Some pine trees have taproots that grow until the trees reach their mature heights. Longleaf pines develop 10- to 15-foot taproots. Scotch pines, however, may not develop taproots. Their horizontal roots occasionally grow downward to function as taproots. True taproots are more likely on Scotch pines in sandy soils.
