9 Warning Signs Your Lewisville Tree May Be Suffering From Root Rot

Most homeowners don't think much about what's happening beneath the surface of their trees. After all, if the leaves are green and the canopy looks healthy, everything must be fine—right?

Unfortunately, some of the most serious tree problems begin underground, hidden from view. One of the most common and destructive issues is root rot. By the time visible symptoms appear, a tree may already be experiencing significant damage to its root system, making it vulnerable to decline, structural failure, or even complete collapse.

Understanding the early warning signs of root rot can help you protect your trees, your property, and your investment.

What Is Root Rot?

Root rot is a fungal disease that attacks a tree's root system when excessive moisture remains in the soil for prolonged periods. Poor drainage, overwatering, compacted soil, and extended periods of heavy rainfall can all create the perfect conditions for fungi to thrive.

Healthy roots absorb water and nutrients while anchoring the tree firmly in the ground. When root rot develops, these roots begin to decay, reducing the tree's ability to support itself and transport essential nutrients throughout the canopy.

Because the damage occurs underground, many homeowners don't realize there's a problem until symptoms begin appearing above ground.

9 Signs Your Tree May Have Root Rot

1. Yellow or Discolored Leaves

One of the earliest signs of root rot is foliage that begins turning yellow, pale green, or brown despite regular watering. When roots can no longer absorb nutrients properly, the canopy often reflects the problem first.

2. Slow or Stunted Growth

Trees affected by root rot often struggle to produce healthy new growth. Leaves may appear smaller than normal, and annual growth may noticeably decline.

3. Premature Leaf Drop

If your tree begins shedding leaves outside of its normal seasonal cycle, it may be experiencing stress caused by a compromised root system.

4. Soft or Decaying Wood Near the Base

Examine the trunk where it meets the ground. Soft spots, decaying wood, cavities, or deteriorating bark can indicate that fungal decay is spreading upward from the roots.

5. Peeling or Cracking Bark

Healthy bark should remain firmly attached to the tree. Bark that peels away easily, cracks excessively, or appears loose may signal underlying root problems.

6. Mushrooms or Fungal Growth

The appearance of mushrooms, shelf fungi, or other fungal growth around the base of a tree is often a warning sign that decay is occurring below the surface.

7. Foul Odors Around the Root Zone

Rotting roots frequently produce a musty or unpleasant smell. If you notice a persistent odor near the base of a tree, it may be time for a professional evaluation.

8. Leaning or Unstable Trees

As root systems weaken, trees lose their ability to remain firmly anchored. A tree that suddenly begins leaning or appears unstable should be inspected immediately.

9. Branch Dieback and Thinning Canopy

Dead branches, sparse foliage, and thinning canopies are often indicators that the tree is no longer receiving the nutrients and water it needs to thrive.

Can Root Rot Be Prevented?

While root rot can be difficult to reverse once it becomes severe, there are several steps homeowners can take to reduce the risk:

Avoid Overwatering

Many tree problems begin with excessive irrigation. Water deeply but infrequently, allowing the soil to dry between watering cycles whenever possible.

Improve Drainage

If water regularly pools around the base of your tree, consider improving drainage through grading, drainage systems, or other landscaping solutions.

Schedule Professional Tree Pruning

Proper pruning improves airflow and allows more sunlight to reach the soil, helping excess moisture evaporate more efficiently.

Monitor Trees Regularly

Routine inspections make it easier to identify potential issues before they become serious safety concerns.

Mulch Correctly

Apply mulch in a thin layer around the root zone, but avoid piling mulch against the trunk. Excess moisture trapped against the bark can contribute to decay.

Water During Daylight Hours

Watering early in the morning allows moisture to evaporate naturally throughout the day, reducing conditions that encourage fungal growth.

When Tree Removal Becomes Necessary

In some cases, root rot progresses to the point where a tree can no longer be safely preserved. Severely compromised trees may become unstable and pose a significant risk to homes, garages, fences, vehicles, and other nearby structures.

When a tree's structural integrity has been compromised, removal is often the safest option.
