Question

How deep is the root system of a giant sequoia?​

Answer 1

4 meters (13 feet)

The sequoias root system is wide spreading, but shallow. There is no taproot. A mature sequoia's roots can occupy over 1 acre of earth and contain over 90,000 cubic feet of soil.

Answer 2

There is no taproot. They only root to 12 to 14 feet deep even at maturity. A mature sequoia's roots can occupy over 1 acre of earth and contain over 90,000 cubic feet of soil. That mass of matted roots and soil has to maintain the equilibrium of a tree that is nearly 300 feet tall and weighs nearly 2 million pounds.
