Oak Wilt Management
Oak Wilt is one of the most destructive tree diseases affecting Central Texas, presenting itself in a handful of different ways, capable of killing healthy oak trees in a matter of weeks or months if left unmanaged. Throughout Dripping Springs, the Texas Hill Country, and the greater Austin area, thousands of oak trees are lost each year to this aggressive fungal disease. At Verde Lawn & Landscape, we provide professional oak wilt management in Dripping Springs, TX, combining early detection, science-based recommendations, and industry-approved treatment methods to help protect some of your property's most valuable assets. As a Texas Oak Wilt Qualified company through ISA with an ISA Certified Arborist on staff, we stay current with the latest research and best management practices recommended by the Texas A&M Forest Service and the International Society of Arboriculture to achieve proper Oak Wilt identification, management, and prevention. Every property and every tree is unique, which is why our approach begins with a thorough evaluation before recommending a management plan.
Oak wilt is caused by the fungus Bretziella fagacearum, which spreads in two primary ways. The first is through interconnected root systems, allowing the disease to move somewhat rapidly from one oak to another, particularly among live oaks and red oaks that commonly share root grafts beneath the soil.

second method of spread occurs when sap-feeding beetles are attracted to fresh wounds on infected red oaks and then carry fungal spores to newly wounded healthy oaks. Because of this, proper pruning practices are one of the most important preventive measures. In Central Texas, unnecessary pruning of oak trees should generally be avoided during the highest-risk period (February - June), and any fresh pruning cuts or storm damage should be properly painted immediately to reduce the risk of beetle transmission.
Successful oak wilt management depends on early diagnosis and a comprehensive treatment strategy. Symptoms such as rapid leaf drop, vein discoloration, browning leaf margins, canopy thinning, or sudden decline should always be evaluated by a qualified arborist, as many other conditions can produce similar symptoms. Correct diagnosis is essential before any treatment decisions are made. In many situations, laboratory testing may be recommended to confirm the presence of oak wilt and rule out other causes of decline.
When appropriate, management options may include fungicide injections for high-value trees, root disruption through trenching to slow underground spread, sanitation recommendations, and long-term monitoring of surrounding oaks. Preventive fungicide injections can be an effective tool for healthy trees that are at risk or near a disease center but have not yet become infected, while therapeutic treatments may help protect certain trees during the early stages of disease development. Because treatment success depends on timing, tree condition, and disease progression, prompt evaluation is critical whenever oak wilt is suspected.
At Verde Lawn & Landscape, we believe education is one of the most effective tools in preventing oak wilt. We work closely with homeowners to explain disease progression, identify trees at risk, and develop realistic management plans that protect both individual specimens and the surrounding landscape. Our recommendations are based on current arboricultural research—not unnecessary treatments or one-size-fits-all solutions. As a ISA Texas Oak Wilt Qualified company serving Dripping Springs, Johnson City, West Austin, and the surrounding Texas Hill Country, we are committed to helping property owners preserve the beauty, safety, and longevity of their oak trees.
