Establishment
12 monthsFirst year after planting; shoots emerge and foliage develops slowly
Keep consistently moist but not waterlogged. Apply 2-3 inches of mulch. Don't expect significant flowering in year one.
Vegetative Growth
Spring, 6-8 weeksVigorous cane growth in spring; dense foliage develops on long, arching branches
Prune lightly in early spring to shape. Allow natural spreading habit. Fertilize monthly during growing season with rose fertilizer.
Pre-flowering
Late spring, 3-4 weeksFlower buds form along canes; plant becomes heavy with developing bloom clusters
Continue regular watering. Avoid heavy fertilizing with nitrogen to encourage blooms. Ensure adequate potassium and phosphorus.
Flowering
Early to mid-summer, 4-6 weeksAbundant single pink flowers (2-3 inches) with white eyes bloom along entire length of canes; fragrant and bee-attractive
Deadhead spent flowers to encourage repeat cycles (though primarily once-blooming). Enjoy peak bloom over 3-4 weeks. Water regularly.
Post-bloom & Dormancy
Summer through winterFlowers fade; hips develop if left on plant; foliage remains healthy throughout summer; plant hardens off in fall
Stop deadheading to allow hip formation, which adds winter interest and feeds wildlife. Reduce watering in fall. No pruning needed in fall; prune only in early spring.
