Growth Stages

1

Establishment

4-8 weeks

New bareroot or container rose is planted with developing root system and minimal top growth

Water thoroughly after planting. Mulch around base with 2-3 inches of organic material. Avoid fertilizing for first 4-6 weeks. Prune back dead wood and weak canes.

2

Vegetative Growth

3-4 months

Bush produces new canes and foliage, establishing structure and vigor

Remove any flowers or flower buds to encourage strong vegetative growth in first year. Apply balanced rose fertilizer every 4-6 weeks. Maintain consistent watering. Monitor for pests and diseases.

3

Flowering

6-8 weeks, repeats throughout growing season

The plant produces abundant, highly fragrant fully double pink-mauve flowers in clusters

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.

4

Mid-Summer Rest

4-6 weeks

Reduced flowering during hottest months, especially in zones 8+

Reduce nitrogen fertilizer. Maintain consistent watering. Light deadheading. Prune back by one-third to encourage fall blooms.

5

Fall & Dormancy

8-12 weeks

Flowering 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.

Harvest Tips

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.
