I went with a spade and a kitchen garbage bag in fall. I found a sucker from a large bush, dug out a single spadeful, cutting the root. At home I dug a hole several times larger, dropped my shovelful of dirt and sucker, and backfilled with outdoor potting soil. So basically identical to transplanting raspberries or saskatoons.

In winter, my wild rabbits ate the cutting right down so it was almost flush to the ground. Didn’t seem to bother it. At long as there’s some root mass it’ll pop up. Hardy plants, these.
