Talking Trees

This is your weekly summary of the Talking Trees podcast – exploring everything from microbiomes to medicine. Here's what we uncovered this week:

🌱 Monday 135 - Street Trees and Soil Microbiota
We opened the week underground, exploring how microbial life in the rhizosphere supports urban street trees. Bacteria, fungi, and endophytes form biochemical alliances that boost tree health, immunity, and resilience.

🧷 Tuesday 136 - Groundie
We celebrated the essential role of the ground worker in tree care. Groundies are the backbone of every crew, providing safety, support, and coordination on the ground. Inspired by Jeff Jepson's book, this episode is a tribute to skill and teamwork.

✂️ Wednesday 137 - Lightning and Trees
Midweek struck with energy as we examined lightning's impact on trees. From decay to habitat creation, we discussed how lightning shapes ecosystems and when arborists should install protection systems for vulnerable trees.

📋 Thursday 138 - Trees and Cancer
Could trees help prevent cancer? We explored emerging research linking green spaces to reduced cancer risk, including lower breast cancer rates in urban areas. Though evidence is still evolving, the episode makes a strong case for trees in public health.

✨ Friday 139 - International Society of Arboriculture = ISA
We highlighted ISA's century of dedication to tree care. From launching Arboriculture & Urban Forestry to advancing certification and research, ISA continues to lead global arboriculture into the future.

🐝 Saturday 140 - Trees Pharmacological
We closed the week by stepping into the world of medicinal trees. Discover how ash and white willow produce compounds with anti-inflammatory, antimicrobial, and antioxidant effects – and how sustainable use could shape future medicine.

From microbes to medicine, this week showed how trees touch every layer of life. Keep listening and growing with Talking Trees.
