When Is The Best Time To Trim A Snowball Bush?

Q: When is the best time of year to trim a snowball bush? My bush is ten feet tall and I want it shorter. 

A: The best time to prune snowball bush, Viburnum macrocephalum, is after it finishes blooming and the white flowers have turned to brown. Keep in mind that this shrub is naturally quite large. To keep it small, you’ll have to prune it every year after flowering.
