Fungi are the forest’s quiet alchemists. They lace the soil with microscopic threads—hyphae—and slip into cracks and pockets where roots can’t quite reach. In doing that, they help trees find what’s hard to come by: water, and nutrients like phosphorus and nitrogen. The tree pays them back in sugars made from sunlight, a simple trade that keeps both alive. And the best part is, those threads don’t always stop at one tree. Mycorrhizal fungi can link roots into common networks, turning the underground into a living weave—one more reminder that a forest is less “every tree for itself” and more a community held together below our feet
