Non-blooming Hydrangea

Question

I have a firefly hydrangea that was planted last spring 2019. I have fertilized as I do all my other varieties of hydrangeas that bloom beautifully, but this one still hasn’t bloomed even this year. I live just outside Atlanta, Georgia. It is a beautiful plant and very healthy but won’t bloom. What am I doing wrong?

'Firefly' is a macrophylla which can be tricky to prune. Most should only be pruned after flowering. The Firefly, which should bloom most of the summer, can be lightly pruned in late winter to just remove the previous year's flower heads and any dead wood. This article should help:
