Trees are often seen as resilient, long-lasting features of our landscapes. However, even the strongest trees can develop health issues that, if left untreated, may lead to safety hazards or the eventual loss of the tree. While some signs of distress are easy to spot, others may go unnoticed without a professional assessment.
In this guide, we’ll walk you through the key indicators that suggest your tree might need a professional health assessment.
By knowing when to call in an expert, you can ensure your trees remain healthy and safe, protecting both your property and the surrounding environment.
Why Tree Health Matters
Healthy trees are not only beautiful but also contribute to the local ecosystem. They provide shade, improve air quality, and serve as habitats for wildlife.
On the other hand, a sick or dying tree can become a liability, potentially damaging property or posing safety risks to people nearby.
Regular assessments help catch problems early, allowing for intervention before the damage becomes too severe.
Key Signs Your Tree Needs a Professional Health Assessment
Not all tree issues are immediately visible. Some problems develop slowly over time, while others can be triggered by external factors such as weather or disease. Below are some of the most common signs that indicate it’s time to seek professional advice.
1. Dead or Dying Branches
One of the clearest signs your tree may be in trouble is dead or dying branches. These branches often lack leaves, appear brittle, and can break off easily. If you notice multiple dead branches, it could indicate that the tree is struggling with disease, pests, or internal decay.
Why Dead Branches Matter
Dead branches can pose a safety hazard, especially in high winds or during storms. If left unaddressed, they can fall and cause damage to property or injure someone. A professional tree surgeon can safely remove dead branches and assess the overall health of the tree.
2. Cracks or Splits in the Trunk
Cracks or splits in the trunk of your tree are another clear indicator of underlying health issues. These may be caused by frost cracks, weather stress, or even disease. Deep cracks can compromise the structural integrity of the tree, making it more likely to fall in bad weather.
What to Look For
Check the trunk regularly for visible splits or cracks. While small cracks may not always be a cause for concern, larger or deep cracks can weaken the tree significantly. A professional can assess whether the tree can recover or if further action is needed.
3. Discoloured or Wilting Leaves
The appearance of your tree’s leaves is one of the best indicators of its overall health. If you notice that leaves are discoloured, wilting, or dropping prematurely, it could be a sign of disease or nutrient deficiency.
Common Leaf Issues:
- Yellowing leaves: Often a sign of overwatering, poor drainage, or nutrient deficiencies.
- Brown or black spots on leaves: These can indicate fungal infections or insect infestations.
- Wilted leaves: Trees that appear wilted, even after being watered, may be suffering from root issues or vascular diseases.
If these symptoms persist, it’s best to consult a tree expert, such as Tree Surgeons Middlesbrough, who can diagnose the problem and recommend appropriate treatments.
4. Fungus or Mushrooms Growing on the Tree
While mushrooms in your garden may not always be a bad sign, when they appear directly on the tree’s trunk or around its base, they usually indicate internal decay. Fungal growth suggests that the tree’s wood is decomposing from the inside, which weakens its structure over time.
What to Look For:
- Mushrooms at the base of the tree: These are often signs of root rot, a serious condition that can destabilise the tree.
- Fungal growth on the trunk: White, brown, or orange growths on the bark often point to internal decay or disease.
If you notice any of these signs, it’s essential to get a professional assessment. Once internal decay sets in, the tree may become unstable and require removal to prevent it from falling unexpectedly.
5. Leaning or Unstable Trees
A leaning tree is a serious warning sign, especially if it has developed a sudden tilt. Trees that lean naturally can still be stable, but if your tree begins to lean more than usual or shifts unexpectedly, it’s time to seek professional advice.
Causes of Leaning Trees:
- Root damage: If the roots have been compromised by flooding, construction, or disease, they may no longer support the tree effectively.
- Soil erosion: In areas with heavy rainfall or poor drainage, the soil around the roots may erode, causing the tree to lean.
- Wind damage: High winds can force trees to tilt, especially if they are already weakened.
A leaning tree poses a significant safety risk, and an arborist can determine whether it can be saved or if removal is the safest option.
6. Exposed or Damaged Roots
The health of a tree’s roots is crucial for its overall stability and vitality. If you notice exposed roots, either due to erosion or landscaping, it can lead to problems like root rot or structural instability. Similarly, roots that are damaged by construction or digging can affect the tree’s ability to absorb nutrients and water.
Signs of Root Problems:
- Exposed roots: Roots that are visible above ground or that appear cracked or broken can indicate poor health.
- Root rot: This can be harder to spot but may show up as soft, mushy roots or fungal growth at the base of the tree.
A professional tree surgeon can assess root health and recommend solutions such as improving soil conditions or installing support systems to stabilise the tree.
7. Pests and Insects
Insects and pests can cause significant damage to trees, often acting as carriers of disease. If you notice an increase in insect activity around your tree, such as beetles, caterpillars, or aphids, it’s essential to take action.
Signs of Pest Infestation:
- Holes in the bark: Small holes can indicate the presence of boring insects that are feeding on the tree’s internal structure.
- Chewed leaves: This may suggest caterpillars or other leaf-eating insects are present.
- Sticky residue on leaves: Aphids and other pests often leave behind a sticky substance, known as honeydew, which can attract further problems like mould.
An expert tree surgeon can identify the specific pest and offer treatment options to manage the infestation and prevent further damage.
8. Unusual Bark Texture or Colour
Healthy bark should be consistent in texture and colour. If you notice peeling, cracked, or discoloured bark, it could be a sign that the tree is struggling with disease or environmental stress.
What to Look For:
- Peeling bark: This can occur naturally in some tree species, but in others, it may indicate a problem, such as insect infestation or fungal growth.
- Sunken or discoloured areas: These can point to issues such as disease or decay beneath the surface.
If you observe any changes in the tree’s bark, it’s worth getting a professional assessment to determine the cause.
