Question

Some hydrangeas only bloom on old wood, so if you trim them at the end of the season this could be the problem.

You might consider having your soil tested or think back to the last time you fertilized. Too much nitrogen or a lack of phosphorus in the soil could be the reason. An abundance of nitrogen produces lush green growth, but little to no blooms. Phosphorus is responsible for the flowering and fruiting in most plants, so the addition of a phosphorus-rich fertilizer may be all that is needed to correct this. Bone meal is also a great way to add phosphorus to the soil.

If you had the crazy warm February followed by the March freeze, the blossoms that were forming may have been killed. That happened to mine.

Are you trimming them? If so, just leave them alone until you determine what type they are. Some hydrangeas set out blooms on 'old' wood so if you trim the bush in the Spring, you may have accidentally cut off the coming year's blooms. Some hydrangea bloom on both old and new wood, therefore, trimming isn't so detrimental. Then there are other hydrangeas that bloom just on new wood. Go on a good plant site on the web and see if you can find out what type of hydrangeas you own.

How old are they? Did you cut them back? Hydrangeas bloom on the growth from 2 years ago. So be careful when pruning them to take the older growth off.
