What causes Mophead hydrangea blooms to be small?
In past years the blooms were big, but this year I have lots of blooms but they are small. We had a hurricane and snow all in the same season. This is the second year after that. Is the plant still recovering?

What is your normal feeding routine? These should be fed once per year in early spring for best flowering. An all-purpose will suffice.
Is there an adequate amount of shade? Too much sun can stunt them as well.
