WaterKorean Spice Viburnum should be watered thoroughly once a week, providing about 1 inch of water each time. During hot or dry periods, increase the frequency to twice per week, ensuring the soil is moist but not waterlogged. In the winter months, water less frequently, but do not allow the soil to become completely dry. Newly planted shrubs may require additional water to encourage root development; this can mean an additional 1 to 2 gallons per week depending on the size of the plant and weather conditions.
LightKorean Spice Viburnum thrives in conditions where it can receive full sun to partial shade. The ideal location is one where the plant is exposed to at least four to six hours of direct sunlight daily, accompanied by dappled or partial shade during the hottest part of the afternoon to protect it from intense sun exposure.
TemperatureKorean Spice Viburnum prefers temperate climates and can withstand a temperature range from 20°F to 75°F. However, the ideal temperature for optimal growth and blooming is between 60°F and 70°F. It is hardy in USDA zones 4 through 8, indicating it can survive winter temperatures as low as -30°F once established.
PruningPrune Korean Spice Viburnum after the flowers have faded in late spring to maintain its shape and encourage bushier growth. Remove any dead or damaged branches and trim up to one-third of the oldest stems to promote rejuvenation. The best time for pruning is immediately after the plant finishes blooming, typically in late spring or early summer.
CleaningAs needed
SoilKorean Spice Viburnum prefers well-draining soil with a high organic matter content. The best soil mix is one that combines two parts garden soil, one part peat moss or compost, and one part perlite or sand to ensure adequate drainage. The optimal soil pH for Korean Spice Viburnum should be slightly acidic to neutral, around 5.6 to 7.2.
RepottingKorean Spice Viburnum does not need frequent repotting as it's typically grown outdoors. When grown in containers, repotting may be required every 3-4 years or when the plant outgrows its current pot.
Humidity & MistingKorean Spice Viburnum thrives in average outdoor humidity levels. It is adaptable and does not have specific humidity requirements, but it benefits from the moist conditions in its natural outdoor environment.

Life cycleThe Korean spice viburnum ('Aurora' cultivar) begins its life as a seed, which after a period of dormancy, germinates in favorable conditions of warmth and moisture. Upon germination, the seedling emerges and, with proper soil, light, and water, develops a root system and foliage. As the plant matures, it forms a woody structure and produces distinctive fragrant pinkish-white spring blossoms that attract pollinators. After flowering, it enters the fruiting stage, developing red to blackish berries that are eaten by birds, aiding in seed dispersal. Throughout its life, the Korean spice viburnum experiences annual growth cycles, with foliage turning a vibrant red to purple in the fall before losing its leaves in winter. This deciduous shrub may live for many years, continuing its cycle of growth, flowering, and dormancy.
PropogationPropogation time
Spring to Summer
The most popular method of propagation for the Korean Spice Viburnum, Viburnum carlesii 'Aurora', is through semi-hardwood cuttings taken in late summer. To successfully propagate, select a healthy stem that is not too woody or too green and cut a 4-6 inch (10-15 cm) piece. The cutting should have at least two sets of leaves. Remove the leaves from the bottom half of the stem to prevent rotting when planted and dip the cut end into rooting hormone to encourage root development. Plant the cutting in a well-draining potting mix, ensuring that the leafless portion is buried. Keep the soil consistently moist and place the cutting in an area with indirect sunlight where it can maintain a temperature of about 65-75 degrees Fahrenheit (18-24 degrees Celsius). Roots will usually develop within a few weeks, after which the new plants can eventually be transplanted outdoors.
