Check your trees for warning signs
Walk around your San Diego trees from the ground. Look at the canopy, trunk, and soil. Take photos of what you notice. A thin crown or a single hole does not mean the tree will fall. If the lean shifted or a branch looks loose, keep everyone away. Then reach out to a licensed independent tree crew.
What you'll learn
- Checking bark, roots, and overhead limbs from below without ever leaving the ground
- Reasons one sparse top, dark spot, cavity, or tilt won't guarantee a falling trunk
- How D-shaped holes on oaks are different from general thinning or bark stains
- When a shifted lean, heaving soil, or loose limb means you should call a licensed crew
Step by step
- Begin your visual check far enough back from the base. Look for splits, hollows, and fungal growths. Take pictures of what you see. Never poke at wood or scale the tree yourself.
- Step back and look up at the canopy. Thinning, dead tips, or early leaf drop are hints, not proof of failure.
- Look at the soil near the root flare for fresh mounds or cracks. That could mean the roots are shifting. Keep people away from under the tree if you spot it.
- On oaks, D-shaped exit holes point to goldspotted oak borer activity that a diagnostician should review. Crown thinning or bark staining by itself is not a diagnosis.
- Keep a dated photo record. If a lean has shifted, soil has pushed up, or a limb seems loose, keep people clear. Then contact a licensed independent tree crew.
Safety note
An old lean might be fine. Fresh soil heave or a sudden angle shift is another story. Keep everyone away from under that tree. Call 911 if someone is in danger right now. For a professional opinion, Limb SD connects you with licensed independent tree crews.
