Nature's Stress Manager
Millions of years ago, trees, flowers and grasses faced many natural stresses, such as low soil fertility, drought and temperature extremes. To survive, most plant species established a symbiotic partnership with a unique group of soil organisms called mycorrhizal fungi. These fungi are considered by plant scientists to be the biological cornerstone of plant life on earth.

This little known family of beneficial fungi live in and around the roots of 95% of the earth's plant species, serving as a secondary root system, extending themselves far out into the soil. Mycorrhizae extract mineral elements and water from soil for their host plant, and live off the plant's sugars. Trees and plants with thriving "mycorrhizal roots" systems are better able to survive and thrive in stressful man made environments.
