How Deep Is The Root Ball?
I want to replace some arborvitaes with a smaller variety. To do so, I have to saw them down and dig up the stumps. The arborvitaes are more than 20 years old, about 11 1/2 feet high, and about 4 1/2 feet in diameter. Can you estimate how many feet below the surface of the ground the root ball will extend?
Here is some general information. The majority of tree roots are located in the upper 12 to 18 inches of soil. The roots can extend about 2-3 times beyond the "dripline" of the tree.
