Columbia Star thornless marionberries
We are in our second year of production for the 400 berries vines we planted 3 years ago. What do you suggest we do with the 6-10 foot new canes that are everywhere? We've tried tying them up to the wire in between the massive crop of berries that are coming on but that is a daily task. Is it ok to cut them down to say 3-4 feet? I know this will result in side shoots which will make it difficult to tie up to the trellis after this years' crop. Unsure of what to do.
Glad to help. Please call me at 541-231-8854. You can thin canes and tie others. It is some work but I really think you should not cut them. I can explain if you call me tomorrow morning. You can email me at firstname.lastname@example.org but I'm leaving on vacation after that and won't be able to respond to you until late July.
