Where & when to plant Viburnum Plicatum
The best time to plant Viburnum plicatum is in the autumn, to allow the roots to develop prior to the winter frosts. As a tall shrub, it is best placed at the back of a garden border. You can also grow Viburnum plicatum in containers, mixed containers and pots.
How to plant Viburnum Plicatum
- Start by choosing a border, pot or container in a position that benefits from 2-4 hours of sunlight a day to plant your Viburnum plicatum in. Ideally, this position will benefit from morning sun and evening sun, rather than the stronger midday sun
- Once you have found your position, make sure that the soil is well-draining. If your soil is not, you can add sand or gravel to create drainage
- Dig a hole that’s 2-3 times as wide and deep as the roots. Add your root ball to the soil and backfill with the soil removed. Tamp the soil around the plant and settle in by watering
- If you are planting multiple Viburnum plicatum or neighbouring plants, give 1m of space between each to allow their roots and top growth to spread. While your Viburnum plicatum is establishing, water 2-3 times per week.
What to plant with Viburnum Plicatum
Grow Viburnum plicatum with smaller plants that bloom in the spring and summer. If growing your Viburnum plicatum at the back of a border, choose neighbouring plants that are shorter that enjoy similar soil and bloom in the same period. Black-eyed Susan (Rudbeckia) is one such choice that blossoms in late summer, adding sunflower-style interest to any garden border. Due to the ornamental nature of Viburnum plicatum, you could create an oriental-inspired bed with pink spring-bloomers such as rhodedendrons or pair with other viburnums such as Viburnum opulus.

How to care for Viburnum Plicatum
Pruning & Deadheading
Viburnums flower on old wood, so do not prune too late in the year as you might ruin the following year’s growth - autumn is also a good time to shape the plant. As always, remove any dead, damaged or diseased stems as you see them. Viburnum plicatum tolerates hard renovative pruning in the spring, however, it is important not to hard prune the plant until it is established.
Watering
Viburnum plicatum should be watered regularly during its growth phase - this means 2-3 times per week. Once established, Viburnum plicatum is fully hardy and can tolerate moderate watering. Be sure to keep an eye on the soil for drainage.
Cold Protection
As a fully hardy shrub, Viburnum plicatum can tolerate temperatures as low as -15°C. Choose a position for Viburnum plicatum with shelter from cold and harsh winds if you are concerned.
Pests & Diseases
While there are no serious pests or diseases to look out for with Viburnum plicatum, its love for moist, well-draining soil may cause issues. If your soil has a lack of drainage or the plant is overwatered, Viburnum plicatum may suffer from root rot; this is a disease where oxygen cannot reach the roots of a plant, so be mindful.
How to propagate Viburnum Plicatum
Propagate your Viburnum plicatum plant during spring by taking softwood cuttings. Use clean scissors or secateurs to make sure you do not pass diseases on from other plants to your new cuttings
From healthy softwood shoots, trim 10-15cm of length off. A good tip is to add the end of the cuttings directly to a small pot of water to reduce moisture loss
Once you have finished taking your cuttings, remove the leaves from the lower 3-5cm of each stem, leaving a small bit of leaf joint intact. Before planting in a pot of cutting soil, trim the bottom of each cutting diagonally and add each to a corner of your pot to help keep your cuttings upright during growth then water in to settle
Add a plastic covering or cloche to your cuttings pot to encourage humidity. Place your pot of cuttings in a sunny and warm position out of direct sunlight. Water regularly to keep the soil moist and check for roots after 3 weeks by gently pulling on each cutting.
