I purchased a Black Satin Thornless blackbery last year. In the first year, I had a couple of canes produce what looked like berries but after flowering, they opened up and took on a pinkish color and never turned black. They almost had more of a raspberry soft texture instead of a firmer berry like the blackberry. I trimmed back the canes that produced these pink berries. The pics I've sent are of this years crop. The plant is planted in a raised bed and lateral canes spread quickly this year. But with the same results. I would love your assistance on how to improve my harvest! Much gratitude and thanks!!
