How ArborSafe Evaluates a Leaning Tree: When Lean Is a Hazard and When It's Just the Way the Tree Grew

Post Copy

A leaning tree doesn't automatically mean a dangerous tree. But it does mean a tree that deserves a trained eye, because the difference between a tree that has always grown at an angle and a tree that is actively moving matters a great deal for what you do next.

When our arborists evaluate a leaning tree, we're looking at several things at once. The root plate is one of the first: is the soil mounded or cracked on the tension side? Has the tree recently shifted, or has it held this angle for years without change? We also look at the lean relative to the species, since some trees, like willows or certain ornamentals, grow asymmetrically as a normal part of their development. The trunk's taper and the direction of the lean relative to targets like buildings, driveways, and power lines factor into how urgently we recommend action.

A tree with a lifelong lean and a stable root system may need nothing more than monitoring. A tree that has recently developed a lean after a storm, soil disturbance, or root damage is a different situation entirely. Our job is to read the tree accurately and give you an honest assessment, not to push toward removal when other options exist.

Have you ever had a tree on your property that concerned you because of how it was growing? We'd be curious what prompted you to take a second look at it.
