boysenberry plants

Question

My boysenberry plants are over 6 ft. long, have not produced as yet, but all leaves have fallen off. Do I cut them back or what do I do? Are they dead? I need to know.

Second question: Do I cut my asparagus ferns back now? They are only 1 year old.

Answer 1

Yes, I would cut them back some. This article on thornless blackberry pruning is the same as you would treat boysenberries: http://www.wvu.edu/~agexten/hortcult/fruits/prunblkbr.htm
