Is there anything I can do to save my Fotinia hedge?

re: Fotinia (sp); laurel-like landscaping shrub used in/for hedges (alternating green/bright red leaves)

I have a Fotinia hedge (about 2 dozen plants altogether) along the front property. There are two or three plants right in the middle that appear to be dying back - the rest are quite healthy. Is there anything I can do to restore the dying ones?
