I have 2 Virginia sweetspire that are taking over my back yard. I'd like to move them to an area where they can spread as much as they like, but they are too big to move all in one piece. Can I just dig them up in 3 separate sections? You can see where the original shrubs were, as opposed to the suckers that have sprouted up on either side of the shrubs. I figured I'd use that as a sort of guide of where to shove the spade. If so, can I do that to my Cornus 'Arctic Fire", too? If I can, I'd like to divide that one next spring, as I don't want to miss the show this winter. Or, (if I can do this), should I only do it in the fall? Thanks for the input.
