I have some well-matured Potentilla shrubs, white and yellow, and groomed them down a lot during the late winter and early spring, which was quite cold here in Victoria. I had allowed them to get quite overgrown the previous Fall. They seemed very hardy. I have learned it is a mistake to prune that early. Now they are flush with leaf growth [they were also watered and fertilized well -- would that inhibit bloom in this species?], but there were no flowers or buds. I did re-prune to the rounded shape recently, and they look excellent with a full lush leaf-out. Since then some nice large flowers have appeared, but no flower flush. Would the recent re-pruning have stimulated some bloom? Any chance of flowers this summer? I presume if kept well trimmed until winter, but not early-pruned next spring [waiting until warmer weather] that they will bloom next year. I have read conflicting advice on how to stimulate bloom.
