Establishment
4-8 weeksYoung plant develops root system and produces initial growth shoots. Leaves emerge pale green and may appear sparse.
Water regularly to establish roots. Avoid heavy pruning. Remove any early flower buds to redirect energy to growth. Apply mulch around base.
Vegetative Growth
6-12 weeksPlant develops strong canes with healthy dark green foliage. Vigorous shoot growth occurs; plant reaches mature height and width.
Prune to shape and remove weak or crossing canes. Fertilize every 4-6 weeks with rose fertilizer. Monitor for pests and diseases.
Flowering
4-6 weeks per flush; repeats throughout growing seasonLarge, deep red, velvety blooms with classic high-centered form appear on long stems. Strong fragrance is evident. First flush followed by repeat blooms.
Deadhead spent flowers to encourage continued blooming. Water deeply at soil level. Apply rose fertilizer to support bloom production. Cut flowers for arrangements.
Dormancy Preparation
6-8 weeks in fallIn fall, growth slows and flower production decreases. Foliage may show color changes. Plant prepares for winter rest.
Reduce watering and fertilizing. Stop deadheading 6 weeks before first frost to allow hips to form and signal dormancy. Clean up fallen leaves to prevent disease.
Winter Dormancy
2-4 months depending on zonePlant goes dormant; foliage drops in cold climates. Canes harden off for winter protection.
In zones 5-6, mound soil or mulch 10-12 inches around base for winter protection. Prune in late winter/early spring. No watering or fertilizing needed.

Harvest Tips
Cut flowers in early morning when stems are fully hydrated but before heat of day. Flowers should be just opening to maintain vase life of 7-10 days. Cut at 45-degree angle just above an outward-facing 5-leaflet leaf. Remove lower foliage and place immediately in cool water with flower food. Deadhead spent blooms throughout season by cutting above first 5-leaflet leaf to encourage more flowers.
Fun Facts
- 🌱 Rosa Sieger was bred in Germany and named to mean 'Rose Winner,' reflecting its award-winning status in horticulture and its success in international rose competitions.
- 🌱 The velvety texture of the deep red petals comes from specialized pigment cells and petal structure that create a soft, luxurious appearance and intensify the color saturation.
- 🌱 Rosa Sieger is highly fragrant due to volatile organic compounds including compounds like geraniol, linalool, and benzyl acetate—the same compounds found in fine perfumery.
