Typically, a fig tree's root system is content with a soil depth of 1-1.5 meters. The roots of an individual fig tree can stretch several thousand meters in length, surpassing most other tree varieties in this regard. Nevertheless, fig trees, native to South Africa, claim another remarkable distinction: their roots delve deeper into the soil than any other plant.

We often marvel at the tenacity of plants and trees that flourish in the most arid and unforgiving environments. The connection between these plants and the harsh climatic conditions above ground can be puzzling. Yet, these hardy plants continue to thrive. The unforgiving, scorching heat and extended periods without rainfall do not deter their growth. Much of their intricate root systems, which delve deep into the earth, remains concealed from our view.

The fig tree species found in South Africa provides an illustrative example. It thrives on rocky terrain and copes remarkably well with the challenging conditions. While some of its surface roots anchor the tree firmly to the rugged rocks, a single root strand, measuring about ten to twenty centimeters in thickness, burrows deep into the earth, piercing through solid rock. As it navigates through layers of soil and various obstacles, the root continuously seeks out water, instinctively making its way through crevices in the rock and porous strata. At the tip of this root, it secretes a viscous substance that helps dissolve and penetrate layers of earth.

The root's relentless quest for water is driven by the necessity to sustain the fruit-bearing portion of the tree above the ground. Notably, in South Africa, there exists a cave system known as the Echo Caves that provides a clear path of the subterranean journey of these plants. The single root traverses these caves like a water conduit, disappearing into the earth until it ultimately reaches groundwater or another water source. The long journey culminates when water is found.

This particular fig tree boasts a root that reaches an astounding depth of 120 meters, an extraordinary measurement for a tree root. It underscores the tree's enduring struggle for survival and triumph. Equally remarkable is the duration of this journey, as it took an entire seven decades to extend to a record-breaking length of 120 meters in search of a water source. Once the source of water is located, the root transports approximately 25 liters of water daily to the fig tree, defying the relentless heat and aridity of South Africa's dry environment.
