Listen in as we talk about a niche and noble hobby: tree collecting. Author Amy Stewart joins us to discuss her newest book, The Tree Collectors: Tales of Arboreal Obsession, which profiles 50 different tree aficionados ranging from scientists cataloging rare species, to families preserving their heritage, and conservationists fighting to reforest their land. Their stories shed light on both the cultural and environmental necessity of trees—and how climate change, policy shifts, and financial barriers are all hindering their protection. Stick around for insights into the ways these collectors are benefiting biodiversity, and what roles you can play in the effort.

In this week’s episode, we’re joined by NYBG Assistant Curator Ana María Bedoya, Ph.D., whose career as a scientist takes her on many a wild adventure. She spends much of her time tracking down aquatic plants that live in some of the harshest conditions, including steep cliffs, river rapids, and tumbling waterfalls—a practice Bedoya likes to call “extreme botany.” Listen in as we discuss her research in the wilderness of South America, the reasons many aquatic plants are especially vulnerable to climate change, and her journeys getting her feet wet (literally) in Earth’s most extreme ecosystems.

In this week’s episode, we discuss the future of horticulture—and the simple, sustainable changes that can help the planet heal. Come join Chad Massura, founder of Rosy Soil, and Kurt Morrell, VP of Horticulture Operations at NYBG, for a chat about the importance of peat-free soil for a carbon-neutral world. Massura shares the story behind potting products like his that move beyond the extractive model of the peat industry, while Morrell elaborates on eco-friendly practices in horticulture. You’ll leave the conversation with a new tactic in hand to make your own garden greener!
