Dividing depends on having more than one stem coming out of the ground. If there's only one you can't. If there's more than one it's worth a try. The down side would be some rather odd shaped bushes
I sawed a weigla in half a couple of years ago. Bought one with 2 distinctly separate stems, pruning saw down the middle. 2 plants.
