Quick Summary
Changes to look for in an ash tree, what affects retention decisions and why declining ash needs a planned method of work.
A thinning ash canopy, dead branches or changes around the base are reasons to arrange an assessment. Record when you noticed them and what lies beneath the tree. A roadside ash and one in an unused corner of a field need different management decisions.
Symptoms are a starting point
Ash dieback can cause leaf loss, dead branches and lesions. Other problems can also affect an ash, so visible decline needs assessment rather than a diagnosis based only on a photograph. Keep photographs from previous growing seasons if available; they can help show a change in condition.
Retention may be possible
The Forestry Commission advises retaining healthier ash where safe, because some may have tolerance to the disease. It does not recommend treating every infected tree as an automatic removal. See its ash dieback management guidance.
The assessment needs to consider structural condition, the extent of decline and the use of the surrounding space. Ask what monitoring would involve if retention is proposed, including what changes should prompt another visit.
Work on declining ash needs planning
Brittle timber can affect whether a tree can be climbed and how it can be dismantled. Machinery access, nearby roads and buildings can therefore change the method and price. Explain access constraints before arranging ash dieback work.
Disease does not remove the need to check tree protection and any felling requirements. The applicable checks depend on the site and proposed work. Keep the relevant correspondence with the quote.
Plan the space after removal
If removal is recommended, specify whether the stump is included, what timber remains and what clearance is required. Removing a boundary tree may expose a fence or hedge needing separate attention. Those should be quoted as defined tasks rather than assumed additions.
For an ash in Surrey, send Brad the location, photographs taken safely and a description of the changes. Call about new splits, unstable branches or blocked access rather than waiting for a routine online enquiry.
What Ash Dieback Means For Your Tree
Include changes in the canopy, trunk or surrounding ground, and say what is beneath the tree. An assessment can establish the appropriate next step.
When To Pick Up The Phone
- When an ash tree is losing crown or dropping small branches
- When you are not sure whether the tree can stay or needs to come down
- When you want an honest assessment rather than a worst-case quote
