How to grow viburnum
Whilst most viburnums are hardy and resilient, it is important to follow some basic principles when planting and maintaining. Read our top tips on how to care for viburnum to ensure that your shrub succeeds.
Considerations when growing viburnum
The viburnum genus has a global distribution, and can be found in North America, Europe, Asia, and Africa. Needless to say, this wide range of different species and varieties will all have different growing preferences. 'With such a diverse range of viburnum varieties available, it's important to choose the one that suits your specific growing conditions and preferences,' says Alex Kantor, gardening expert and owner at Perfect Plants.
When considering if you can grow viburnum in your garden, note that most varieties will grow in US hardiness zones 2 – 8 but it is always worth reading the plant label to make sure the variety is suitable for you. 'Viburnum varieties offer a wide range of choices for gardeners, each with its own unique characteristics,' Alex continues.
The spring flowering Viburnum carlesii, for example, will thrive in zones 4 – 8, but will not enjoy the cooler conditions of zones 2 and 3. In addition, the popular Viburnum tinus will do well growing in the warmer zones 8, 9 and 10. A useful and popular option to consider that is readily available to purchase, such as this Viburnum Tinus 'Compactum' or commonly known as the Spring Flowering Viburnum from My Perfect Plants.
Finally, it is important to find the right place in your backyard for your viburnum. Many gardening experts consider viburnum to be an easy option, and whilst this is true, it is important to remember that they need space to grow. 'Certain varieties can grow quickly, reaching their mature height and spreading within a few years, like the sweet viburnum,' Alex says. Always select a location where you can get the most out of your plant, and you are not regularly cutting it down.

Top Tips For Planting And Maintaining Viburnum
- Soil: The best time to plant viburnums 'is in the spring or fall when the soil is workable,' Alex recommends. They 'prefer moist, but well-drained soil.' You can add some form of soil improvement or drainage material at the base before planting, and yearly mulching will help improve the quality of your soil.
- Light: For the best results, follow specific preferences of your viburnum variety, but generally they will do well in a location 'ranging from full sun to partial shade,' Alex says. Whilst many consider viburnum an option for a shady backyard, this is not the case, growing better in lighter positions.
- Watering: 'Regular watering is important, especially during dry periods, to ensure healthy growth,' Alex says. 'Be sure not to overwater your plant. Viburnums do not do well with soggy or consistently wet soil.' Once established, many varieties will survive dry periods just fine, with little attention.
- Fertilizing: Most viburnums do not need fertilizer once established. However, during the first year, you can apply a general feed to encourage healthy growth of foliage, flowers and root system.
- Pruning: Whilst most viburnums are easy to grow, 'most will require some maintenance, involving some pruning to remove dead or diseased branches,' Alex says. Knowing when to prune viburnums is important, but this is usually after flowering has finished. At this time, you can shape your shrub, and remove damaged and diseased wood.
