If you're looking for an easy-maintenance, landscape shrub with year-round appeal, viburnums are a good choice. Viburnums display interesting horizontal and tangling branches in the winter, white flowers in the spring, red berries in late summer and purple leaves in the fall. They have few natural diseases and pests and aren't invasive. Hundreds of varieties exist, but according to the University of Connecticut, Shasta viburnum remains one of the best and most popular varieties. Shasta viburnum has an appealing rounded shape and is best left largely unpruned. Prune minimally in early spring when necessary.
Prune out diseased or dead branches. Use a pruning saw for branches over 1 inch and pruning shears for smaller branches.
Prune branches that are rubbing against each other.
Cut back suckers at the ground if the base of the plant is becoming thick and crowded.
