Oak wilt diagnosis & treatment in central Texas

Oak wilt is one of the most destructive tree diseases in central Texas, and it spreads fast through connected root systems and sap-feeding beetles. Catching it early is what protects the rest of your oaks and your neighbors’.

We diagnose oak wilt, advise on trenching to sever root connections, and guide treatment and pruning timing. The single most important rule is to avoid pruning oaks from February through June, when the beetles that spread the fungus are most active.
