    It is possible that there are air pockets in the soil that are affecting the roots. I would step firmly on the root balls to help collapse any air pockets. Flood the area with water to help fill them in. Up its watering as well. It may also have a fungus disease, so I would treat the plant with a fungicide.

    The browning could be from unsual temperature changes or a fungus. Cut out the dead, brown foliage and treat it with a fungicide, like neem oil.

    Put soap flakes around the plant and buds to keep the pests away. You can also try a pesticide. If you are sure there is not a problem with pests, a more radical but effective solution is putting animal blood around the plant, which will scare off many animals trying to eat it. If you are not into the whole blood idea, you can also try putting poison on the buds and over a couple generations, the predators will become ill when eating your plant and they will move on to something else (hopefully not your roses or forsythias haha).

    Cheers,
    Joe

    You can normally prune overgrown shrubs by about a third of their growth, but no more in one given year as this could cause problems. If necessary, you can take another third off the following year until you get them at a more manageable height/shape for your needs. Here is more information that should help: https://www.gardeningknowhow.com/ornamental/shrubs/viburnum/viburnum-pruning.htm

    They could be affected by a fungus, which could be attacking either the roots or the branches themselves. When the branches die, what does that look like? Do the leaves turn brown right off or does some other discoloration happen? Does the whole branch die at once or does it die in a certain pattern? Let us know and this will help us determine what is affecting the plants.

    Viburnums don't require much in the way of fertilizer. That being said, if desired, you can apply a balanced, slow-release fertilizer to the shrub.
