Tough winter...stayed too warm and then got cold. The plant will be fine. You can prune camelias pretty hard if you want, and definitely cut back dead branches. A few brown leaves here and there isn't a problem.

I have a camellia bush I planted 6 years ago. Every year it has grown and bloomed, but this year all but one of the buds turned brown and about 50% of the leaves are brown and falling off. What's wrong with it and is there anything I can do to save it?
