How Can I Tell If I Have Oak Trees?
How can I prevent Oak Wilt?
- Always paint fresh wounds on oaks, including pruning cuts and stumps, with a wound dressing or latex paint immediately after pruning or live tree removal at all times of the year.
- Clean all pruning tools with 10% bleach solution between sites and/or trees.
- If possible avoid pruning or wounding of oaks during the spring (currently defined as February 1 through June 30)
You may read on gardening or tree care sites about wound paints or sealers being toxic to trees or a bad, old school idea, but oak trees in Central Texas where oak wilt is prevalent are a clear exception to that assertion.
Regardless of the reasons or time of year, proper pruning techniques should be used. These techniques include making proper pruning cuts and avoiding injurious practices such as topping or excessive crown thinning. If you are uncertain about any of this information, you should consult with a Texas Oak Wilt Certified arborist, ISA Certified Arborist, or an oak wilt specialist from a city, county or state government agency such as the Texas A&M Forest Service or Texas A&M AgriLife Extension Service.
