Establishment
4-6 weeksNewly planted rose with early leaf growth and initial root development
Water regularly to establish roots. Avoid heavy fertilizing first season. Remove spent blooms to encourage growth rather than seed production.
Vegetative Growth
6-8 weeksStrong stem and foliage development with multiple canes growing upright to 3-4 feet tall
Prune lightly to shape plant and encourage bushiness. Begin light fertilizing with balanced rose fertilizer every 4-6 weeks in growing season.
First Bloom Cycle
4-6 weeksInitial flower buds forming on new growth, developing full quartered blooms in soft pink
Deadhead spent flowers just above the first 5-leaflet leaf to promote continuous blooming. Provide adequate water during bloom.
Repeat Blooming
12-16 weeksSuccessive flushes of blooms throughout summer and fall on mature plants
Continue deadheading and regular watering. Apply balanced fertilizer every 4 weeks through August. Watch for pests and diseases.
Dormancy
8-12 weeksSlowing growth in fall and winter, some leaf drop in colder zones
Stop fertilizing in August to harden off plant. Prune in early spring after last frost. Mulch to protect roots in zones 5-6.
