Why have my blueberries stayed white, small and dropped off even though they have been fed and watered through the heatwave we've had? Some turned green but no blue and didn't even produce a hand full of them.
Outside United States blueberry production
I have two giant blueberry bushes, both same plants. Fruits started only in top branches. Climate is in North Wales UK. Both bushes were laden with fruit last year. My raspberries are close by and are fine.
