After a storm, it can be a jarring sight to step outside and see one of your favorite trees with a list. How far can a tree lean before it falls? You probably should worry about the tree’s stability and consider tree removal if it leans 15 degrees or more from vertical.
However, every tree and species is different, meaning consulting with a trusted local arborist is the best choice. Learn what goes into a leaning tree assessment from a professional.
Situations That Cause a Tree To Lean
Several factors can cause a tree to develop a sudden lean or to grow at an odd angle from the time it sprouted.
Environmental Factors or Physical Damage
If you notice a new problem with trees leaning after storms, they probably suffered some sort of damage in the storm. If the tree had an unknown structural integrity problem before the storm, the rough weather may have worsened it, causing the new lean.
Trees use their flexible branches to create natural wind resistance. However, powerful winds in a storm can cause limb and trunk cracks if the tree can’t flex enough to resist the wind’s force.
If someone hits a tree with a car or damages the roots while digging a trench, the plant may suddenly develop a lean.
Root System Problems
When the tree’s root structure has damage or is rotting, you probably won’t notice because you can’t see the roots underground. The first sign of this issue for most people is a leaning tree. How far can a tree lean before it falls when it has root damage? Any tree with root weakness that’s leaning more than 15 degrees from vertical is in danger of falling to the ground.
Trunk Deformity or Damage
When the tree’s trunk develops a cavity, the plant may start to lean. Trunks have no flexibility compared to the natural flex found in the upper branches. If the tree starts leaning after the cavity in the trunk appears, this usually indicates that the trunk’s damage may soon cause the tree to fall.
Natural Growth Patterns
Some trees simply grow with a lean, and it doesn’t affect the plant’s integrity. If the tree struggled to reach sunlight when it was young because of nearby large trees, it may cause a lean in the trunk. Some species of trees naturally grow with a lean, even when the root structure is strong.
When a Leaning Tree Is Worrisome
Perhaps you have an older tree on your property that always had a lean, but it now leans a little more than it did last month. A tree where the lean slowly becomes worse should concern you. Arborists can determine the reason for the lean and attempt to remedy it to save the tree.
An unstable tree is especially worrisome when it is leaning toward a home, garage, or play area. These leaning trees need regular inspections from a professional, even if you don’t notice the angle of the lean changing.
If the leaning tree is in a remote area and poses no threat to property or someone’s health, it probably doesn’t need regular inspections.
Options for Remedying a Tree That Is Leaning
When you have a leaning tree, you have a few options for handling it. How far can a tree lean before it falls, and should you cut it down before it can fall? If it is near your house or could injure someone if it falls, professionals will recommend cutting it down before it can fall.
Depending on the cause and angle of the lean, arborists may be able to try to straighten it. They can use braces and cables to support the weight of the tree until the roots grow strong enough to support a vertical orientation. Such techniques work better for smaller, younger trees than large, mature trees.
