Raspberry canes drying & dying
Clinet stopped in with this sample. Planted 20 years ago. Some of the canes are drying up. This is the first year to happen. The canes are cut back to 20 inches in fall and moderately fertilizer with 10-10-10 in the spring in fall by hand. No spraying. There is creaping charley in the bed and pigeon grass and dandelions are pulled by hand. This year the first crop was light. What is happening and what do I do?

this sounds like cane blight. I am attaching a site from Cornell that will help you to manage this disease. I can not be sure exactly which cane blight it is without seeing the plant material. But the control/management is the same for all.
