A failing tree rarely comes down without warning. It usually shows signs for months or even years before it fails, and knowing what to look for lets you act before a limb lands on your roof, your car, or someone you love. North Texas trees face real stress from summer heat, drought, clay soil, and the ice and wind that roll through each year. Here are the warning signs our ISA Certified arborists watch for, and when it is time to call a professional.
1. Excessive Deadwood
A few dead twigs are normal, but large dead branches, or many of them, signal a tree in decline. Deadwood is brittle and unpredictable, and big dead limbs can break loose in a storm or even on a calm day. If you see bare, leafless branches scattered through an otherwise leafy canopy, the tree is telling you something.
2. A Thin or Bare Crown
The crown is the leafy top of the tree, and it is a good gauge of overall health. Warning signs include leaves that are sparse, undersized, or off-color, sections of the canopy that never leaf out in spring, or a general thinning you can see the sky through. When the top of the tree starts dying back, the problem often runs deeper than the branches.
3. Fungus and Mushrooms
Mushrooms or shelf-like fungal growth on the trunk, at the base, or over the root zone are a red flag. These fruiting bodies often mean the wood inside is decaying. Fungus growing where the trunk meets the soil is especially concerning, because that is exactly where a tree needs to be strongest to stay standing.
4. Soft, Hollow, or Crumbling Wood
Healthy wood is firm. If bark is falling away to reveal punky, crumbling wood underneath, or if the trunk sounds hollow when tapped, internal decay may be advancing. A hollow trunk does not always mean immediate failure, but it significantly weakens the tree and warrants a professional look to judge how much sound wood remains.
5. Cracks and Splits
Deep vertical cracks in the trunk, splits where two large stems meet, or seams that seem to be opening are structural warnings. Weak V-shaped unions where included bark is trapped between stems are prone to splitting, especially under the load of North Texas ice or high wind. Cracks that show up after a storm deserve prompt attention.
6. A Sudden Lean
Many trees lean a little and have grown that way for years, which is usually fine. What concerns an arborist is a new or sudden lean, particularly if you see soil heaving, cracking, or lifting on one side of the base. That can mean the root plate is failing and the tree is beginning to pull out of the ground. A tree that shifts after a storm should be treated as a potential emergency.
7. Root Damage and Trouble at the Base
Roots anchor the tree and feed it, and they are often the hidden source of decline. Watch for signs such as:
- Recent trenching, grading, or construction that cut roots near the tree
- Soil compaction from vehicles or equipment over the root zone
- Mushrooms, soft spots, or cavities at the root flare
- Heaving or lifting soil on one side of the trunk
Because root problems are hard to see, a tree can look fine up top while its anchorage quietly weakens.
When to Call a Professional
Any single sign is a reason to look closer, and several together mean it is time to bring in an expert. Call an arborist promptly if you notice a sudden lean, large dead limbs over your house or driveway, cracks in the trunk, fungus at the base, or any change after a storm. A certified arborist can assess the whole tree, judge how serious the risk is, and recommend whether it can be pruned and saved or needs to come down. Guessing with a large tree overhead is not worth the risk.
