Oak wilt, caused by the fungus Bretziella fagacearum, is a significant threat to oak trees in Central Texas, causing widespread devastation. As experts in tree care, Wilder Tree Company is dedicated to helping you understand and manage this disease.
What is Oak Wilt?
Oak wilt obstructs the water and nutrient transport system of oak trees. The disease progresses from the top of the tree downwards, making it difficult for the tree to nourish itself. Red oaks, live oaks, and white oaks are all susceptible to varying degrees.
Identifying Susceptible Trees
All common Central Texas oak trees can contract oak wilt. It’s important to note that other tree species like cedar, elm, maple, and others are not susceptible to this disease.
The Danger of Oak Wilt
The impact of oak wilt varies among species:
Red Oaks: Highly susceptible, often dying within 4 to 6 weeks of infection.
Live Oaks: More resistant, but most infected trees die within 2 years.
White Oaks: Show the highest resistance, with many surviving despite canopy loss.
How Does Oak Wilt Spread?
Oak wilt can spread through root connections between trees or by sap beetles that carry the fungus from infected to healthy trees. It’s crucial to promptly seal all oak tree wounds, especially during spring and early summer, to prevent beetle attraction.
