Establishment
4-6 weeksNew rose bush with developing root system and initial leafy growth
Water deeply and regularly. Apply mulch around base (2-3 inches, keeping away from stem). Avoid heavy pruning first year; remove dead canes and crossing branches only.
Vegetative Growth
8-12 weeks (spring through early summer)Vigorous cane development with healthy dark green foliage and multiple stems emerging
Continue consistent watering and fertilizing every 2-3 weeks. Monitor for pests and diseases. Light deadheading encourages branching.
Budding & Flowering
3-4 weeks per bloom cycle; repeats throughout seasonHigh-centered red buds forming and opening into full, fragrant blooms on long stems
Deadhead spent flowers just above the first 5-leaflet leaf to encourage reblooming. Continue fertilizing. Provide afternoon shade in hot climates (over 90°F) to preserve color.
Flush Blooming
Continuous with proper care, spring through frostMultiple waves of flowers produced in succession, especially after pruning or deadheading
Maintain regular watering and feeding schedule. Remove any diseased foliage promptly. Deadhead consistently.
Winter Dormancy
8-12 weeks (October/November through February/March)Slowed growth and leaf drop as temperatures cool in late fall and winter
Reduce watering significantly. In zones 5-7, apply 4-6 inches of mulch around base for protection. In zone 9+, light pruning of thin/dead canes may be done. Stop fertilizing 6-8 weeks before first frost.

Harvest Tips
Cut blooms in early morning when buds are just opening for longest vase life (7-10 days). Cut stems at a 45-degree angle just above an outward-facing 5-leaflet leaf. Remove lower leaves that would sit below the water line. Recut stems and change water every 2-3 days. For continued plant blooming, deadhead faded flowers regularly by cutting back to the first healthy 5-leaflet leaf.
