Ask Burton: Q: My mature live oaks have struggled this year, and a tree guy driving up my street asking to trim trees let me know that I needed to treat my trees for oak wilt. He said that’s why my trees looked weak. They’re not as thick and healthy as last year, but they are still mostly green with only a few dead branches. Do I need to have him treat? He wants to use a spray.September 22, 2021
