🌿 Care Guide
Watering
Regular watering; prefers well-draining soil and can benefit from planting on a slight mound in heavier soils.
Fertilizer
Feed in early spring (March or April) as growth begins and again in mid-summer after the first flush of flowers. Use a balanced rose fertilizer. Stop all fertilization by mid-August to prevent soft new growth that could be damaged by winter frost.
Pruning
Regular but uncomplicated pruning and deadheading are recommended to encourage repeat blooming.
Pests & Diseases
Good resistance to common rose diseases like powdery mildew and black spot.
