NO! Do not do a rejuvenation to any Viburnum!! Michael Dirr, who wrote the book on them and who has developed many of them, recommends infrequent and light pruning of Viburnums, if any at all. This is my favorite shrub. I have at least two dozen and about 8 different cultivars. I believe the one you have is a Burkwood, but it could also be Judd. Either way, it's gorgeous, pretty much pest- and maintence free, and you should definitely NOT coppice it. You do that to a Rose of Sharon or a lilac, but never to a Viburnum.

It is beautiful, I love that look. At first I thought it might be one a Sarah Richardson kitchen, but can't find it in her portfolio. The look is called Culture Brick or Cultural Brick and here's one link I found. Here is a link that might be useful: Culturebrick

A DuPont Lawn product called Imprells was killing evergreens. Below is a small paragraph on the subject from 2011. There may me other lawn chemicals dong the same we don't know about. "Imprelis, conditionally approved for sale last October by the U.S. Environmental Protection Agency, is lethal to mature landscape trees including Norway and Colorado spruce, white pines and other evergreens, according to the complaint filed in the U.S. District Court in Wilmington, Delaware. The plaintiffs include operators of the Polo Fields Golf & Country Club in Southfield, Michigan. In the complaint, they said Imprelis has caused “the loss of thousands, if not tens of thousands, of mature pine and spruce trees,” and the nationwide damage “is mounting with no end in sight.” source- https://www.reuters.com/article/us-dupont-imprelis-lawsuit/dupont-sued-over-herbicide-said-to-kill-trees-idUSTRE76E54A20110715
