I have two different varieties of rabbiteye blueberries growing in containers. This will be their 4th fruiting season. Last year, I had great fruit set but all the blueberries on both bushes tasted like nothing, no matter how long I left them on the bush to ripen. Should I be thinning out the fruit at all? I included a photo of the slightly smaller of the two to give an idea of the size of the bushes.
