Mallow Ninebark is easy to establish and care for, making it a great choice for natural hedges, wildlife plantings, and stabilizing slopes. Plant in fall or early spring in full sun to light shade, in well-drained soils ranging from sandy to loamy. Once established, it is highly drought-tolerant and requires little watering. Mulch during establishment to conserve moisture and suppress weeds, but avoid piling mulch against the stems. This shrub spreads by suckering, forming dense thickets that provide excellent cover and erosion control, though thinning may be needed in smaller spaces. Light pruning in late winter or early spring can help manage shape, but heavy pruning should be avoided during nesting season to protect wildlife.
