Find Out What Is Really Wrong with Your Tree Before You Spend Money Fixing the Wrong Problem
Wild Oak Tree Service diagnoses tree diseases and decline across Austin, San Antonio, and the surrounding Hill Country. Yellowing leaves, dead branches, peeling bark, or mushrooms at the base can each point to several different causes, and the right treatment depends entirely on which one it is.
A clear diagnosis tells you what the problem is, whether it can spread to your other trees, and whether the tree can be saved, so you can decide on treatment, pruning, or removal with confidence.

Why Tree Diagnosis Matters in Central Texas
Central Texas is hard on trees. Long droughts, summer heat, shallow rocky soil, and alkaline ground put trees under constant stress, and stressed trees are the ones diseases and insects attack first. Several problems common in this region also look alike at a glance: drought stress, oak wilt, bacterial leaf scorch, and root damage can all produce browning leaves and thinning canopies.
Treating by guesswork wastes money and time. Some diseases respond well to early treatment, some cannot be cured and need to be managed, and some mean the tree has become a safety risk. A few, like oak wilt, can spread to neighboring trees if nothing is done. Knowing which one you are dealing with is the first step.
Signs Your Tree May Be Sick
- Leaves turning yellow, brown, or scorched out of season
- Browning along the leaf veins, or from the leaf edges inward
- Sudden wilting or heavy leaf drop in spring or summer
- Dead branches or bare patches in the upper canopy
- Bark cracking, peeling, or falling away from the trunk
- Oozing, dark staining, or sunken areas on the bark
- Mushrooms, conks, or other fungal growth on the trunk or around the base
- Small holes, sawdust, or tunnels in the bark
- Black, sooty coating on leaves and branches
- Several trees of the same kind declining in the same area
Common Tree Diseases and Problems We Diagnose
Oak Wilt
Oak wilt is the most serious tree disease in Central Texas and a major threat to live oaks and red oaks. Key signs include yellow or brown discoloration along the leaf veins, rapid leaf drop, and a spreading group of dying oaks. Because it moves through connected root systems, early diagnosis matters for every oak nearby. When we confirm oak wilt, our Oak Wilt Diagnostic and Treatment service covers the next steps.
Hypoxylon Canker
Hypoxylon canker is a fungus that takes hold in trees already weakened by drought, root damage, or construction, and it is common on oaks in this region after dry years. The telltale sign is bark sloughing off in patches to reveal a crusty fungal layer underneath that may be tan, silver, brown, or black. There is no cure once a tree is heavily infected, and the wood decays quickly, so affected trees often become hazardous and need to be evaluated for removal.
Bacterial Leaf Scorch
Bacterial leaf scorch is caused by a bacterium that lives in the tree’s water-conducting tissue and is spread by leafhoppers and other sap-feeding insects. It commonly affects oaks, elms, sycamores, and maples. Leaves brown from the edges inward, usually in mid to late summer, often with a yellow band between the dead and green tissue. The disease cannot be cured, but good care and, for valuable trees, targeted treatment can slow the decline.
Cotton Root Rot
Also known as Texas root rot, cotton root rot is a soil fungus that thrives in the alkaline soils found across much of Central Texas. Affected trees and shrubs wilt suddenly in summer, often dying within days, with the dead leaves still attached. Fruit trees and many ornamentals are especially vulnerable. Identifying it helps you choose replacement plants that will not suffer the same fate.
Root Rot and Wood Decay
Mushrooms or shelf-like conks at the base of a tree or on the trunk usually mean a decay fungus is breaking down the wood inside. The tree may still look healthy on top while its roots or trunk lose strength. Decay is a structural concern as much as a health one, so we assess how much sound wood remains and whether the tree is safe to keep.
Leaf Spots, Anthracnose, and Powdery Mildew
Spots, blotches, and white powdery coatings on leaves are common after wet springs. They look alarming but are usually cosmetic and rarely threaten a healthy tree. A diagnosis can confirm that no treatment is needed, which saves you from paying for one.
Insects and Sooty Mold
Borers tunnel under the bark of stressed trees, and scale insects and aphids produce a sticky honeydew that grows a black sooty mold, a common sight on crape myrtles in Austin. The mold itself is not the problem; the insects are, and treating the insects clears the mold.
Problems That Look Like Disease, but Are Not
Many trees we are called to look at are not diseased at all. Common look-alikes include:
- Drought stress: scorched leaf edges and early leaf drop, often showing up months after the dry spell
- Iron chlorosis: yellow leaves with green veins, caused by alkaline soil keeping the tree from absorbing iron
- Root and construction damage: trenching, soil grade changes, or compacted soil over the roots can cause decline years later
- Herbicide injury: curled or distorted leaves after nearby weed treatment
- Ball moss: it grows on the tree but does not feed on it, so removing it will not cure a tree that is declining for another reason
Telling these apart from disease is a large part of what a diagnosis does, and it often means the fix is simpler and less expensive than expected.
How Our Tree Disease Diagnosis Works
We Start with the History
We ask when you first noticed the problem, how the tree has been watered, and whether there has been recent construction, trenching, storm damage, or chemical use nearby. We also look at whether other trees on the property or next door are showing similar signs.
We Examine the Whole Tree and Its Surroundings
We inspect the canopy, leaves, branches, trunk, bark, and root flare, along with the soil and the tree’s position relative to other trees, buildings, and paving. The pattern of symptoms, which parts of the tree are affected and how, is often what separates one cause from another.
We Test When It Is Needed
Some diseases cannot be confirmed by eye alone. When a visual diagnosis is not conclusive, lab testing is available to confirm the cause before any treatment is recommended.
We Explain What We Found and What to Do Next
You get a straightforward explanation of the problem and your options. Depending on what we find, the recommendation may be:
- No treatment needed
- Continued monitoring
- Improved watering, mulching, or soil care
- Pruning out infected or dead wood
- Treatment
- Further testing
- Tree removal, when the tree cannot be saved or has become unsafe
