Early tree disease diagnosis is essential to protect trees and prevent long-term damage.
Pests and diseases are increasingly affecting common tree species across the UK. As a result, early identification allows you to take action before problems worsen or spread to nearby trees.
At Venners Arboriculture, we provide accurate assessments to identify disease, decay, and structural weakness.
Signs Your Tree May Be at Risk
You may need a professional assessment if you notice:
- Deadwood or dying branches
- Fungal growth on the trunk or roots
- Cracks, cavities, or decay
- Leaf discolouration or early leaf drop
- General decline in health
In these situations, acting early helps reduce risk and avoid costly remedial work later.
Advanced Tree Decay Testing
Where visible signs suggest internal decay, we can arrange for detailed testing to assess the structural integrity of the tree.
We use specialist equipment, including:
- Picus Sonic Tomograph for non-invasive decay detection
- Resistograph F300E to measure internal wood density
These tools allow us to identify hidden decay and provide clear, evidence-based recommendations.
Laboratory Testing and Disease Identification
In addition to on-site assessments, we can collect samples of diseased tissue for laboratory analysis.
This process provides:
- Accurate identification of pests or pathogens
- Confirmation of suspected diseases
- Clear recommendations for treatment or management
As a result, you receive a reliable diagnosis that supports effective decision-making.
Rapid On-Site Diagnosis
Where appropriate, we also use portable diagnostic testing equipment on site.
This allows us to:
- Identify common diseases quickly
- Provide immediate insight into tree health
- Recommend next steps without delay
Therefore, you can act quickly to manage risks and protect surrounding trees.
Practical Advice to Protect Your Trees
Following diagnosis, we provide clear and practical recommendations to help you:
- Manage or remove infected trees safely
- Prevent the spread of pests and diseases
- Maintain the long-term health of your trees
- Reduce safety risks from structural weakness
Because every site is different, we tailor our advice to your specific trees and environment.
