A sick tree doesn't always look sick — at least not at first. By the time most homeowners in Katy and Fort Bend County notice something is seriously wrong, the disease has often been active for months. The good news: many tree diseases are treatable if caught early. Fort Bend Tree Pros provides tree disease treatment in Katy TX and across Fort Bend County, with the expertise to identify what's wrong, recommend the right treatment, and help you save trees that are worth saving — and remove the ones that aren't.

Common Tree Diseases in Fort Bend County

Our Gulf Coast climate — hot, humid summers with periodic drought stress — creates conditions that favor a specific set of tree diseases. Here are the ones we see most often in the Katy and Fort Bend area:

Oak Wilt — The most destructive tree disease in Texas. Oak wilt is a fungal disease that blocks water transport inside the tree, causing rapid leaf wilt and death. Live oaks can die within weeks of showing symptoms; red oaks are especially vulnerable. It spreads through root grafts between neighboring trees and through sap-feeding beetles. Once a live oak loses 30–40% of its canopy, the prognosis is usually poor. Early intervention is critical.

Hypoxylon Canker — A stress-triggered fungal disease that attacks hardwoods — particularly oaks — that are already weakened by drought, construction damage, or root compaction. It appears as patches of silvery or brown fungal mats beneath the bark and typically signals a tree that is already in terminal decline. There is no cure; management focuses on removing affected wood and improving tree health where possible.

Root Rot (Phytophthora) — Caused by water mold rather than a true fungus, Phytophthora root rot thrives in poorly drained soils — a common issue in Fort Bend County's heavy clay. Symptoms include yellowing leaves, die-back from the crown down, and a tree that just looks "off" without obvious cause. Improving drainage and applying systemic fungicide treatments can help in early-stage cases.

Cotton Root Rot (Texas Root Rot) — A Texas-specific soil-borne fungal disease that attacks a wide range of trees and plants. It thrives in alkaline, poorly draining soils — again, exactly what we have in parts of Fort Bend County. Trees can collapse quickly with little warning. There is no effective cure once a tree is infected; the focus is on prevention and removing infected material to slow spread.

Fire Blight — A bacterial disease that primarily affects fruit trees, ornamental pears, and crabapples. It causes branch tips to die back suddenly, giving a "scorched" appearance. Affected branches need to be pruned out with sterilized tools to prevent spread through the tree and to neighboring plants.

Signs Your Tree Is Sick

Early detection makes all the difference. Watch for these warning signs:

Sudden or premature leaf drop — Especially in spring or summer when the tree should be leafing out fully
Leaf discoloration — Yellowing, browning edges, or leaves that look scorched without heat damage
Thinning canopy — Fewer leaves than prior years; light coming through where it didn't before
Dead branches — Limbs that fail to leaf out and stay dead through the season
Fungal growth — Mushrooms at the base, conks (shelf fungi) on the trunk, or powdery/silvery patches under bark
Bark abnormalities — Cracks, sunken areas, weeping sap, or areas where bark is slipping
Wilting despite adequate water — A tree that droops and wilts when soil moisture is fine is often battling a vascular disease

If you're seeing any of these symptoms, don't wait. The longer a disease progresses, the fewer options you have.

Oak Wilt Treatment

Oak wilt requires immediate, aggressive action. Once confirmed, treatment typically involves:

Propiconazole injections — A systemic fungicide injected directly into the tree's vascular system; most effective in early-to-mid stage infections on live oaks
Root graft disruption — Trenching or using a root barrier to sever the root connections between infected and healthy trees, preventing the disease from spreading through the grove
Tree removal — In advanced cases or for red oaks (which spread the disease heavily), prompt removal is the responsible choice to protect surrounding trees
Monitoring and follow-up — Treatment isn't always a one-and-done; we follow up to assess response and adjust as needed

Timing matters enormously with oak wilt. A tree treated in early stages has a significantly better survival rate than one treated after the disease has progressed. If you suspect oak wilt, contact us immediately — don't prune the tree yourself (fresh wounds attract the beetles that spread the disease) and don't delay.

Tree Disease Treatment Options

Depending on the disease, treatment options include:

Systemic fungicide injections — Delivered directly into the tree's vascular system for maximum uptake
Soil drenches and root zone treatments — For root-level fungal and bacterial issues
Targeted pruning — Remove infected material to stop disease spread; all cuts made with sterilized equipment
Fertilization and soil amendment — Strengthen overall tree health to improve resilience and disease resistance
Drainage improvement — Addressing the underlying conditions that allow root rots to thrive

We also coordinate with our ISA-certified arborist consultation process when disease diagnosis requires a formal assessment or documentation.

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 — and delaying it makes the situation worse and more expensive.

We'll give you an honest assessment. If treatment has a realistic shot at working, we'll tell you. If the tree is past the point of saving, we'll tell you that too — and we'll make sure the removal is handled cleanly and completely, including stump grinding and proper disposal to prevent disease from lingering in the soil or wood debris.
