watering

Ninebark plants need to be watered regularly. Most prefer a consistently moist soil, so water your ninebark twice weekly, or whenever the soil feels dry to the touch about 1 inch below the surface. During especially hot and sunny periods, lightly water the plant 3 times a week. During the winter months water less often, about once a week, as the plant goes dormant. Make sure not to over water the plant as it can lead to root rot. If your climate receives regular rain water, then you may not need to water. In that case, check to make sure the soil still feels damp and adjust your watering accordingly.

sunlight

Ninebark (Physocarpus opulifolius 'N5' PANTHER) thrives best in full sun, meaning at least 6 hours of direct sunlight per day. Though the plant will tolerate partial shade, it may become leggy and have fewer flowers in less sun. If possible, make sure the ninebark receives midday sun, as a few hours of morning and a few hours of afternoon sun is usually not enough to promote strong growth and flowering. If your ninebark is planted in an area with less than 6 hours of direct sun, supplementing with grow lights planted nearby may be recommended.

pruning

Ninebark (Physocarpus opulifolius ‘N5’ PANTHER) should be pruned in the spring, just as new growth begins to emerge. Pruning should consist of selectively removing any dead, diseased, or damaged stems, as well as any stems that are overcrowded. Remove up to 1-third of the total stems each year for optimal shape and air flow, being sure to make the cuts near the base of the stem. The remaining stems should be pruned back to an outward-facing bud. Regular pruning will encourage new foliage growth and prevent any encroachment onto nearby plants.
