Hydrangea Not Blooming

We see no sign of disease on your plant, but you should know that not all hydrangeas will bloom reliably in your region. Do you know the exact cultivar name of this hydrangea? Some hydrangeas will produce flower buds that can be killed by a cold winter (like we had last year). The plant will live, but it won’t produce any flowers. Additionally, some hydrangeas bloom on old wood and others bloom on new wood or on both. If you have a hydrangea that blooms on new wood and you prune it every year, you’re cutting off the branches that would be producing flowers the next year. To find out the answers to these questions, we need to know what kind of hydrangea you have, and we can’t tell that from looking at the leaves alone.
