Eventually, water transport slows and stops, leading to the wilting effects. Tree death in red oak is rapid and can occur within three to four weeks after symptoms first appear. Six to 12 months after the tree has died, the fungus will complete its life cycle by producing spores on mycelial mats (Photo 1D).

How do you stop oak wilt from spreading?

Oak wilt can also be spread tree to tree through root grafting. The only currently recognized way to prevent the spread through root grafts is to root-prune the infected tree(s), severing all roots that can connect to surrounding oaks. Root pruning is typically done using a vibratory plow pulled behind a large tractor.
