What causes Mophead hydrangea blooms to be small?

Question

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?

Answer 1

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.
