Daniel, with your mild winter temperatures I doubt that your roses will ever go dormant , thus stop growing. Actually, its the best time to separate your mini roses into much larger pots. This should be done carefully trying to maintan the roots as closely intact as possible. However you need not to fret if some are broken in the way. Follow schramd's advice and cut above the bruised part. The root system will quickly replace with new roots.
