S6E10: “Mushrooms Aren’t a Death Sentence” — Fungumentals for Arborists Who Diagnose Before They Cut with Kyle McLoughlin of Ironwood Arboricultural

A mushroom on a tree isn’t a verdict — but in arboriculture, it’s often treated like one.

In this episode, Nadina Galle talks with Kyle McLoughlin, a Board Certified Master Arborist and founder of Ironwood Arboricultural, from his two-acre, tree-filled property in St. George, Ontario. Together, they unpack why fungi should be foundational knowledge for anyone caring for trees — and why “there’s a mushroom, cut it down” is more often fear than good practice.

They explore Armillaria and other misunderstood fungi, how decay actually affects tree risk and failure probability, and why arborists should think more like physicians: diagnosing before treating. The conversation also examines how many urban fungal problems are created not by nature, but by how we design, dig, drain, and pave our cities.

Nadina and Kyle discuss the tools that could help shift tree care from reactive removals to proactive preservation — including pneumatic excavation, sonic tomography, and ground-penetrating radar — while returning to a core insight: better growing conditions matter more than any technology.

This episode will resonate with arborists, urban foresters, city managers, and anyone involved in tree risk, urban tree preservation, or the future of urban nature. By the end, you’ll never look at a mushroom on a tree the same way again.
