Red Robin hedge

I'm growing a Red Robin hedge, it's now about two and half years since I planted it. I have previously snipped off the growing tips to make them more bushy. They're looking fine, and are now over 2ft. At the moment they're starting to flower. Should I snip the flowers off to encourage more growth? I also think it's due another tip clip.

I've not grown Red Robin before so any advice is welcome

 

Hi

March is the ideal time to give them a trim to keep them in shape , enjoy the flowers a quick snip when they have FINISHED, let and insects enjoy a feed. Leaving them on causes no growth change.
Hope that helps
