Some of our viburnums didn't flower this spring. Did we prune at the wrong time and cut off the future flowers? They were pruned in June and late summer.

If your viburnum doesn't bloom, it could be because the species you have planted isn't appropriate for your growing zone. Too much fertilizer that is nitrogen-rich can also discourage viburnum from blooming. The age of your plant can be another factor. If the plant is too young, it might not be ready to bloom. They also need lots of sun. You can normally trim viburnum any time of the year without hurting the plant, but pruning may occasionally lessen the number of blooms.
