Does oak wilt spread to other trees?
Yes. oak wilt moves to other trees, which is why one infected tree is a decision about the whole yard rather than about that tree. A red oak showing symptoms is usually lost within a season. The urgent job is protecting the oaks around it, because it moves underground through grafted roots.
