Oak Wilt Treatment

Oak Wilt in Fort Worth, TX: Identification, Risk, and Science-Based Treatment

Oak Wilt is one of the most serious vascular diseases affecting oak trees across Fort Worth and the greater North Texas region. Caused by the fungus Bretziella fagacearum, this disease disrupts the tree’s ability to transport water through the xylem, leading to canopy decline, rapid defoliation, and often tree death if left untreated.

In Fort Worth’s climate—where Live Oaks and Red Oaks are common landscape trees—Oak Wilt spreads both through root graft transmission and sap-feeding beetles attracted to fresh pruning wounds. Early detection and science-based treatment significantly improve the probability of preserving valuable trees.
