Hey Shawn, another Saskatoon berry mega-fan here. I've wondered the same thing myself. I wouldn't hesitate to try it, although I'm not sure about the thickness of the branches. You'd probably have to dig up a mature bush whole to get anything larger than 1" in diameter. I picked some berries at a farm earlier this summer, but didn't really think prunings would do much good. Incidentally, that day, 2 women were 1 row over from me discussing what they were going to do with their old dying apple tree. Of course I ran over, introduced myself and offered to take it off their hands... No phone call yet though.
