Which trees roots grow straight down?

Taproots are large roots that grow straight down below the trunk of the tree. Compacted soil makes it difficult for trees to develop such a root. Most trees will never establish a taproot, but instead grow a sprawling network of woody and feeder roots, usually no deeper than 12 to 24 inches.

Which trees have the deepest roots?

Shepherd’s tree (Boscia albitrunca), native to the Kalahari Desert, has the deepest documented roots: more than 70 meters, or 230 feet, deep. Their depth was discovered accidentally by drillers of groundwater wells.

Is it OK to cut through tree roots?
