🌿 Care Guide

Watering

Regular watering is required; ensure the soil remains moist but well-drained. Avoid overhead watering to reduce the risk of foliage diseases.

Fertilizer

Apply a balanced rose fertilizer in early spring and repeat after the first flush of blooms to support continuous flowering throughout the season.

Pruning

Prune in late winter or early spring before new growth begins. Remove dead, diseased, or thin wood and cut back healthy canes by about one-third to encourage vigorous new growth.

Pests & Diseases

Generally healthy and disease-resistant, though it may occasionally be susceptible to black spot or powdery mildew in humid, poorly ventilated conditions.
