Do I thin these out ???

I have a lovely rose bush that gives flowers at the end of the stems. However, they grow in clusters of four or five and I never know whether to maybe cut a couple off to give the remaining ones more energy. What do you advise?

 

Not necessary, I think it's a floribunda type so it's meant to have multiple flowers
Some one else with more rose experience might have a more definitive answer

 

No, leave all the flowers to open and just prune those out that have died.

 

Thanks for advice. I will leave them be!
