CHARACTERISTICS OF THE ROOTS OF AN OLIVE TREE
Olive trees take root easily. Their comfort zone consists of soil that drains well (no puddles) and allows the roots to spread out, occupying an area below the ground as wide as the canopy. The roots need space to grow downward (over four feet), with plenty of air to allow the roots to spread out without constraints.
The root system branches out in such a way that in times of water shortage the roots seek out the nutrients it needs to survive. That is why an olive tree has so many different roots.
