    The plant could have a fungus of some sort. Other than pruning off dead growth, treat the shrub with a fungicide and see if this helps. Also, be sure to remove any leaf litter from around the plant to prevent spreading of the fungus.

    Most likely some type of Japanese Beetle infestation.
    Treat the plant with Neem Oil.

    It is common for them to look a bit ragged when newly planted, as they are re-adjusting to their new surroundings, especially in very high temps. Also, just to make sure that nothing is restricting the roots from taking in water, tamp down around the plants to collapse any air pockets that may be present.

    Rooting Hormone usually can be found at garden centers or online sources can be found through searches.
    Cinnamon is a great alternative rooting hormone.
    Here are some links for you.

    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.

    Thanks! I will pick some up tomorrow and give it a try. Certainly can't hurt...they look DEAD as in 80 - 90 % brown, dried out leaves. I did also have an unusual insect problem this year in the entire yard (the neighborhood as well) and my husband and I both remarked how many spiders there were this year.

    So, should I prune now? Before or after spraying neem oil?

    Thanks again

    It may be a combination of environmental stresses that are showing on your plants.
    I would suggest a treatment of Neem Oil to help with any fungus issues the plants may be suffering.
    It is safe for plants, people, pets and bees. Neem Oil works as both an insecticide and fungicide.

    Go ahead and trim the plants back, dead head and if the stems are still green and healthy leave them to die down naturally.

    Light pruning can really be done anytime but I would do the big pruning in late winter or very early spring.
    Severe pruning can effect your blooming but if the effect is over all shape and health of the plant, a Viburnum will usually do just fine with heavy pruning.
    Here is a link with more information.
