How to prune mature blueberries

Asked January 4, 2014, 12:44 PM EST

We have 18 mature and very overgrown blueberries. We've read conflicting information online about how to prune them back to optimize fruit production. Some sites have said to remove all but a few major canes, while others have advocated a more conservative approach of removing 1 or 2 large canes / year until we are happy with the results. What do you recommend? Also, how many of the little branches should we remove? I'm considering removing anything that is less than roughly 1/4" in diameter, but that may be too drastic. There should be a picture attached. Thanks for any advice you can share.
