I bought four mature 15 y/o Liberty blueberry plants from a blueberry farm for $40 each. Will they fruit this year?

They were bare root. The farm was transitioning to just hazelnuts. I added sulfur, used EBS Fert Rhody Azalea Camellia 6-4-3 fertilizer and added compost to the potting soil mix. Just don’t know if they will be shocked from the transplant.
