Answer: Ilex crenata 'Hoogendorn'is an evergreen and should not turn brown at all, so these may be dead. I would strongly suggest you consult with your landscaper or retailer if there was a warranty. This type of failure can be caused by inadequate watering, overwatering, transplant shock, poor rooting, or possibly by a pest or disease problem. Your local professionally trained nurseryman and/or county extension should be able to help you determine what happened so you can have better success with any replacements -- either the same shrub or something else.
