2 grapes and a blue berry. they were out of blackberry and strawberries. I know the grapes are vining are the blueberries also vining? I also got me 2 sweet potatoe vines. I figured since they were already growing and rooted I might get fruits next year. do I want to plant them on the west, east or south side? I don't have a complete fence on the north that is why I am not asking about the north.
