Answer: The symptoms you describe could be related to the plant drying out, but with a holly the problem may exist for quite a while before it is noticed. Since the neighboring plants seem to be normal I would suspect something is amiss underground. You might want to look carefully for signs of root damage or insect or disease problem and possibly consult with your county extension to identify the cause for the drying out. When watering, be careful to keep the soil evenly moist rather than sopping wet; while it is a good idea to provide adequate water, overwatering is not helpful.
