Mold, Fungus & Mushrooms on Trees: Should You Be Concerned?

If you’ve noticed mold, fungus, mushrooms, or unusual growth on a tree on your property, you may be wondering whether the tree is healthy or if it needs professional attention.

While some fungi are harmless, others can indicate serious decay, disease, or structural weakness that may increase the risk of tree failure.

Understanding the warning signs can help protect your property and determine whether tree pruning or tree removal may be necessary.

Why Is Fungus Growing on My Tree?

Fungi play an important role in nature by helping break down dead organic matter.

However, when fungus begins growing on living trees, it can sometimes indicate:

• Internal decay

• Root rot

• Disease

• Dead or dying wood

• Structural weakness

The presence of fungus does not always mean a tree needs to be removed, but it should not be ignored.

Common Signs of Tree Disease

Signs that a tree may be unhealthy include:

• Mushrooms growing on the trunk

• White, black, or orange fungal growth

• Soft or decaying wood

• Large dead branches

• Hollow areas in the trunk

• Peeling bark

• Sudden leaf loss

• Significant leaning

Trees showing multiple symptoms may require professional evaluation.

Are Mushrooms Growing at the Base of a Tree a Problem?

Mushrooms growing near the base of a tree can sometimes indicate root decay.

Root rot can weaken the tree’s support system and increase the risk of the tree falling during high winds or storms.

Because root problems often occur below ground, they can be difficult for property owners to assess on their own.

Can a Diseased Tree Be Saved?

In some cases, pruning and proper tree care can improve the health of a tree.

However, trees that are severely diseased, structurally compromised, or extensively decayed may require removal to prevent safety hazards.

Every situation is different and depends on:

• Tree species

• Age of the tree

• Extent of decay

• Location of the tree

• Overall health

  
  

When Should a Diseased Tree Be Removed?

Tree removal may be recommended when:

• The trunk is significantly decayed

• Large sections of the tree are dead

• Root systems are failing

• The tree poses a risk to people or property

• Storm damage has weakened the structure

Removing a hazardous tree before it fails can help prevent costly damage and emergency situations.
