roots spread beyond drip line

Tree roots quickly spread to outside the edge of the branches. The edge of the branches, commonly referred to as the dripline, is indicated by the dashed line. The black lines are the roots. Roots are commonly found out as far as two to three times the dripline. This means that if the tree crown is 10 feet wide roots can be found out about 20 to 30 feet, sometimes farther.
