Pine tree roots are the underground woody growths of a pine tree that anchor it to the ground and take up nutrients and water from the soil. Pines are characterized by a preference for sandy and loamy soils, and their roots are adapted for this.
Pines generally have broad, shallow root systems. They sometimes have deep taproots that help anchor them. Taproots are tapered roots that grow directly from the main trunk and generally have less girth than the trunk itself, though in certain pines such as the Longleaf, they can be quite thick. The other roots extend themselves from the taproot out into the surrounding area. These secondary roots rarely extend deeper than 3 feet into the soil. In sandy soil, these roots may go deeper, because sand is packed looser and water drains more quickly from the soil. This necessitates having a more extensive network of roots to take up any water available.
