🌿 Care Guide
Watering
Provide regular watering during the first growing season to establish the root system; once established, it is relatively drought-tolerant.
Fertilizer
Apply a balanced fertilizer in early spring before the growth begins. Additional organic mulching is beneficial.
Pruning
As a once-blooming rose, prune only after the flowering period has finished in mid-summer. Thin out old canes and remove dead wood to maintain shape.
Pests & Diseases
Generally exhibits high resistance to blackspot, though it may be susceptible to powdery mildew in poor air-circulation conditions.
