Ninebarks is a hardy plant genus requiring medium-light conditions, well-drained soil, and moderate water. Ideal temperatures range from 60–85°F. Major challenges include powdery mildew, aphids, and scale insects. In summer, extra watering is needed due to increased evaporation. In winter, a decrease in watering and a layer of mulch can help protect the root system. Regular pruning in late winter or early spring is recommended for healthier growth. Come autumn, no special considerations besides regular watering and check for pests.
