EP #69 - Guardians of the Green: Trees talk to each other, and Josh Fritz listens to their stories.

Master arborist Josh Fritz has spent 28 years uncovering the hidden wonders of tree preservation, from the underground fungal networks that allow trees to communicate to the historical significance of Boston’s oldest trees. His journey into arboriculture was inspired by his great-uncle, a tree surgeon who encouraged him to pursue work that was both meaningful and enjoyable. Though a water skiing accident prevented Fritz from climbing, it led him to a leadership role at Hartney Greymont Davey Tree Expert Company, where he now spearheads preservation efforts as a dedicated "tree doctor."

Beyond science, Fritz understands the deep emotional bonds people share with trees, whether it's a backyard sapling planted by a child or a centuries-old landmark shaping history. He tackles climate-related shifts, such as sugar maples retreating northward, and diagnoses diseases threatening beloved trees. His team’s work ensures that trees—and the stories they hold—remain protected for generations. Interested in safeguarding your own living landmarks? Visit www.hartney.com to learn more.
