Fast growing oak trees can easily grow 2 to 3 feet per year when they are young.The roots of mature oaks grow predominantly within the upper three feet of soil. Most of the roots responsible for the uptake of water and minerals are concentrated within 18 inches of the surface. Few roots grow deeper than three feet.Natural oak seedlings appear to grow best in partial shade. Soil under mature trees also contains mycorrhizae, soil-borne fungi that grow on the roots of trees, increasing their ability to absorb water and nutrients.
