Despite many years of research, these critical organs continue to be poorly understood. A gamut of factors; environmental, cultural, and others, dictate the health of roots and in turn the health of the entire tree. A great deal of literature exists which incorrectly describes root growth. Roots are primarily found in the upper few inches of soil and absorbing roots essential for water and mineral uptake are beyond the dripline.
