Trees add structure, privacy, and character to a property, but there are times when a tree can become a genuine safety concern. The challenge for many homeowners is knowing when a tree has crossed the line from manageable to unsafe. Recognising the warning signs early allows for informed decisions that protect people, property, and the surrounding landscape.
At Burwell Tree Surgeons, we work with property owners across Burwell to assess tree safety and recommend appropriate action based on professional judgement rather than guesswork.
Visible Structural Changes in the Tree
One of the clearest indicators that a tree may be unsafe is a noticeable change in its structure. Leaning trunks, particularly those that have shifted suddenly, can suggest root instability. Cracks running vertically along the trunk or major limbs may indicate internal failure, even if the tree still appears alive.
Trees are designed to distribute weight evenly. When that balance changes, the risk of collapse increases.
Signs of Decay or Hollowing
Decay is not always obvious from the outside. However, certain signs strongly suggest internal deterioration:
- Cavities or hollow sounds when the trunk is gently tapped
- Fungal growths at the base or along the stem
- Soft or crumbly wood around old wounds
Internal decay weakens the tree’s core strength, making it far more likely to fail under normal weather conditions.
Root Plate and Ground Movement
A tree’s stability relies heavily on its root system. Raised soil, cracking ground, or exposed roots near the base can indicate root plate movement. This is particularly concerning if it appears after heavy rain or wind.
When roots lose their anchoring ability, the entire tree can become unpredictable, even if the upper growth still looks healthy.
Dead or Dying Branches in the Upper Canopy
While occasional deadwood is normal, widespread dieback in the crown can signal serious stress or disease. Large dead branches increase the risk of sudden breakage and falling debris.
If dead growth is concentrated on one side of the tree, it may also indicate uneven loading and structural weakness.
Repeated Storm Damage or Limb Failure
A tree that regularly loses branches during moderate weather may no longer be structurally sound. Repeated failures suggest that the tree is struggling to cope with environmental pressures and may not be suitable to retain in its current condition.
This is especially important for trees close to homes, footpaths, or neighbouring properties.
Changes in Growth or Seasonal Behaviour
Trees that leaf later than others, drop foliage early, or show sparse growth may be experiencing internal decline. While poor growth alone does not automatically mean a tree is unsafe, combined with other symptoms it can indicate a deeper problem.
Professional assessment helps distinguish between temporary stress and long-term instability.
Why Professional Assessment Matters
Determining whether a tree is unsafe requires experience and technical understanding. Many serious defects develop internally and cannot be diagnosed through visual inspection alone.
A qualified tree surgeon can evaluate structural integrity, root stability, and overall health before advising whether remedial work can resolve the issue or whether removal is the safest option.
Conclusion
An unsafe tree rarely fails without warning. Leaning trunks, decay, root movement, and repeated limb loss are all signs that a tree may no longer be safe to retain. Acting early helps prevent unexpected damage and allows for planned, responsible tree management.
