This throwback episode of
The Dirt on Gardening Podcast (Season 1, Episode 32) brings us together—Andre the Farmer, Urban Gardening with Gray, and The Chocolate Botanist—for a fun, wide-ranging conversation that blends real-life gardening with deep dives into
soil fungi, mycorrhizae, and garden biology.
We kick things off with weekend updates—building new metal raised beds, discovering surprise pineapples, and even saving eggshells in Talenti containers—before diving into the fascinating science of
mycorrhizal fungi. We break down what mycorrhizae are, how they help plant roots access water and nutrients, and why adding inoculants can be inconsistent outdoors but more effective in controlled or indoor growing environments.
From there, we explore the wild side of fungi, including
cordyceps (“zombie ant” fungi), mushroom foraging myths, and massive underground fungal networks. We also tackle practical gardening questions like whether mushrooms in your soil are good or bad, and how to think about building healthy, living soil systems.
This episode is packed with practical tips, including:
- Filling multiple raised beds on a budget
- Composting large mulch piles (including palm-based materials)
- Using mushroom compost effectively
- Air layering successes and failures (and why peaches can be tricky)
- Growing pineapples from seed vs. pups
- Choosing asparagus varieties for Zone 8B
- Sourcing and using mushroom spawn
We wrap things up by inviting you to help shape the future of the show—send us your questions, ideas, and topics for our season finale and beyond.
Whether you're into
soil health, fungi, composting, or beginner gardening, this episode mixes science, humor, and hands-on experience to help you grow smarter.
