Why Is My Tree Leaning? When to Worry and What to Do

Writer's picture: Aaron CullAaron Cull

Ever noticed a tree in your yard tilting to one side? Maybe it’s always been that way, or maybe the lean seems to be getting worse. Either way, a leaning tree is not something to ignore. In Calgary, where strong winds, tough winters, and unpredictable weather can stress trees out, a lean could mean trouble.


So, is your leaning tree just doing its thing, or is it a ticking time bomb? Let’s break it down. And if you need expert advice, Evergreen LTD is here to help.


Why Trees Lean in Calgary

Trees don’t just lean for fun—there’s usually a reason. In Calgary, the most common culprits are:

  1. Strong Winds (Especially Chinooks!)

    If you’ve lived in Calgary for a while, you know the wind here isn’t messing around. Chinook winds can hit over 100 km/h, which can push young trees off balance or worsen an existing lean. Trees with shallow roots or uneven canopies are especially at risk.

    Poor Soil and Drainage

    A lot of Calgary’s soil is heavy in clay, which shrinks when dry and expands when wet. This constant movement can shift a tree’s roots, causing it to tilt. If your yard has drainage issues, pooling water can weaken the soil around the roots, making things even worse.

  2. Root Damage from Construction

    Ever had landscaping done, a sidewalk put in, or a new fence installed? Heavy equipment and digging can damage or cut tree roots, leaving the tree without the support it needs. If the damage is bad enough, the tree may start to lean—or worse, fall.

  3. Snow and Ice Load

    Calgary’s winters aren’t just cold—they’re heavy. Snow and ice can weigh down one side of a tree, making it bend under the pressure. While some trees bounce back in the spring, others get stuck in a permanent lean.

  4. Trees Growing Toward Light

    Some trees naturally lean as they stretch toward the sun. This happens a lot in backyards where trees are planted near houses or fences. It’s usually harmless, but if the lean keeps getting worse, it might be time to take a closer look.


Should You Be Worried About a Leaning Tree?

Not all leaning trees are dangerous, but some are just waiting for the right storm to come crashing down. Here’s when to worry:

  • The Lean Is Getting Worse

    If your tree is tilting more than before, it’s a sign that something underground (like the roots) is failing.

  • The Roots Are Lifting or Cracked

    Look at the base of the tree. Are the roots lifting out of the ground? Is the soil cracked or uneven? That’s a major red flag. The Tree Is Leaning Over Your House, Car, or Sidewalk

    A tree leaning over a structure, driveway, or pedestrian path is a lawsuit waiting to happen. If it falls, you could be on the hook for damages.

  • The Tree Moves in the Wind

    Some movement in the wind is normal. But if your tree sways a lot or shifts at the base, it’s not stable.

  • It’s a Large, Mature Tree

    A small tree leaning? Maybe fixable. A huge, heavy tree leaning? That’s a serious hazard. Mature trees carry tons of weight, and when they go down, they take a lot with them.


Your Options: Ignore, DIY, or Call a Pro?

Okay, you’ve got a leaning tree. Now what? Here are your options:

  • Ignore It (Not Recommended)

    Hope is not a strategy. A bad lean doesn’t just fix itself. If a tree is unstable, it’s only a matter of time before gravity wins.

  • Try to Fix It Yourself (Risky)

    Some people try to brace, cable, or stake a leaning tree. That works for small, young trees but isn’t a long-term solution for bigger ones. And let’s be honest—if you’re Googling this, you probably don’t have the gear or training to do it safely.
