I would add insulation to the outside of the container. The lotus roots
tend to go in a circle around the perimeter of the pot. The water may stay
liquid, but the soil near the pot sides may freeze. Good luck.

Thank you all-- though once again I have the whole range from ice cubes to
jacuzzi. Knowing that some have done it succesfully is encouraging. I'll
try
the foam board and plastic. Here's looking forward to spring's first
lotus
leaf.
