my guess is that they won't actually produce a crop off these blooms... we'll probably get another freeze and they'll fall off. blueberries are а may-june crop.

standard practice is to fertilize them in february, then again in summer, and finally sometime mid-fall. better yet, fertilize them VERY LIGHTLY every couple of months. (that's what i do.)

whatever you do, make sure to read up on proper fertilization of blueberries--they are very sensitive to nitrogen and should be fertilized very lightly and carefully. here's the standard reference for blueberries in the home garden

Thanks for the link. Good info. These blueberries are in pots so I bring them inside if the temps drop at night. I'm hoping that will help encourage the buds they have produced to mature.
