Growing White Viburnum

Viburnum Opulus

Viburnum opulus, also known as guelder rose or snowball tree, is a deciduous shrub that can reach heights of 10-12 feet (3-3.7m). This variety of white viburnum prefers full sun or partial shade and requires well-draining soil that is moist but not waterlogged. It's important to ensure that the soil is rich in nutrients and has a slightly acidic pH level.

Soil Requirements

White viburnum thrives in soil that is nutrient-rich and slightly acidic, with a pH between 5.5 and 6.5. It's important to avoid soil that is poorly drained, as this can result in root rot and other issues. Adding organic matter, such as compost or aged manure, to the soil can help improve its quality.

Sunlight Needs

The white viburnum is a versatile plant that can adapt to different light conditions. It prefers partial shade to full sun exposure, so it's important to provide it with at least six hours of sunlight per day.

Watering Instructions

White viburnum prefers soil that is moist but not excessively wet. It's best to water deeply once a week during periods of low rainfall, especially during hot weather. Always check the soil moisture level before watering to avoid overwatering, which can lead to root rot.

Fertilization Tips

While white viburnum does not require heavy fertilization, it's recommended to apply a slow-release fertilizer once every season to help promote healthy plant growth. Using a balanced fertilizer with a ratio of 10-10-10 works well on this shrub.

Pruning your white viburnum shrub is essential to keep it healthy and strong. It's best to prune after the shrub has finished blooming in the spring. Remove any dead or diseased branches, as well as any crossing branches that rub against each other. Prune to maintain the desired shape and size of the shrub.

Pest and Disease Control

While white viburnum is generally a hardy shrub, it can fall prey to pest infestations such as aphids, spider mites, and scale insects.
