2-3 monthsYoung plant develops root system and establishes baseline growth structure
Water regularly to establish roots. Avoid heavy pruning first year. Apply mulch around base, keeping it 2-3 inches away from the cane.
Vegetative Growth
3-4 monthsPlant produces new canes and foliage, building a compact, bushy framework
Prune lightly to shape and remove dead/diseased wood. Feed with balanced fertilizer every 4-6 weeks during growing season.
Budding
2-3 weeksFlower buds form at branch tips; buds are distinctly visible and begin to swell with color showing at the sepals
Continue regular watering and fertilizing. Pinch back any crossing or weak canes. Watch for aphids and spider mites.
Flowering
4-6 weeks per flush; continuous from spring through fallQuartered pink blooms open in waves; flowers are fragrant and medium-sized, appearing continuously through growing season
Deadhead spent flowers to encourage reblooming. Water consistently. Reduce nitrogen fertilizer to promote flowering over vegetative growth.
Winter Dormancy
2-3 monthsIn colder zones (7-8), plant enters dormancy with reduced growth and minimal flowers; in warm zones, flowering continues at reduced pace

Harvest Tips
Cut flowers when outer petals just begin to unfurl for longest vase life (7-10 days). Cut in early morning when stems are hydrated. Make cuts at a 45-degree angle just above an outward-facing leaf node with 5 leaflets. Remove lower leaves below the waterline in the vase.
