Question

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

Answer 1

Answer:

12 to 14 feet deep

The sequoias have a matting, shallow, and wide spreading root system. 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.
