The oaks that are particularly susceptible to Oak Wilt include:
- Red Oaks
- Spanish Oaks
- Shumard Oaks
- Blackjack Oaks
When planting trees consider planting Oaks that are not susceptible to Oak Wilt, including White Oaks such as:
- Post Oaks
- Bur Oaks
- Chinkapin Oaks
These are resistant to the fungus and seldom die from the disease. Also, consider planting other Texas Hill Country Native trees from a list compiled by the Native Plant Society of Texas Boerne Chapter.
Managing Oak Wilt
Oak Wilt can be managed in three basic ways:
- Prevention – Early detection and proper disposal of infected trees. Disinfect pruning tools prior to cutting; use an all-purpose household disinfectant or denatured methyl/isopropyl alcohol. Paint all wounds immediately with latex or commercial tree wound paint. Avoiding pruning trees between February and June. Proper storage of firewood to prevent fungal mat spread. Planting trees that are not susceptible. Hire only qualified professionals to prune and maintain your trees.
- Containment - Trenching 100 feet from infection area and severing of all interconnecting roots.
- Fungicide Treatment - Fungicides used as a preventative treatment may show some success in the early stages of the disease.
