Understanding Ash Dieback
Ash dieback is a serious fungal disease that has spread across the UK and is now affecting ash trees throughout Hertfordshire, including Welwyn Garden City.
It gradually weakens the tree by reducing its ability to transport water and nutrients. Over several years, this can cause the tree to decline and eventually become unsafe.
For homeowners and businesses with ash trees, spotting the signs early and seeking professional advice is key. With many trees in the area protected under local regulations, knowing the right steps to take is even more important.
Spotting the Signs on Your Property
Early symptoms of ash dieback include:
Brown or wilted leaves during summer
Diamond-shaped dark patches on bark and shoots
Dead branches appearing at the top of the tree
New shoots sprouting directly from the trunk
Leaves falling earlier than normal in late summer
Later-stage symptoms include:
Large sections of the tree dying back
Spreading dark patches on the trunk
The tree leaning or looking unstable
Secondary problems such as insects or fungi taking hold


If you have noticed any of these signs, call Evoke Tree Services on 01707 708202 for professional guidance.
Professional Tree Assessments
Before making any decisions, a full assessment is essential. Our qualified arborists look at:
The overall health of the tree and extent of infection
Structural safety for people and property nearby
Whether treatment, monitoring, or removal is most suitable
The safest way to carry out any work given the tree’s location
The long-term survival prospects of the tree
This thorough process ensures you get tailored advice—whether that is ongoing monitoring, targeted treatment, or safe removal and replacement.
