Since you already have a species more suited to more northern climates, you will need to do some sun shading during the hottest parts of the summer months.
Good luck, my experience is that the more you leave these sorts of berries to their own devices, the better they reward you.
Pruning is just like for black berries, cut the canes back in the fall, leaving around 3 feet of old cane. That way they don't turn into a "bramble patch" Like Brer Rabbit loved to live in.
