Presentation roses begin with perfect roses. Dry pack standard roses are shipped with guard petals still on the rose. Remove these only when you are ready to design.
Wash your hands before touching rose petals. I like to spray my fingers lightly with Finishing Touch to be sure that oils from my fingers don't transfer to petals, which could cause early browning and transparency. Peel away the damaged petals until you have a good, clean rose.
Good roses are firm to the touch and will hold up for several days. It is advisable to keep these roses refrigerated and take them with water tubes on the stems to the church, removing the tubes just before the ceremony.
