Is a Leaning Tree Dangerous in Treasure Valley?
Ideally, trees should grow tall and straight. But what happens when they don’t? In this post, Arbor Safe Tree Service answers the question, “Is a leaning tree dangerous?” As the leading provider of tree services in Treasure Valley, we have the answers to this common question and more.
What Causes a Tree To Lean?
Trees respond to their surroundings. In shaded areas, they often grow toward any available light, leading to a gradual lean. Given that this process happens over time, it’s usually not an issue.
Problems begin, however, when the root system is compromised. Saturated soil can loosen the ground around roots, especially after heavy rains. Erosion has a similar effect, slowly removing the support a tree depends on.
Root damage also plays a role, and you may not even be aware of the issue until a strong storm sends a tree toppling in your yard.
Signs That a Leaning Tree May Be Unsafe
While a leaning tree isn’t always cause for alarm, you’ll want to call for a professional assessment right away if you see any of the following signs:
- Fresh cracks around the base, which could mean the trunk is moving
- Lifting or exposed roots, indicating that the tree is losing its grip
- Splits and cavities or soft spots on the trunk, which point to structural weakness
- Dead branches or thinning leaves, which often indicate disease or decay
Leaning Tree Risk Assessment Tips
You’ll need to examine the tree to see if it poses a real threat. Your first step is to work out how long it has been in its current state. If the specimen has been growing crooked for years, you’re probably in good shape. If it shifts suddenly after a storm, time is of the essence.
In some cases, it may be possible to straighten a leaning tree, but you should consider what happens if it comes down first. Will it damage something or someone on your property or that of a neighbor? If so, it might not be worth saving.
If there’s no immediate danger, watch to see if the lean increases. A stable tree can usually handle a tilt of about 10-15 degrees.
How To Evaluate a Leaning Tree
We recommend that you err on the side of calling a professional for an honest assessment. This not only reduces any risk of the tree falling but also improves the chances of saving it. If your tree is healthy and has a strong trunk, it may be salvageable.
You should always schedule an evaluation for any tree that shows signs of decay, root damage, or rapid movement. The combination of structural weakness and external stress increases the likelihood of failure.
