I have a Hydranga and year after year I get masses of flower heads but for some reason these only have a few flowers open on each. No big heads. What is the matter and what can I do to get it to produce the heads it should have?

Yes it does sound like a Lacecap, they have open flowers round the edge of the of the rather flat flower head, .

You sure you haven't got a lacecap variety rather than a mophead? Do you have a name for the plant? Otherwise, a photograph of the flowers would be good.
