Our garden is in southwestern Maine and we have a half dozen 30 year old blueberry bushes that have produced beautifully almost their whole lives (exceptions from weird spring weather). This year, though, the berries were sour. This was true for early and late varieties. Does anyone know what might cause this?
Also, I posted this here, because the Northeast is blueberry land. But also because I didn't see any other forum that looked appropriate. Did I miss one?
TIA
