Growth Stages

1

Dormancy & Spring Emergence

4-6 weeks

Canes are bare or have minimal foliage; new red growth begins emerging from buds in spring

Perform late-winter/early-spring pruning to remove dead wood and shape plant. Cut at 45° angles above outward-facing buds. Apply dormant oil spray if needed. Begin feeding when growth starts.

2

Vegetative Growth

6-8 weeks

Leafy canes develop rapidly with compound leaves and thorns; plant reaches full size with deep green foliage

Remove any dead or diseased canes. Deadhead any early small flowers to encourage strong plant establishment. Monitor for pests and diseases. Provide consistent water and fertilizer every 4-6 weeks.

3

Budding

2-3 weeks

Tight flower buds form at cane tips, gradually enlarging and changing color from green to pink-tinged white

Reduce nitrogen fertilizer; switch to bloom-promoting fertilizer high in phosphorus. Ensure consistent moisture. Remove any damaged or diseased buds. Do not handle buds excessively.

4

Flowering

3-5 days per bloom; repeat cycles until fall frost

Blooms open to reveal classic hybrid tea form with high-centered white petals, cream undertones, and delicate fragrance

Deadhead spent flowers just above the first 5-leaflet leaf to encourage repeat blooming. Provide steady moisture and balanced fertilizer every 4-6 weeks. Spray preventatively for powdery mildew if needed.

5

Fall Decline & Winter Dormancy

8-12 weeks

Blooming slows, foliage may yellow, canes harden off and become woody for winter

Reduce watering and feeding in late fall. Stop fertilizing 6-8 weeks before first frost to avoid tender new growth. In cold climates, mound soil 10-12 inches around base or apply winter protection mulch. Prune back dead canes in spring.

Common Pests

  • Spray with strong water jet, apply insecticidal soap, or use neem oil. Encourage beneficial insects like ladybugs.

  • Hand-pick early morning, apply rose-specific beetle traps away from plant, or use neem oil. Avoid systemic insecticides that harm pollinators.

  • Increase humidity by misting foliage, spray with miticide or neem oil, improve air circulation.

  • Improve air circulation, avoid overhead watering, apply sulfur powder or fungicide, remove infected leaves.

  • Remove infected leaves immediately, improve drainage and air flow, apply fungicide, water only at soil level.

Harvest Tips

Cut blooms in early morning when stems are fully hydrated but buds haven't fully opened. Use sharp pruning shears at a 45° angle just above a 5-leaflet leaf. Immediately place cut stems in cool water with floral preservative. For maximum vase life, remove lower leaves, recut stems every 2-3 days, and keep in cool location away from ripening fruit and direct sun.

Fun Facts

  • 🌱 White Charm is a hybrid tea rose, a class that was developed in the late 19th century by crossing hybrid perpetuals with tea roses, resulting in large, fragrant blooms with longer stems than most other rose types.
  • 🌱 The pristine white color in roses comes from the absence of pigments like anthocyanins and carotenoids; while it appears pure white, White Charm actually has subtle cream undertones that develop with age.
  • 🌱 Roses have been cultivated for over 5,000 years and are one of the most extensively bred ornamental plants in the world, with over 30,000 registered cultivars, making them the most diverse flowering plant in horticulture.
