Water regularly and consistently. Avoid fertilizing the first 4-6 weeks. Mulch around base but keep 2-3 inches away from canes. Monitor for transplant shock.
Vegetative Growth
6-8 weeksPlant produces multiple canes and abundant foliage. New shoots emerge from the base and lateral buds on existing canes.

Flowering
6-12 weeks per flush (repeat blooming throughout season)Large, deep crimson buds form at the end of canes and unfold into full, velvety blooms. Flowers are typically solitary or in small clusters.
Deadhead spent flowers to encourage continuous blooming. Support heavy flower stems if needed. Increase watering during bloom season. Enjoy the classic fragrance.
Mid-Season Decline
4-6 weeksBlooming slows in peak summer heat. Plant may appear stressed with fewer flowers.
Reduce fertilizing. Prune lightly to prepare for fall flush. Increase watering and provide afternoon shade in very hot climates.
Fall & Dormancy
8-12 weeksPlant enters dormancy as days shorten. Growth slows, leaves may change color. In cold climates, prepare for winter hardening.
