5 Warning Signs that a Tree Is at Increased Risk of Falling

Trees can pose serious safety risks if they become unstable. A tree that is structurally compromised may fall without warning, potentially causing injury or significant damage to property. Recognizing the warning signs early can give you the opportunity to take preventive action. At Tree Experts, our local arborists are highly experienced with tree removal in the greater Tucson area. Here are five warning signs that a tree may be in danger of falling over suddenly.
Leaning Dramatically
A noticeable lean, especially one that has worsened over time, is a major red flag. While some trees naturally grow at an angle, a sudden or increasing lean can indicate root damage or soil instability. If a tree appears to be tilting more each month, it’s likely struggling to stay upright and should be evaluated by an arborist as soon as possible.
Cracked or Uplifted Soil Around the Base
One of the often overlooked signs of a tree at risk is disturbed soil near the trunk. If you notice cracked or mounded soil on one side of the base, the tree may be beginning to uproot. This is often a sign that the roots are no longer anchored firmly in the ground. In these cases, a fall could be imminent.
Large Cracks in the Trunk
Deep vertical cracks or splits in the trunk can weaken the structural integrity of a tree. Such cracks often develop from internal decay, storm damage, or sudden changes in weight distribution. A compromised trunk can make a tree more susceptible to snapping or falling, especially during extreme weather conditions.
Extensive Root Damage
Roots are critical for stability. If a tree has lost a significant number of surface roots due to construction, soil erosion, or disease, it may no longer have the support needed to remain upright. Fungal growth at the base can indicate that the root system is failing, which greatly increases the risk of sudden toppling.
Hollow or Decayed Interior
A tree can look relatively healthy on the outside while rotting from the inside. Hollow trunks or large cavities are clear signs that the internal structure has been compromised. Trees with major internal decay are more likely to fall with little to no warning.
