If you have noticed mushrooms, fungal growth, or unusual clusters appearing at the base of a tree in your yard, it is important to pay attention. While some mushrooms in the landscape can be harmless, fungi growing directly at the base of a tree often signal serious internal issues that could put the tree—and your property—at risk.
At Grade-A Tree Care, our Plant Health Care specialists know what to look for and how to act quickly to protect your landscape. Here’s what you need to know if you spot fungi at the base of your trees in Kansas City.
Why Fungi Appear at the Base of Trees
Fungal growth at the base usually indicates one major problem: decay. When a tree’s roots or lower trunk are damaged or dying, fungi often move in to feed on the decomposing wood.
Common causes of decay include:
- Root rot from poor drainage or overly wet soil
- Injury from lawnmowers, string trimmers, or nearby construction
- Natural aging and weakening over time
Previous pest or disease damage that weakened the tree’s structure
Signs the Tree May Be in Trouble
The fungi themselves are not necessarily the primary issue—it is the health of the tree they indicate that matters. Additional signs of concern include:
- Soft, spongy wood near the base of the tree
- Cracks, hollows, or cavities in the trunk
- Trees that lean suddenly or show exposed root systems
- Thinning canopies or the presence of dead branches
- Sudden limb failure during storms or high winds
These symptoms may suggest that the tree’s internal structure is compromised and could eventually lead to failure.
What to Do If You Spot Fungi
- Schedule a Professional Tree Inspection – A trained arborist can assess the extent of internal decay and recommend the best course of action.
- Avoid Disturbing the Area – Digging or damaging the base could worsen the issue and accelerate the decay.
- Consider Tree Removal if Necessary – If a tree is determined to be hazardous, timely removal may be the safest option to protect your property and loved ones.
The earlier you act, the better your chances are of saving the tree—or ensuring that a hazardous tree is removed safely.
Preventing Fungal Problems in Trees
Although not every case of decay can be prevented, good tree care practices can significantly reduce the risk:
- Mulch properly with 2 to 3 inches of material, keeping mulch a few inches away from the trunk.
- Water deeply and appropriately, avoiding overwatering that leads to root rot.
- Protect trunks from damage by lawn equipment and avoid injury to the root zone.
Schedule annual health assessments with a certified arborist to catch early warning signs before they become major problems.
