Does My Tree Need to Be Removed? 8 Warning Signs
Quick answer: A tree may need removal if it is dead or mostly dead, has a large split or cavity in the trunk, has started leaning suddenly, or has damaged roots. Many other problems, such as a few dead limbs, a heavy limb over the roof or a weak fork, can be fixed with pruning or cabling. When in doubt, get a professional to look before deciding.
8 warning signs
- No leaves in the growing season, or leaves only on a few branches.
- Large dead limbs in the upper crown (dieback).
- A new or worsening lean, especially with cracked or heaving soil at the base.
- A split trunk or a crack running through a main fork.
- Cavities or soft, crumbly wood in the trunk.
- Mushrooms or shelf-like conks at the base or on the trunk, which can signal internal decay.
- Root damage from construction, trenching or a heavily compacted root zone.
- Growth into a structure or over the roof, where a failure would do serious damage.
One sign on its own doesn't always mean removal, but several together are serious.
