Dormancy & Spring Emergence
4-6 weeksCanes 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.
Vegetative Growth
6-8 weeksLeafy 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.
Budding
2-3 weeksTight 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.
Flowering
3-5 days per bloom; repeat cycles until fall frostBlooms 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.
Fall Decline & Winter Dormancy
8-12 weeksBlooming 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.

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.
