ninebark

Ninebark (Physocarpus opulifolius 'Center Glow') should be watered deeply every 2 to 3 weeks during its first growing season. Water until the soil is wet but not soggy, and reduce the frequency in the late summer/early fall months. Once established, ninebark should be watered every 7 to 10 days; more frequent watering may be needed during hot, dry spells. During colder winter months, water only when the soil begins to dry out.

Ninebark (Physocarpus opulifolius 'Center Glow') is an attractive, deciduous flowering shrub with bright gold or orange foliage. The plant grows best in full sun and prefers 6 to 8 hours of direct sunlight each day. It can also tolerate some shade, but too much shaded will reduce the plant's flowering potential. During the summer months, when the weather is warmer and the days are longer, ninebark will benefit from as much direct sunlight as possible. In winter, however, when temperatures drop and days are shorter, ninebark can tolerate some afternoon shade, but it is still best to provide at least 6 hours of direct sunlight each day.

Ninebark should be pruned to maintain its desired shape and size. Prune in late winter or early spring when the plant is dormant. This plant can tolerate hard pruning when needed. Remove any dead or damaged branches. Thin the plant out by removing overcrowded or crossing branches. This will help promote air circulation which will help reduce the chance of disease. Prune out any suckers you may see (shoots that grow near the base of the plant). Remove any branches that are too large for the desired shape. When finished, maintain the shape by occasionally pruning any new growth.
