🌿 Care Guide
Watering
Moderate watering required; keep soil consistently moist but well-drained, typically watering deeply once a week during the growing season.
Fertilizer
Apply a balanced rose fertilizer in early spring and again in mid-summer to support growth and health.
Pruning
Prune in late winter or early spring before new growth begins to remove dead or diseased wood and maintain shape; since it is once-blooming, major pruning should occur after the flowering season.
Pests & Diseases
Susceptible to common rose issues such as aphids, spider mites, black spot, and powdery mildew.
