Understanding Honey Fungus: Identification, Risks and Treatment

Over recent weeks, Elite Tree Services has received numerous enquiries regarding honey fungus, a serious and potentially destructive fungal infection that can affect trees, shrubs and garden plants. If left unchecked, honey fungus can cause significant damage to your landscape. In this blog, we explain what honey fungus is, how to identify it and what steps can be taken to manage or remove it.

What is Honey Fungus?

Honey fungus refers to a group of fungi in the genus Armillaria, which are notorious for attacking a wide range of trees and woody plants. These fungi live in the soil and spread through root systems, often going unnoticed until visible symptoms appear. The name “honey fungus” comes from the honey-coloured, clustered mushrooms that appear at the base of infected trees or stumps, typically in autumn.

Signs of Honey Fungus Infection

Early detection is crucial to prevent widespread damage. Some common signs include:

• Mushroom clusters: Small, honey-coloured mushrooms at the base of trees or shrubs, often appearing in autumn.
• Dieback: Progressive leaf yellowing, wilting, or branch death from the canopy downwards.
• Root decay: Soft, brown, or rotting roots can indicate the fungus is attacking the tree from underground.
• Black “bootlace” rhizomorphs: String-like fungal structures that spread through the soil, visible when you remove soil around the roots.
• Tree instability: In severe cases, the structural integrity of the tree is compromised, increasing the risk of branches or the entire tree falling.

Risks Posed by Honey Fungus

Honey fungus is highly aggressive and can spread quickly through root systems and soil. It can infect healthy trees as well as stressed or weakened ones, often leading to the death of shrubs, hedges and even mature trees. Gardeners and property owners should take it seriously, as it may threaten multiple plants and trees in close proximity.

Managing and Treating Honey Fungus

While honey fungus is difficult to eradicate completely, Elite Tree Services can help manage and mitigate its impact:

1. Professional assessment – Our arborists inspect your trees and soil to confirm the presence of honey fungus and assess the risk.
2. Tree and shrub removal – Severely infected trees or shrubs may need to be removed to prevent further spread.
3. Stump and root removal – Because honey fungus survives on stumps and roots, complete removal or grinding is often necessary.
4. Soil treatment and monitoring – While fungicides are largely ineffective once established, improving drainage and removing infected material can slow the fungus’s spread.
5. Planting resistant species – For future landscaping, we can recommend species less susceptible to honey fungus.
