The best way to Grow Ninebark
Notable because of its layers of peeling bark, ninebark (Physocarpus spp.) makes an excellent specimen in several places of the backyard. It grows as it does in sunlight and tolerates poor soil problems including clay and sand. Following its colourful spring and summer flowers, ninebark bears vivid, attractive berries in the fall. Some types have red to purplish foliage that improve the landscape. With respect to the species, ninebark is developed in Sunsetâs Environment Zones 110, 1419 and 3245.
Grow ninebark in moist, well-drained soil. Ninebark prefers moist conditions, including near a stream though it tolerates most soil types.
Water ninebark often throughout the growing period to sustain moist soil problems, particularly the first-year. In subsequent years, dry conditions can be tolerated by ninebark. Irrigate seriously with about 1-inch of water.
When the leaf buds swell with new development fertilize ninebark in the spring. Use an all purpose fertilizer and use the amount suggested on the label. Spread the fertilizer below the canopy of the plant, then water it in.
Prune ninebark after it flowers in early summer or late spring. Prune to eliminate outdated, woody development also to shape. Cut branches back to just above a leaf established or to the floor. To sustain a flourishing, shrub that is flowering, prune only one-third of the bush in 12 months.
Rejuvenate an unproductive or over-grown ninebark by reducing it back to the floor in the cold temperatures. It’s going to have a couple years for this to grow back right into a full size shrub.
