Establishment
4-6 weeksNew plant with initial shoots and leaf development; root system establishing in soil
Keep soil consistently moist but not waterlogged. Provide shelter from strong winds. Avoid fertilizing first month to prevent tender new growth. Prune out any dead canes.
Vegetative Growth
Spring through early summerVigorous cane and foliage development; plant reaches full structural size with healthy green shoots
Apply balanced fertilizer (NPK 10-10-10) or rose-specific formula every 4-6 weeks. Mulch with 2-3 inches of organic material. Monitor for pests and disease. Prune lightly to shape.
First Blooming
6-8 weeksFlower buds form along canes; first blooms appear in apricot-orange tones, opening to quartered form
Deadhead spent blooms to encourage repeat flowering. Increase potassium fertilizer (e.g., rose food) to support blooming. Ensure consistent watering during this energy-intensive stage.
Repeat Blooming
Mid-summer through fall frostContinuous cycle of flowering through season; flowers deepen in color (amber to russet) as they age; clusters of up to 5-7 blooms per stem
Continue deadheading for continuous bloom. Fertilize every 4 weeks through August. Watch for powdery mildew in humid conditions; ensure good air circulation. Reduce feeding after late August.
Dormancy
Late fall through early springGrowth slows as temperatures drop; foliage may discolor; plant prepares for winter rest
Stop fertilizing by late August/early September. Reduce watering. Do not prune in fall (promotes tender growth). In cold zones, mound soil or mulch around base after first frost. Leave seed hips on plant for winter interest.

Harvest Tips
Cut flowers in early morning when dew has dried and blooms are freshly opened. Use sharp, clean bypass pruners. Cut stems at 45-degree angle above outward-facing 5-leaflet leaf. Remove lower leaves below the waterline. For longest vase life, change water every 2-3 days and re-cut stems. Deadhead spent blooms (cut back to first 5-leaflet leaf) to encourage more flowering throughout the season.
