Tree Health & Disease Treatment in Katy, TX
A sick tree doesn't always look sick — at least not at first. Many tree diseases are treatable if caught early.
Common Tree Diseases in Fort Bend County
Oak Wilt
The most destructive tree disease in Texas. Blocks water transport, causing rapid wilt and death. Live oaks can die within weeks. Spreads through root grafts and sap beetles. Early intervention is critical.
Hypoxylon Canker
Stress-triggered fungal disease attacking weakened hardwoods. Appears as silvery or brown fungal mats beneath bark. No cure; management focuses on removing affected wood and improving overall health.
Root Rot (Phytophthora)
Thrives in poorly drained soils — common in Fort Bend County's heavy clay. Symptoms include yellowing leaves and crown die-back. Improving drainage and systemic fungicide treatments can help early cases.
Cotton Root Rot (Texas Root Rot)
A Texas-specific soil-borne disease that thrives in alkaline, poorly draining soils. Trees can collapse quickly with little warning. No effective cure once infected.
Fire Blight
Bacterial disease affecting fruit trees, ornamental pears, and crabapples. Causes branch tips to die back suddenly with a "scorched" appearance. Affected branches need pruning with sterilized tools.
Signs Your Tree Is Sick
- Sudden or premature leaf drop — especially in spring or summer
- Leaf discoloration — yellowing, browning edges, or scorched appearance
- Thinning canopy — fewer leaves than prior years
- Dead branches — limbs that fail to leaf out through the season
- Fungal growth — mushrooms at the base, conks on the trunk, powdery patches under bark
- Bark abnormalities — cracks, sunken areas, weeping sap
- Wilting despite adequate water — often a vascular disease
Oak Wilt Treatment
Oak wilt requires immediate, aggressive action. Treatment typically involves:
- Propiconazole injections — systemic fungicide injected directly into the vascular system
- Root graft disruption — trenching to sever connections between infected and healthy trees
- Tree removal — in advanced cases, prompt removal protects surrounding trees
- Monitoring and follow-up — treatment isn't always one-and-done
If you suspect oak wilt, contact us immediately — don't prune the tree yourself (fresh wounds attract the beetles that spread the disease).
Tree Disease Treatment Options
- Systemic fungicide injections — delivered directly into the vascular system
- Soil drenches and root zone treatments — for root-level issues
- Targeted pruning — remove infected material with sterilized equipment
- Fertilization and soil amendment — strengthen overall tree health
- Drainage improvement — address underlying conditions for root rots
We also coordinate with our ISA-certified arborist consultation process when disease diagnosis requires formal assessment.
When Disease Means Removal
Not every sick tree can be saved, and not every tree should be. When a tree is in advanced decline, poses structural risk, or is actively spreading disease to healthy trees nearby, removal is the right call. We'll give you an honest assessment. If treatment has a realistic shot, we'll tell you. If the tree is past saving, we'll tell you that too — and we'll handle the removal cleanly, including stump grinding and proper disposal to prevent disease from lingering.
Don't Sit on a Sick Tree
Fast action is the difference between treatment and loss.
