I have a problem with chester blackberries.the vines are loaded but all of a sudden the leaves are turning yellow and the plants are dying.
Pike County Ohio
I wonder if cane cambium tissue on floral canes was damaged by cold temoeratures and drying wind. When this happens, floricanes can look good for some time and collapse in July.
Cane blight, a fungal diease, can be a possibility too. Here is a fact sheet: http://extension.uga.edu/publications/detail.cfm?number=C894
Hope this helps.
