Heading into spring 2026, oak wilt remains the most consequential tree disease facing the Dallas-Fort Worth metroplex. Mild winter conditions and continued urban tree stress mean our arborists expect another active treatment season, and the next few months are the highest-leverage window to protect the oaks on your property.
What we are seeing on the ground
Across our service area, from inner-loop Fort Worth and Dallas neighborhoods out to Granbury, Glen Rose, and Weatherford, we continue to see clustered live oak decline in established subdivisions where root systems are interconnected. The pattern is consistent with how oak wilt spreads underground: one infected tree, then two or three neighbors over the following 12 to 18 months.
The bigger story for 2026 is the cost of waiting. Property owners who reach out at the first signs of oak wilt are saving 70 to 90 percent of their canopy with a single treatment cycle. Those who wait a season or two often need 2 to 3 cycles and still lose half the tree.
What to do this spring
- Walk your property in March and April looking for the classic veinal necrosis pattern on live oaks (yellow veins turning brown while the leaf is still green).
- Do not prune oaks until late June or wait until winter. Pruning wounds in spring attract the sap-feeding beetles that spread oak wilt above ground.
- If a neighbor has lost an oak, assume your oaks within 50 feet are at root-graft risk. A preventive injection now is dramatically cheaper than a therapeutic injection later.
- Get a free property walk from one of our ISA Certified Arborists. We will diagnose, identify risks, and tell you honestly if your trees need treatment or just monitoring.
Treatment pricing in 2026
Our published 2026 oak wilt treatment pricing reflects current fungicide costs and our Texas A and M-recommended macro-infusion protocol. Most single-tree treatments fall between $250 and $1,500 depending on diameter; multi-tree quotes typically come in 10 to 20 percent lower per tree.
