I have a raspberry bush I planted last year that bloomed and set berries this summer, then the berries dried up. The bush/vine looks healthy except for some leaves have been eaten by insects. I found a beetle - metallic dark red on the bush. Could the problem be insects, or could it be fungus. Several years ago I had a peach tree in the approximate location that died of a fungus. When should I prune the canes where the dried up berries are?
