Oak wilt was recently confirmed in Steiner Ranch and managing the disease is difficult. Oak wilt spreads quickly, especially through tree roots, ultimately killing most trees that are susceptible.
“The rate of spread of the disease through the roots is approximately 75 feet per year,” said Clay Bales, Texas A&M Forest Service forester.
Once oak wilt infects an oak tree, the disease can spread through the roots to other oak trees. Out of all of the oak varieties, red oaks and live oaks are most susceptible to the disease.
Roots form a network underground which accelerates the rapid spread.
“Large live oaks can root-graft to other large live oaks up to 200 feet away,” Bales said.
