How far do a tree's roots spread?

For young trees [less than approximately 8 in (20 cm) in diameter], the ratio of root radius to trunk diameter in the documented studies was about 38 to 1. That is to say, a 6 in (15 cm) diameter tree can have a root system that extends nearly 6 m, or 19.7 ft out from the trunk (about 19 ft per 6 in).

Keeping this in view, how far can tree roots spread?

Most tree roots spread 2-3 times the radius of the canopy, and often reach out 5 times the radius of the tree canopy or more in dry conditions. So, for example, if a tree is 6m wide, the radius of the canopy is 3m. The root spread = 2 (to 3) x canopy radius = 2 (to 3) x 3m = 6m (to 9m).
