Viburnum farreri is a loose, upright, rounded, deciduous viburnum that is native to mountainous areas of northern China. Typically matures in a compact rounded form to 10' (8-12') tall and as wide over time. Elliptic to oval heavily veined leaves (to 3" long) have toothed margins. Veins and petioles are reddish.
As for water requirements, they will need to be watered regularly while they’re getting established. It’s a good idea to use mulch to help the soil retain moisture.
Viburnum plants need a good amount of exposure to the sun in order to flower at their best. There are certain varieties that can cope in partial shade, but it’s usually better to pick a sunny spot.
Viburnum don’t require a specific type of soil to do well. Providing the soil is not overly saturated, they will be fine. If you want to use a fertiliser with your plants, then spring would be the best time.
Viburnum shrubs don’t need too much pruning, outside of removing dead leaves or damaged branches. If you notice that branches are becoming a little too dense, then it’s not a bad idea to prune them to improve air circulation. Good air circulation will mean your plants grow better and lessen the risk of disease.
When planting viburnum shrubs, you should pick a spot that gets plenty of sunlight. Some varieties are tolerant to partial shade, but in general viburnum are sun-loving plants. You should also make that the soil is well-drained.
