Why are my hydrangea flowers dying, but the leaves look OK?

Question

I bought some Hydrangeas in pots in full flower. They were then left un-watered. They are now suffering from dead flowers but the leaves look OK. It is now August in North Yorkshire. Any ideas what I should do?

Answer 1

If the leaves look fine, it was probably caused by dehydration. Mine did that recently, as well. Cut the flower heads off, and keep the plant well watered.
