I have a bunch of thornless blackberry plants. The second year growth that bears the fruit is dying after the fruit is set and nearly ripe. I have no idea what is causing the die off or what to do about it. It isn't affecting the whole plant, just one or two canes. It has been a problem for the past 5 or more years. I can't remember when I planted the canes. I have been cutting out the affected canes, but it doesn't seem to be spreading to any other parts of the plant.
