🌿 Care Guide
Watering
Keep soil evenly moist during establishment; mature plants require approximately 1 inch of water per week, ideally applied at the base.
Fertilizer
Use a balanced fertilizer or one formulated for roses. Begin feeding in spring after pruning and new leaves appear, and repeat after each major flush of blooms.
Pruning
Prune in late winter or early spring before new growth begins. For shrub roses, remove dead or diseased canes and shape for airflow; avoid cutting back more than 1/3 of the outside growth.
Pests & Diseases
Common issues include aphids, black spot, powdery mildew, Japanese beetles, mites, thrips, caterpillars, scale, nematodes, rose chafer, rust, verticillium wilt, rose mosaic, crown gall rot, and rose rosette disease.
