Re: grocerystore ginger root
You'll need a piece with at least one "knot". Loves banana soil. Very invasive -- although your winter would take care of that! I advise a pot or raised bed. Depending on the source, some of the ginger root in the stores is "dead" due to treatment or freezing during shipment. Its a hit-or-miss thing, since the sources change throughout the year.
