Siebold viburnum

Siebold viburnum should be watered regularly during the growing season, typically during the months of April to September. This plant species typically needs to be watered once per week during the summer months. However, if the climate is particularly dry during the summer months, additional watering may be necessary. To water Siebold viburnum, use a soaker hose or drip irrigation system to apply water slowly at the soil surface. If you are using a sprinkler, water the plant until the top 6 inches of soil become moist. During periods of rain and cooler temperatures, however, there is no need to water the plant.

Siebold viburnum (Viburnum sieboldii) prefers light to full sun, but it can tolerate part shade. For the majority of the day, it should receive at least 4 hours of direct sunlight. In the summer, when the days are long, try to provide 8 to 10 hours of sun. If planted in an area with part shade, a few extra hours of indirect light should make up the difference. To ensure your viburnum thrives, avoid full shade, especially in the midday sun.

Pruning your Siebold viburnum (Viburnum sieboldii) should take place in late winter or early spring before new growth appears. Start by removing any dead or damaged branches, then cut back any vigorous branches to open the centre of the plant and thin out any overcrowding. Reduce the overall size of the plant by cutting back 1-third of the longest branches to the desired shape. To maintain a neat and tidy form, regularly prune any wayward branches. Avoid over-pruning as this can weaken the plant and reduce flowering in subsequent years.
