Sour Blueberries

Question

My blueberry plants are producing lots of berries, but they are all sour—any ideas?

Answer 1

Allow the berries to remain on the bush a little longer. They may not be fully ripened yet. Look for a dark navel when harvesting blueberries, not the color of the fruit. Blueberries with a reddish color around the stem end are not ripe, and will be tart. However, those left onthe bush to become fully deep blue will be ripe and sweet.
