I recently purchased a beautiful viburnum – in part because of all of their wonderful characteristics that I raed about on this blog. Unfortunately, I had to go out of town unexpectedly and the plant dried out b/c it was just sitting in its pot. When I returned, all of the flowers were shriveled and the leaves drooping. I watered it and some of the leaves seemed to revive, but then they ALL dropped off. There are a few leaves that seem to be starting from scratch, growing anew. But is there anything that I can do for it? Any help would be greatly appreciated. Thank you.
