My raspberry plants are dying at the top of the stem. Not all of them, but it looks like I'll be bearing very few berries this season. They are literally turning black. I've never had this problem. The plants are about 10 years old. I usually don't touch these plants. They get enough rain to survive. They are at the side of the house. Not sure what to do. Help!

Do the lower leaves look mottled? The new growth dying is a sign of raspberry mosaic, which is a virus and is not curable. But before saying that this is what it is, could you let us know if there are any other symptoms on the plant? Do the other leaves look odd and when you get berries, what sort of condition are they in?
