Professor, I may have asked you this in the past but I couldn't find it using the search engine...but with the black raspberry plants, will last years branches still produce, and will the new strong ones that have sprouted up...produce this year?
I have a white raspberry plant that outgrew the black raspberry plant, 2fold... this thing had very long branches that I *allowed to touch the ground (*did not maintain it properly

) only to realize that at the spot where the branch touched, a new plant started growing. The interesting thing is that sometime real late fall, I trimmed the plant and cleaned up my mulch, but apparently I didn't do a good enough job because now I have about 12 plants out there. None of the old branches have sprouted, do I remove those completely? How do you maintain your plants?
Thanks in advance ~
The check is in the mail.
