Establishment
4-8 weeksYoung shrub with initial root and shoot development, sparse foliage
Water regularly to establish roots. Mulch 2-3 inches around base. Avoid heavy pruning first year. Provide shelter from harsh winds.
Vegetative Growth
Spring through early summer, 8-12 weeksStrong cane development with dense, disease-resistant foliage. Shrub expands rapidly with vigorous upright growth
Maintain consistent watering. Apply balanced fertilizer monthly during growing season. Remove any diseased canes. Shape plant as desired through light pruning.
Flowering
Late spring through frost, 16-20 weeksAbundant clusters of deeply cupped, intensely fragrant magenta-purple flowers. Blooms are prolific and continuously produced
Deadhead spent blooms to encourage continuous flowering, though hips are ornamental if left. Apply rose fertilizer every 4-6 weeks. Provide afternoon shade in hot climates.
Hip Formation & Autumn
Late summer through fall, 8-12 weeksLarge, wrinkled bright red hips develop where flowers were. Foliage may yellow and drop. Plant prepares for dormancy
Stop deadheading to allow hip development for ornamental value. Reduce nitrogen fertilizer. Continue watering until ground freezes. Leave hips on plant for wildlife and winter interest.
Winter Dormancy
November through MarchCanes bare or with minimal foliage. Plant is fully dormant and cold-hardy
Prune in late winter before growth begins, removing dead wood and crossing canes. Can cut back to 18-24 inches for renewal. Apply dormant oil spray if needed. Mulch for insulation in severe climates.
