Blueberries aren't ripening

There has been loads of fruit on my blueberry plant for about 6 weeks now but they're still all a pale blue colour. Some of them have started to shrivel and fall off. The bush is in a pot of ericaceous peat-free compost in a south-facing border. Could the wrong type of fertiliser be causing this? I've been using tomato feed just out of habit but now I'm wondering if this could be the problem. If so, is there any way to get them to ripen?

    You'd need an ericaceous fertilizer really - I use Miracle Grow for Azaleas, once a month in the growing season.
    Use rainwater if possible too so that all the nutrients are accessible to the plant.
    Two bushes are recommended as well so you get good pollination.
    I doubt the feed alone is the cause of your problem, but i don't know why they're not ripening.

    I have 3 in big pots also in a southerly position and they're all cropping well.

    If you have a pic we may be able to come up with other ideas

    Blame the weather I suppose you’ve tried extra water

    Are you sure that the ‘pale blue’ isn’t simply the powdery ‘bloom’ on the ripe fruit?

    Have you tried any of the fruit? I would say mine go from green to purplish to light blue then they are ripe. I find that my blueberries have a lot more flavour than shop bought.
