Join Dr. Peter Del Tredici as he dives into the world of roots and fungi beneath the soil. How are tree roots structured, and how do they get water and nutrients from the soil into the tree itself? How do symbiotic mycorrhizal fungi promote the growth and survival of both individual plants and entire forests? Understanding the structure and function of a tree's root system will not only help the audience become better gardeners but will enhance their appreciation of how forests work.
