Palm tree roots grow to be how big?

Answer by  worker3742 (208)

Palm tree roots will generally grow to be about as long as your index finger. This would end up being about 2-3 inches.

Typically the roots will extend approximately 2-3 times from the outside of the tree's dripline. In some cases the root has been known to grow in excess of 10 times the distance from the trunk to the end of the branches.
