What is Oak Wilt?

Oak wilt is an infectious vascular disease that invades and disables the water conducting system in susceptible trees. All oaks can be infected with oak wilt.

Why should we be concerned with Oak Wilt Mitigation?

The City of Helotes is a known hot spot for oak wilt. The area is predominantly covered with live oaks. Live oaks tend to grow from root sprouts and can form root grafts very readily. All or most of the live oaks within a given area share a common root system. If one tree in a group of live oak trees becomes infected with oak wilt, then the pathogen can spread through the common root system at an average rate of about 75 feet per year.

How do we prevent Oak Wilt?

The City of Helotes has been actively combating oak wilt by enforcing Chapter 94-6 of the City’s adopted Vegetation Code, which incorporates the following:

  • (a) Applicability. Tree pruning restrictions shall apply to all real property within the City’s corporate limits and its extraterritorial jurisdiction.
  • (d) Branch/root pruning and wounded trees. All broken branches and exposed roots one-half-inch in diameter or greater of any protected, heritage, or replacement tree shall be cut cleanly. In the case of oak species susceptible to oak wilt, wounds must be painted with an acceptable wound dressing within 30 minutes from the time of cutting.
  • (e) Oak wilt. Trimming or cutting of any oak tree susceptible to oak wilt is prohibited within the corporate city limits and extraterritorial jurisdiction (EDJ) of the City of Helotes from the first day of February to the last day of May. Permission, however, may be granted to any entity wishing to trim or cut an oak tree susceptible to oak wilt during the prohibited months, provided that the entity contracts with an licensed professional tree care or landscaping company. The professional tree care or landscaping company shall obtain a permit from the City prior to any tree trimming, de-mossing, or removal in the City. In the case of oak species susceptible to oak wilt, wounds must be painted with an acceptable wound dressing within 30 minutes from the time of cutting. All trimming tools shall be cleaned with a disinfectant after each use to prevent spreading of the disease.

Residents can help prevent oak wilt by following these tips from Texas A&M Forest Services, 2020:

  • Avoid pruning or wounding oaks between February 1 and May 31 each year.
  • Sterilize/sanitize all pruning equipment between trees.
  • Immediately paint all wounds on oaks to prevent contact with contaminated beetles. Wounds can be either man-made or natural and include freshly cut stumps and damaged surface roots.
  • Promptly remove and, either burn or bury, all red oaks that are dying or have been recently killed by oak wilt.
