|Well, Patrick...if they get "rooted in" before the ground freezes......they*should* be able to handle anything winter might throw at them. That said, I know some folks apply a "mulch", after the ground freezes, to help prevent 'heaving" of the rhizomes.....and then remove it, very early in the spring. I've never done that with bearded iris....so, I would have to *guess* that you would want something that won't "pack down".....pine straw, or maybe straw ? Maybe someone who has done , or still does, do it, will chime in.|
