Rust on leaves won’t kill ash trees

Orange and yellow “measles” cover the leaves of Pat Richardson’s backyard ash tree in southwest Omaha.
Fearful for the health of her tree, she went looking for answers.
She’s not alone.
“We’ve had hundreds of people coming in this year, wondering what’s wrong with their ash trees,” said Mary Anna Anderson of the University of Nebraska Extension in Douglas and Sarpy Counties.
Those bumpy orange spots are caused by ash rust, a windborne fungus.
Diseased leaves will drop this summer, but people shouldn’t be alarmed, Anderson said. The tree should releaf, and its overall health shouldn’t be affected.
