Q&As/Flowering Shrubs and Trees/Viburnum
Our viburnum (not a snowball one), has grown very straggly and back in May, half of it was blooming, and the other half was leafless. Would it be wise to cut it back, and if so, by how much?
With flowering shrubs, there is a general rule that you prune immediately after flowering has finished. This allows sufficient time for flower buds to develop for next season’s flowering.
Some viburnum have varying amounts of dead branches and twigs as part of their natural growth. These can be removed to allow room for flowering wood to develop.
All viburnums grow best in a soil rich in organic matter, therefore spread Daltons 7in1 Boosted Compost around the base of the shrub throughout the growing season and feed with Daltons Premium Tree & Shrub Fertiliser. A light pruning in summer may be required when branches appear growing at unusual angles or where not required.
