Tree Stump Fungus: What It Means and How to Handle It

Fungal growth on or around a tree stump is a common sight in many gardens and green spaces, but it’s often misunderstood. While some fungi are harmless or even beneficial to the environment, others may signal decay or present a risk to surrounding vegetation and structures.

At Borrowash Tree Surgeons, we regularly advise homeowners and landowners in Borrowash, Derbyshire on how to manage fungal issues associated with old or recently felled trees. If you’ve noticed mushrooms or fungal patches growing on a stump, here’s what you need to know.

What Causes Fungus to Grow on Tree Stumps?

Fungi thrive in moist, shaded environments rich in decaying organic matter. A tree stump, particularly one left untreated after felling, provides the perfect conditions for fungal growth.

The presence of fungus typically means:

• The stump is undergoing natural decay.
  
• The wood has retained moisture, encouraging fungal spores to colonise.
  
• There may be hidden root rot beneath the surface.
  

Some fungi are purely decomposers, breaking down the dead wood over time. However, others may spread to healthy trees or signal a more significant issue with the root system.

Common Signs of Tree Stump Fungus

If you suspect fungal activity, look for the following indicators:

• Mushrooms or toadstools sprouting from the stump or ground around it
  
• Spongy, crumbly, or softened wood
  
• Discolouration or white fungal threads (mycelium) on the surface or base
  
• A sour, earthy smell indicating rot
  

While not all fungi are toxic or dangerous, it’s essential to identify the type of growth and assess any risks to the surrounding landscape.

Why You Shouldn’t Ignore Tree Stump Fungus

Leaving a stump untreated can result in more than just unsightly growth. At Borrowash Tree Surgeons, we’ve seen several reasons why prompt attention is important:

Risk to Healthy Trees

• Some fungal species spread through underground root systems.
  
• This can lead to infections such as Armillaria (honey fungus), which can attack nearby trees and shrubs.
  

Pest Attraction

• Rotting wood and fungus often attract insects like termites, beetles, or ants.
  
• This may increase the likelihood of pest problems spreading to nearby structures.
  

Structural and Safety Hazards

• Decaying stumps become unstable over time.
  
• They can create trip hazards or collapse, especially in high-traffic areas.
  

Delayed Garden Projects

• Fungal spread can disrupt plans for landscaping, planting, or building work.
  
• It can also interfere with turfing or laying new surfaces.
