Have you pruned your hydrangea? If you don’t prune at all, it may be something you want to consider. If you prune, your hydrangea stands a better chance of growing larger flowers. A hydrangea that isn't pruned tends to have smaller ones. Tips for pruning hydrangeas can be found here:

Barring that, you can give your hydrangea its best chance for big blooms by ensuring it is getting the care it needs with regards to watering, fertilizing, light, etc. - this article provides you with a plan of care:

I'm not an expert but do the roots have enough room in the soil?
