Trees bring character, shade and natural beauty to gardens and outdoor spaces, but they can sometimes develop problems that affect their stability and safety. Disease, decay, storm damage and structural weaknesses can all increase the risk of falling branches or, in more serious cases, a tree failing entirely.
For property owners in Godalming, Surrey, recognising the warning signs of an unsafe tree is an important part of responsible tree care. While not every damaged or leaning tree needs to be removed, understanding when professional attention is required can help prevent potential harm to people, buildings and surrounding areas.
1. Dead or Falling Branches
Dead branches are one of the most noticeable warning signs that a tree may need attention. They can become brittle over time and may break away during strong winds or heavy rainfall.
Look out for branches with no leaves during the growing season, brittle wood, missing bark or sections that appear dry and lifeless. Large dead limbs above paths, driveways, seating areas or buildings deserve particular attention.
Professional tree surgery can involve removing dead or damaged branches while retaining the healthy structure of the tree wherever possible. This helps reduce the risk of falling timber and supports better ongoing tree management.
2. Cracks in the Trunk or Main Branches
Significant cracks or splits in a tree’s trunk can indicate structural weakness. These may develop following storm damage, heavy branch loading, previous pruning or internal deterioration.
Pay particular attention to cracks that extend deep into the trunk, areas where the wood appears to be separating and large splits where major branches join the main stem.
Not all surface cracks mean a tree is about to fail, but substantial or widening splits should be assessed by a qualified tree surgeon. The location, depth and extent of the damage all influence how serious the problem may be.
3. Fungal Growth and Signs of Decay
Fungal growth around the base of a tree, on the trunk or near major roots can sometimes indicate internal decay. Certain fungi break down wood, potentially reducing the strength of the trunk or root system.
Other warning signs include soft or hollow-sounding sections, cavities, damaged bark and areas where the timber appears to be breaking down.
It is important to understand that visible fungal growth does not automatically mean a tree is unsafe. Different fungi affect trees in different ways, and a professional assessment is needed to establish whether structural strength has been compromised.
4. Sudden Leaning or Changes in Position
Some trees naturally grow at an angle, so a leaning trunk is not always a cause for concern. However, a tree that begins leaning suddenly or appears to have shifted position may have a problem with its root system or stability.
Look for signs such as:
- Cracked or raised soil around the base.
- Exposed or damaged roots.
- A noticeable change in the tree’s angle.
- Movement of the root plate.
- Fresh cracks in the surrounding ground.
These symptoms may indicate that the tree has become unstable, particularly after periods of strong wind or heavy rain. If a tree appears to be moving at its base, keep people away from the area and arrange a professional assessment promptly.
5. Damaged or Weak Root Systems
Roots provide the support a tree needs to remain upright while also absorbing water and nutrients. Damage caused by excavation, construction activity, soil compaction or decay can affect the tree’s ability to remain stable.
Although much of a root system is hidden underground, visible warning signs may include exposed roots, fungal growth near the base, soil movement and changes in the condition of the canopy.
Avoid cutting or disturbing large roots without professional advice. Unnecessary root damage can weaken the tree further and may increase the risk of instability.
6. Unbalanced or Overextended Canopies
A tree with an excessively heavy or uneven canopy may experience additional strain, particularly where large branches extend in one direction or have weak attachment points.
This can happen naturally as a tree grows towards available light, but previous unsuitable pruning can also encourage poorly balanced regrowth.
Crown reduction or selective pruning may help manage the size and shape of the canopy where appropriate. However, excessive cutting can cause further stress and should be avoided. A tree surgeon can assess the structure and recommend work that supports the tree’s long-term condition.
7. Storm Damage and Broken Limbs
Strong winds and severe weather can leave trees with split branches, damaged trunks and partially detached limbs. Some damage is immediately visible, while other defects may remain hidden until the affected branch moves or breaks.
After a storm, check trees from a safe distance for hanging branches, fresh cracks, exposed roots and changes in their position. Never attempt to remove large or unstable branches yourself, as they can fall unpredictably.
Professional tree surgery can address storm damage through controlled pruning, removal of hazardous limbs or, where necessary, complete tree removal.
When Should You Contact a Professional Tree Surgeon?
A tree should be assessed when there are signs of significant structural damage, decay, root movement or sudden changes in its condition. An experienced tree surgeon can examine the trunk, branches, canopy and surrounding ground to determine the level of risk.
Not every problem requires removal. In many cases, appropriate pruning, deadwood removal or ongoing monitoring can help retain the tree while addressing specific concerns.
For property owners in Godalming, Surrey, arranging professional attention when warning signs first appear can help prevent minor defects from developing into more serious safety issues.
Conclusion
Dead branches, trunk cracks, fungal growth, sudden leaning, root damage and storm-related defects can all indicate that a tree may be unsafe. Recognising these warning signs early is essential for protecting people and property while preserving healthy trees wherever possible.
