I would just plant "pot and all" to a depth of the dirt, er, SOIL, in the pot. She can place them where ever she wants the iris ,next year, or anyplace that's "handy", although , I think I would NOT put them where "freeze -thaw" is likely to happen several times over the winter. If she can place them where they are to be eventually grown...in the spring, after the frost has gone out of the soil, she can easily "lift" the pot, and place the un-potted "plug" of dirt, er, SOIL, along with the iris, right back in the same hole!.......Arlyn
