Oak Wilt Treatment in Leander, Round Rock & Central Texas

Oak wilt is the single most destructive tree disease in Central Texas. It kills live oaks and red oaks — often the most valuable, oldest trees on a property — and it spreads underground through root grafts and above ground through sap-feeding beetles. Early diagnosis and correct treatment dramatically improve survival. Late diagnosis is often fatal to the tree.

Our Approach

Our Oak Wilt Treatment Process.

01

Diagnosis

Confirm oak wilt through leaf symptoms (veinal necrosis on live oaks, sudden crown decline on red oaks), pattern of spread, and if needed, lab confirmation.

02

Trench to sever root grafts

For oak wilt centers, install trenches 4 feet deep and 100 feet beyond infected trees to break underground root connections and prevent spread to neighboring oaks.

03

Propiconazole (Alamo) injections

Preventative fungicide injections applied to high-value uninfected oaks near known oak wilt centers. Effective for 2-3 years per treatment.

04

Correct pruning timing

Any oak pruning is done in dormant season (July-January) only, with wound paint applied immediately to every cut.

05

Monitoring

Ongoing evaluation of treated trees and surrounding canopy for early signs of spread.

Oak Wilt Treatment FAQ

Answers, straight from
the arborists.

How do I know if I have oak wilt?
Live oaks show yellowing veins on leaves (veinal necrosis) before dropping green leaves in summer. Red oaks show sudden crown-wide browning, often over just a few weeks. Rapid, unexplained decline of oaks — especially clusters of oaks — is the classic signal. Call for professional diagnosis before assuming.
Can oak wilt be cured?
Once a tree is symptomatic, cure is very difficult and outcomes vary. Preventative injections in high-value uninfected trees near known centers are more effective than reactive treatment.
When can I safely prune my oaks?
Only during the dormant season — July through January. Never from February through June, when sap-feeding beetles that spread the fungus are most active. Every cut must be sealed immediately with wound paint.
Should I treat all my oaks preventatively?
Not necessarily. Preventative injection is most cost-effective for high-value oaks near known oak wilt centers. If you don't have known oak wilt in your neighborhood, standard care (correct pruning timing, sealed cuts) is often sufficient.
