For most plants species the radicle dies some time after seed germination, causing the development of a fibrous root system, which lacks a main downward-growing root. Most trees begin life with a taproot, [3] but after one to a few years the main root system changes to a wide-spreading fibrous root system with mainly horizontal-growing surface ...

Rooting Habit, "Tap Root in proportion like a carrot". A seedling tree grows many times in root length to its growth upward in height. The Kentucky coffee tree is not commonly offered in the nursery trade because the taproot makes the tree somewhat difficult to transplant.
