Good morning all.. Would any who know advise me on the proper pruning technique/timing of Photina shrubbery.This is a short growing season area(well outside of the med. climate)and dont want to jeapordize this lovely shrub that has done so well for me here in the high desert of Idaho(zone5/6).It has some "loose"limbs that are flopping down of their own weight and just generally needs grooming. Thanks... Connie Hoy
