Red Raspberry Canes
The top portions of some of the new growth canes are wilting and dying. It seems that there are thin light brown lines girdling the canes. We have noticed two "pencil thin" lines about an inch to an inch and a half apart and the leaves above them wilt. The canes break off easily at these lines. Any ideas?
