give them time..you may have to wait another year before your see fruit..that is if the squirrels and birds don't get to them first..

you said they did fairly well in 2014, did you have fruit then? fertilizing certainly helps. with all of the rain you've had you may also want to check the acidity level of your soil again..good luck.

Did you have any flower blossoms on your bushes? And if you did, that doesn't necessarily mean fruit. I had such an abundance of blossoms on my blueberries (4 different kinds for pollination) but only about half of those turned into fruit. No pollinators! What happened to them? Same thing with my currants. But if you had flowers, the soil is probably okay, since you have new foliage. I did lose two bushes because of the severe cold, but that doesn't sound like your problem. My blueberry output is about half of what it was last year, while my raspberry output is doubled.
