American Holly leaves brown spots, spreading
I recently (December 2011) planted two American Holly bushes on my property. During the past few weeks, I have noticed that the leaves would start to turn brown (usually at the tips) and then spread over the entire leaf. The brown leaves are spreading over the entire plant. I have searched for Holly diseases and really could not find anything. I think maybe it's winter damage, but the winter was very mild this year. Can anyone please tell me what this is, and how to treat it? Please see link to a picture. Thanks.
