the summertime boysenberry growth

We are in the middle of gorgeous weather with blue skies and moderate humidity. We just had the remnant of a tropical storm pass through a few days prior. It dropped enough rain to dirty the cars but we still have a bit of humidity in the air. This morning, when I got to my plot, I noticed how the boysenberry bush is working overtime, putting out canes for next year, resulting in this piling of the green. These canes will be the ones to bear fruit next year. In the meantime, one of the tasks on my list is to hunt down this year's canes, which bore this year's fruits, and to cut them back. Good luck, as they are buried somewhere underneath the newer branches.
