Ninebark Physocarpus opulifolius Angel Gold = 'Minange' (PBR)

Water

Ninebark should be watered deeply once a week, allowing soil to dry out slightly between waterings. During hot, dry periods, you may need to water twice a week, especially in the first growing season to establish a deep, extensive root system. When watering, apply about 1 to 1.5 gallons of water per plant, focusing on the root zone. It's important to avoid overhead watering to prevent fungal diseases, so direct the water at the base of the plant. During winter, reduce watering frequency, as the plant requires less moisture due to slower growth.

Light

Ninebark prefers full sun but can tolerate partial shade. The ideal spot for this plant would provide at least six hours of direct sunlight each day. Too little light can result in fewer flowers and a less vibrant foliage color. If you are planting it in a garden, make sure it is in a position where it can receive ample sunlight throughout the day for optimal growth and coloration.

Temperature

Ninebark thrives in a wide range of temperatures, handling a maximum around 100°F and can survive winter temperatures as low as -20°F. It performs best in moderate climates where temperatures are typically between 60°F and 85°F. This shrub is quite hardy and adaptable to various temperature conditions, making it an excellent choice for many gardens.

Pruning

Ninebark should be pruned to maintain shape and encourage vigorous growth. Prune in late winter or early spring before new growth starts. Remove any dead or damaged branches, and thin out the center of the plant to improve air circulation. Every few years, consider rejuvenating the plant by cutting it back to about two feet above ground level to promote fresh growth. The best time for more extensive pruning is after the plant has flowered if you wish to shape it or maintain a particular size.

Cleaning

As needed

Soil

Ninebark 'Angel Gold' prefers well-drained soil with a pH range of 5.5 to 7.0. A good soil mix would include loamy soil, compost, and a small amount of sand to improve drainage. Amending the soil with organic matter will provide nutrients and help retain moisture while still allowing excess water to escape, ensuring the roots do not become waterlogged.

Repotting

Ninebark 'Angel Gold' does not typically require frequent repotting as it is a shrub meant for outdoor growth. It may only need repotting or transplanting if it outgrows its space or when initially planting the shrub in the landscape. Once established, repotting is rarely necessary unless renewal of the soil or division of the plant is desired.

Humidity & Misting

Ninebark 'Angel Gold' is adaptable to a wide range of humidity conditions and does not require any specific humidity level to thrive. As a hardy shrub, it can tolerate the naturally occurring humidity in most outdoor environments where it is suitable to be grown.

Suitable locations

Life cycle

Physocarpus opulifolius Angel Gold, commonly known as Ninebark 'Angel Gold' begins its life cycle as a seed, germinating when conditions of temperature and moisture are right. Upon sprouting, it develops a root system and produces its first set of true leaves, entering the vegetative stage where it focuses on growth. As a deciduous shrub, it undergoes an annual cycle of leafing out in the spring, followed by rapid vegetative growth and then blossoming in early summer with clusters of small, white or pink flowers. After pollination, the flowers develop into small red fruits (follicles) by late summer, which mature and release seeds for dispersal. In the fall, the shrub's leaves turn colorful shades before being shed as it enters dormancy for the winter. Lastly, with the return of favorable conditions in the spring, the plant breaks dormancy and begins a new growth cycle.

  Spring-Early Summer

• The most popular method for propagating Ninebark 'Angel Gold' ('Minange') is through softwood cuttings. This is typically done in late spring or early summer when new growth is still supple. To undertake this propagation method, one would cut a stem from a healthy parent plant, making sure the cutting is approximately 4-6 inches (10-15 cm) long with several leaf nodes. The leaves on the lower half are removed, and the cut end may be dipped in rooting hormone to encourage root development. The cutting should then be inserted into a well-draining soil mix, ensuring that at least two leaf nodes are buried. The cutting needs to be kept moist and in a warm environment with indirect sunlight until roots have developed, which usually takes a few weeks. After root establishment, the new Ninebark plant can be gradually acclimated to outdoor conditions before being planted out in its permanent location.
