Some of the leaves are turning dark green then black (see photo attached). What is my problem and how can I cure it?
Here is a link to raspberry diseases from Michigan State University: http://web1.msue.msu.edu/vanburen/e-1730.htm The leaf curl and mosaic virus can cause the darkening, but I would think you would have mentioned the other patterns associated with those diseases. If you could attach those photos that would help. Here is a link to the attachment "How To" thread: http://www.botanicalgarden.ubc.ca/forums/showthread.php?t=725
