Healthy trees have strong root systems that keep the tree standing straight up. To support such incredible weight (even small trees may weigh over 1 ton), trees send their roots laterally through the soil, to distribute the tension over a wide area, rather than deep into the soil. This is why tree root health is important – if even a small percentage of the tree’s critical roots become damaged, the entire tree can fall over. If you see damaged roots or the ground starts to lift near the roots, stay clear of the tree and consider it an immediate hazard.
