Oak Wilt Reminder
Pruning oak trees is not allowed in Bee Cave between February 2 – June 30. This is to protect them from Oak Wilt, a deadly tree disease.
If an oak tree becomes damaged, it’s important to paint the wound immediately to block insects from transmitting deadly oak wilt fungus. This involves applying a sealant like pruning paint directly on the wound. If an oak tree becomes infected with oak wilt, it is often fatal so prevention is the best option.
A certified arborist can deploy methods to prevent Oak Wilt from spreading to new trees, but this is a costly procedure that can exceed thousands of dollars.
Oak wilt is evident in live oaks by yellow and brown veins showing in leaves of infected trees, known as veinal necrosis. The signs of oak wilt can be seen on a majority of leaves when a tree is fully infected.
Landowners should contact a certified arborist if they are unsure if their tree is infected.
According to the Texas A&M Forest Service, Oak Wilt is destructive to the ecosystem and the effects of oak wilt can also reduce property value by 15 to 20 percent.
