Tree roots serve a variety of functions for the tree. They absorb and transfer moisture and minerals as well as provide support. Studies have shown root spread to be 4 to 7 times the dripline distance (radius) of the tree. Roots require water, oxygen, minerals, and warmth, which are usually found in the upper few feet of soil, so the major portion of a tree’s root system is in the top few inches of soil.
