Howdy Vicki , welcome to permies!
Do you remember if you had any bad weather, frost, hard rain, hail etc that might have damaged the flowers ?
Perhaps the plant is still getting settled in, it might do better next year? Is the rest of the plant healthy?
What PH is your soil generally?
I had been wanting to grow blueberries for several years but thought they were too difficult after reading up on the subject. I received one as a gift but it didn't like our soil. Here is a comment from "yahoo answers":
Fertilizing you're soil is basically a must, and keep in mind that you most likely won't harvest any blueberries for the first three years.
And this is from Mother Earth News:
Blueberries are only marginally self-fertile, so you’ll need to grow at least three plants of compatible varieties.
Most soils should be amended with 4 inches of acidic organic matter, such as rotted sawdust or leaf compost.
If your soil’s natural pH ranges between 5.5 and 6.0, you can further acidify it by top-dressing with soil sulfur twice a year. In areas with soil pH levels above 6.0, grow blueberries in large containers filled with a wood chip- or bark-based planting mixture.
