Growth Stages

1

Establishment

2-3 weeks

Young transplants with initial leaf development and root establishment

Plant in spring after last frost. Water regularly to establish roots. Apply light mulch 1-2 inches from stem. Avoid fertilizing immediately.

2

Vegetative Growth

3-4 weeks

Bush develops multiple canes and dense foliage; plant reaches mature shape

Begin feeding with rose fertilizer every 2-3 weeks. Pinch back stems to encourage bushiness. Remove any diseased foliage. Ensure adequate air circulation.

3

Early Blooming

2-3 weeks

First flower buds appear and initial blooms open in scarlet red

Continue fertilizing on regular schedule. Deadhead spent blooms promptly to encourage reblooming. Monitor for pests and disease.

4

Continuous Flowering

12-16 weeks (summer through fall)

Plant produces abundant clusters of small double scarlet flowers throughout season

Maintain consistent watering and feeding every 2-3 weeks through summer. Deadhead regularly. Prune out crossing canes or weak growth.

5

Dormancy/Winter Preparation

October-March (varies by zone)

Growth slows, flowering decreases, foliage may turn reddish; plant enters rest period

Reduce watering and fertilizing. Prune back by one-third in late fall. Mulch heavily (4-6 inches) in zones 5-6 for winter protection. Remove dead wood in spring.
