Growth Stages

1

Dormancy/Spring Awakening

4-6 weeks

Rose emerges from winter dormancy with reddish new growth and emerging canes beginning to leaf out.

Prune dead canes in early spring. Remove winter mulch after last frost. Begin regular watering and feeding program.

2

Vegetative Growth

6-8 weeks

Vigorous leaf growth on new canes with increasing branch formation. Plant reaches its full seasonal height and develops dense foliage.

Apply balanced fertilizer every 4-6 weeks. Monitor for pests and diseases. Deadhead any early weak blooms to encourage stronger growth.

3

Bud Formation

2-3 weeks

Terminal buds form at cane tips, gradually swelling and taking on color. Individual sepals begin to show.

Continue regular watering and feeding. Increase phosphorus-rich fertilizer to support blooming. Monitor for spider mites.

4

Flowering

3-4 weeks per flush; repeat blooming throughout season

Large, double flowers with 20-40 velvety crimson petals open in succession. Blooms are fragrant and deep red, darkening as they age.

Deadhead spent blooms regularly to encourage continuous flowering. Cut flowers in early morning for arrangements. Maintain consistent watering.

5

Senescence/Dormancy Preparation

6-8 weeks

Late-season blooms become smaller and fewer. Foliage may yellow. Plant naturally slows growth as temperatures drop.

Reduce fertilizer by late summer. Stop deadheading by early fall to allow hips to form, signaling dormancy. Gradually reduce watering as temperatures cool.

Common Pests

  • Spray with water to dislodge; apply insecticidal soap or neem oil every 7 days. Increase humidity around plants.

  • Ensure excellent air circulation. Apply sulfur dust or baking soda spray (1 tbsp per gallon water). Remove affected foliage.

  • Remove infected leaves immediately. Apply fungicide containing chlorothalonil or sulfur. Water only at soil level.

  • Spray with strong water stream or insecticidal soap. Apply neem oil every 7-10 days if infestation persists.

Harvest Tips

Cut blooms in early morning when stems are fully hydrated, using sharp pruners at a 45-degree angle. Cut above a 5-leaflet leaf to encourage branching. Cut long stems (12+ inches) for arrangements. Crimson Glory flowers will continue to open and deepen in color after cutting. Remove lower leaves from cut flowers and change water every 2-3 days for 7-10 day vase life.

Fun Facts

  • 🌱 Crimson Glory was introduced in 1935 and won the Royal National Rose Society Gold Medal, establishing itself as one of the most fragrant Hybrid Tea roses ever bred.
  • 🌱 The deep crimson color intensifies as petals age, creating a dynamic color display where outer petals appear almost black-red while inner petals remain brilliant crimson.
  • 🌱 Crimson Glory is prone to 'split centers' where the bloom's center opens imperfectly, especially in extreme heat or after heavy rain—a characteristic so common it's become part of the variety's recognizable signature.
