Beneath the forest floor, something extraordinary is happening.
Trees are connected by vast networks of mycorrhizal fungi—fine, threadlike structures that weave through the soil and link roots together. Through these underground connections, fungi help trees access water and nutrients that would otherwise be out of reach. In return, trees provide the fungi with sugars produced through photosynthesis. This quiet partnership is one of nature’s most effective systems for survival.
Research also suggests that these shared networks can sometimes move resources or chemical signals between nearby plants. In certain conditions, trees linked by the same fungi may respond to stress together—such as drought or insect attack—showing that forests function as more than just collections of individual trees.
Some studies have drawn attention to large, well-established trees, often called “mother trees.” These older trees appear to play an outsized role in stabilizing forest networks. There is evidence that they can support surrounding seedlings, especially when those seedlings are struggling. However, scientists continue to debate how much direct resource sharing occurs and how consistent it is across different forests, species, and environments. What is clear is that fungi themselves actively manage these exchanges, and the system is far more complex than a simple act of one tree feeding another.
What these networks reveal, without exaggeration, is this: trees are not isolated organisms. They exist within living systems shaped by cooperation, competition, and constant exchange. The health of a forest depends not on any single tree, but on the relationships that bind them together.
For gardeners—and for communities—there’s a meaningful lesson here. Resilience grows from connection. When we care for soil, support biodiversity, and strengthen the ties within our own ecosystems, we create conditions where life can adapt and endure.
Like a forest, a thriving future depends on balance, cooperation, and care for what comes next.
