I have several viburnum shrubs on side yard. I love them; however, they have grown too large. I very much want to cut them back to about three feet. Do I dare do that this fall? I really need to cut them back as I have undesirables growing among them, such as wild grapevines adn polk salad, and can’t get to these pests without trimming the shrubs.

You can trim viburnum any time of the year without hurting the plant. But pruning now may lessen the number of blooms for next year. If that is ok (it will recover for the year after), then you can prune.
