Why would some blueberries never ripen at all?
I have nine blueberry bushes that always produce beautiful berries. This year two of them still have berries that never ripened. At some point they just stopped ripening. Any ideas?

Are all nine the same variety? Since they have been producing in the past, I don't think it is the chill factor which is a common reason blueberries don't ripen. Lack of sun and high pH in soil are two more reasons. Is part of your blueberry patch getting shadier, such as trees growing larger canopies? Has anything affected soil pH? These are the most common reasons for lack of ripening. If none of these seem appropriate, try contacting your local cooperative extension agent for more information.
