Flowering

Deadhead spent blooms to encourage repeat flowering. Apply rose-specific fertilizer to support continuous bloom. Maintain proper watering and air circulation. Stake if needed to support heavy flower weight.
Mid-Summer Rest

Reduce nitrogen fertilizer. Maintain consistent watering. Light deadheading. Prune back by one-third to encourage fall blooms.
Fall & Dormancy
8-12 weeksFlowering resumes in fall with cooler temperatures; plant gradually enters dormancy as day length decreases
Stop fertilizing 6 weeks before first frost. Reduce deadheading to allow hips to form. Withhold pruning until spring. In cold zones, mound soil 8-12 inches over base for winter protection.

Cut flowers in early morning when blooms are fully open but before peak heat. Cut stems at 45-degree angle above an outward-facing leaf node. Strip lower leaves and immediately place in cool water with floral preservative. Flore Pleno blooms are exceptional for fresh arrangements and dried flowers due to their petal density.
