Oak wilt FAQ: what to do if your oak is dying
My oak is dying. What should I do first?
1) Don't prune, cut, or wound any nearby oaks, especially February through June. 2) Take photos of the leaves (look for yellow veins turning brown) and of the whole tree. 3) Note whether nearby oaks or neighbors' oaks are also declining. 4) Get a qualified arborist or your Texas A&M Forest Service forester to diagnose it. A lab test confirms oak wilt. 5) Ask about protecting nearby healthy oaks, since the disease spreads through connected roots. 6) If it's a dead red oak, ask about prompt removal and proper disposal, and don't keep it as firewood.
Can a dying oak be saved?
Sometimes. Texas A&M sources say fungicide injection (propiconazole) is mainly preventive, or best used early. Badly affected trees, and almost all red oaks, usually can't be saved. No one can promise a result.
Is it definitely oak wilt?
Not always. Drought, root damage, and other problems can look similar. Veinal necrosis on live oaks is the best field sign, but a lab test confirms it.
Is there financial help?
Inside Boerne city limits, the city reimburses part of treatment and removal costs, subject to funding. Across Central Texas, Texas A&M Forest Service cost-share can cover up to 50% of approved trenching or red oak removal costs, approved before work starts.
Do you treat trees?
No. We are a free referral service that connects you with independent licensed arborists.
