Ash Dieback: What Should I Do With an Ash Tree in My Garden?

What ash dieback looks like

Typical signs are blackened, wilting leaves in summer, dark diamond-shaped lesions where side shoots meet the stem, thinning in the upper crown and a flush of new shoots lower down as the tree tries to compensate. Decline usually happens over several seasons rather than in one summer, so photographs taken in successive years are genuinely useful.

• Assess the target first: what sits beneath the canopy matters more than the percentage of dieback.
• Declining ash becomes brittle, which changes how safely it can be climbed.
• Secondary decay at the base, often honey fungus, frequently decides the outcome.

Why timing and method change

Healthy ash is climbed and dismantled in the normal way. Advanced dieback can make climbing unsafe, so work may need a mobile platform or a crane, which costs more and needs space. Acting while a declining ash is still structurally sound usually keeps both the method and the price simpler. Cut ash makes excellent firewood once seasoned, so the timber rarely goes to waste.

How James David Forestry Ltd can help

James David Forestry Ltd works across Liverpool, Merseyside, Wirral, Ormskirk and Lancashire. We assess the actual tree, access and surroundings before recommending work. Clear photographs can be useful for initial guidance, but some questions need a site visit and we will not diagnose a dangerous or diseased tree from website information alone.
