DO you have the plant? are you hoping to propagate a neighbor's plant?
Planting the berries is fairly reliable.
Breaking off a bunch of stems and potting in a large nursery pot... water and leave in the shade for a few months works well to...
Even just shoving those stems in a hole in the garden often works for me.
I've only potted them with sand, I wouldn't know how they would do with other growing mediums.
