Hi, I'm wondering what might be wrong with my blueberry. It's the only one of several that has this problem. I bought it about two years ago from a local nursery. Could it be red ringspot? Thanks!
Benton County Oregon blueberries
This blueberry has the symptoms of blueberry shock. See the following web site: https://pnwhandbooks.org/plantdisease/host-disease/blueberry-vaccinium-corymbosum-shock
Blueberries with shock usually out grow the virus and return to full production with good care.
See cultural controls.
