Pecan trees are long-living, deep-rooted giants of the orchard. Their success doesn’t depend only on sunshine, water, and fertilizer—it also relies on an underground community of tiny, invisible partners: microbes. These partners include fungi and bacteria that live in and around the tree’s roots (the “rhizosphere”), helping pecans absorb nutrients and water, withstand stress, and...
