Reviewing some of my notes from Bob Solberg about growing hostas in pots, he is in NC.
Uses Plastic pots, repots every 2-3 years, does not water during the winter if in pots, soil should go right to the top of the pot to prevent water from sitting in them over the winter.
Pushes pots together, put white plastic over them and places mouse bait under the cover.
My favorite hostas with red stems are First Blush (great grower), Volcano Island
