Understanding the health of a tree is not always straightforward for homeowners. While some signs of decline, like dead branches or fungal growth, may be visible, a tree’s overall condition often requires professional assessment. Tree surgeons have the expertise and tools to evaluate whether a tree is thriving, under stress, or poses a risk. Their assessment helps determine the best course of action, whether that is pruning, treatment, or safe removal.
The Process of Assessing Tree Health
When tree surgeons evaluate a tree, they take into account both visible and hidden factors that affect its condition. This ensures a complete picture of the tree’s health and stability.
Visual Inspections of the Canopy and Branches
The canopy is one of the clearest indicators of tree health. A professional tree surgeon will look at the overall density, colour, and distribution of the leaves to spot any abnormalities. Sparse foliage, premature leaf drop, or discolouration often signals that the tree is experiencing stress. Branches are also checked for signs of dieback, crossing limbs, or structural weaknesses that could become dangerous over time.
Checking the Trunk and Bark
The trunk acts as the backbone of the tree, so any issues here can be critical. Tree surgeons carefully examine the bark for cracks, splits, or peeling, which may suggest disease or decay beneath the surface. Cavities, hollow sections, or fungal growth around the base are also strong indicators that the tree may be internally compromised. These signs are not always obvious to the untrained eye, making professional expertise essential.
Assessing the Root Zone
Roots are often hidden underground, yet they are the foundation of a tree’s health and stability. Surgeons will inspect the root zone for disturbances such as soil compaction, construction damage, or signs of poor drainage. Even small changes in the surrounding ground can restrict root function, leaving the tree unstable. Exposed or damaged roots above ground are also checked, as these can lead to weakening and a greater risk of collapse in storms.
Using Specialist Tools and Techniques
In some cases, visual checks alone are not enough to fully determine a tree’s condition. Tree surgeons may use diagnostic tools like resistographs, which measure resistance inside the wood to detect hidden decay. Drones or climbing inspections may also be used to get a closer look at the upper canopy. Soil testing, pest identification, and fungal analysis can further provide a more accurate diagnosis, ensuring the right steps are taken for treatment or removal.
Considering Environmental Factors
A tree does not exist in isolation, and the surrounding environment plays a huge role in its health. Tree surgeons assess whether nearby building works, underground utilities, or changes in water levels are impacting the tree. Competition from other trees, over-shading, or nutrient-poor soil may also cause stress. By considering these environmental influences, they can recommend long-term care solutions that not only improve tree health but also ensure safety in the wider landscape.
