Cut the dead blooms back to where they attach to the stem. Doing this will ensure that your bush produce new flower buds longer into the blooming season than they would if the bush was left unattended. At the end of the season, you should dead-head all of the now finished blooms. This will help the plant along when creating buds for the next year.
