the science, we swap weekend stories—from unexpected wildlife on the golf course to campus talks at NC State—and answer rapid-fire community questions: fungus gnat control with BTI “tea,” propagating woody cuttings (including cherries), and dialing in seed-starting mixes with coco coir, peat, and perlite. By the end, you’ll have a clearer roadmap for balancing fertilizers with amendments and a teaser for part two on often-overlooked micronutrients.

  • Freeze Fallout, GMO Facts, and the Weirdest Plant Truths You Didn’t Know
    Mar 10 2026

    In this episode of The Dirt on Gardening, join us for a lively, wide-ranging conversation on weird and wonderful plant facts—and real-world garden recovery after Florida’s rare deep freeze. We share firsthand observations of mangoes, bananas, lychees, and avocados taking a hard hit, what to expect from bananas rebounding next season, and why this year might be a lighter workload in my orchard. From there, we dive into myths and truths about GMOs (papaya history in Hawaii, “Roundup Ready” context, and separating tools from companies), the psychology and history of tobacco and smoking culture, and fun clarifications like why baby carrots are a marketing win, the portobello–button mushroom connection, and how cilantro and Brussels sprouts taste can be genetic. We also explore plant science nuggets—corn as grass/seed/fruit, nuts vs. legumes (peanuts, cashews, coconuts), space-grown potatoes, gravitropism vs. geotropism, and a quick primer on aeroponics. Listener Q&A covers fungus gnats in water-rooted garlic, timing sweet potato slips, zone-based mango tips, and growing jackfruit and hibiscus sabdariffa (sorrel). Plus, we shout out community stories, swaps, and upcoming guest Tiffany from Thrive Roots next.

    Resources and mentions: aeroponics basics; sorrel/roselle growing tips; mosquito bits/dunks for fungus gnats; timing sweet potato slips to about a month after last frost; container mango culture in 8B/9B; jackfruit from seed in warm zones; cilantro/Brussels sprouts taste genetics; papaya ringspot virus and GMO papayas; corn botany 101; portobello vs. button mushrooms.
