Planted in fall of 2014 has been doing good, but isn't showing new growth as fast as I think it should. Is a fertilizer a good thing this time of year? It is nice and green, gets morning and afternoon sun with some shade. If I fertilize, what is best? Or are my expectations too high and it just needs more time for growth? Thank you; this is great!

Generally Viburnum are quite a fast growing shrub, but from experience my plantings were slow the first couple of years. Then they took off.
Usually a fertilizer isn't necessary, but you could always try a slow release type. I light feeding won't hurt.
You also may want to top dress the soil with some organic compost this fall. Adding mulch can also help with moisture retention.
