Q.Dying Rosemary plant
From what I read abut Rosemary plants, even the hearty Christmas variety: there are no symptoms for death by overwatering. My little (16″) tree has been wintering on a 3 sided porch mostly and in the house when temps below freezing. The inside leaves are drying out and dying. Is there any help or is it too late for this lovely little creation? I am in the Pacific Northwest and we just wrapped up a snow and ice storm. We are usually more temperate, but things they are a changing! I mentioned earlier that this is the 4th time I have attempted to maintain this Christmas plant as long as possible. Perhaps it is more like Poinsettia – just for the holiday and pretty much seasonal unless you live in Florida. Right?

The only other thing I can think of other than a watering issue would be a fungus. You could try treating it with a fungicide, like neem oil, to help it recover. If this does not work, you may want to try propagating a new plant from a healthy portion of the tree.
