Episode description

Today we invite Dr Elle Barnes back to the show after our very successful conversation after I took Intro to Plant Science with her at NYBG. Elle is a scientist and teacher for NYBG and in addition to Intro to Plant Science, I recently took The Science of Tree Communication class with as well. It was WILD to learn about the underground “wood wide web” that the forest runs on, and how trees communicate with one another through VOCs. I frequently go for morning walks in nearby woods, and since I took that class, I truly look at forest environment differently, and have such a deeper appreciation for it. Plant friends, there is a network of mycorrhizae negotiating transport of vital compounds for trees under every step we take outside! How cool is that?!

In addition to the “Wood Wide Web,” a big part of our conversation in The Science of Tree Communication class was HOW trees and plants communicate with each other through VOCs or Volatile Organic Compounds. Since VOCs are a hot topic in the plant community regarding how “plants clean air”, we took a deep dive to understanding this concept. Get ready to learn all about VOCs, what they are, how they are used and the great “Wood Wide Web”.

Thanks to the NYBG for continuing to create enriching courses that have helped further my Plant Parent Knowledge. Check their offerings out here If you are in the NY area, the NYBG is back open, including the Palm Conservatory and is an absolutely DREAM! Consider becoming a member!
