I’ve never heard so…
Fruit is a big biological demand, so I’m wondering about stresses that don’t kill the plant. A very specific nutrient deficiency? Does your state Extension have any suggestions?
… our state Extension! Phooey, I don’t see anything that looks similar but there are far more blueberry diseases than I’d realized…
