Perennials Enrich Soil


Perennials have very deep, widespread root systems. The roots plow soil as they grow, creating an aggregate structure where soil granules clump together, leaving spaces where oxygen and water can collect. Fungi and microbes that contribute to soil aggregation are carried through the soil by the plant roots and activated by the oxygen and water present there, creating a delicate ecosystem balance. Perennial root growth helps soil retain water, collect nutrients, and also helps prevent weed growth.
