Frillylily said: generally speaking when trying to overwinter things in pots, you should choose plants that are 2 zones warmer than your range. So for example if you live in zone 6 as I do, I would choose a plant cold hardy to zone 4. Have you tried over wintering the pots in a garage/basement where it doesn't get quite that cold?
Thank you for your reply. I don't think there are any peonies for zone 1. As for storing the pots in a garage or basement - I don't have a garage and read that basements aren't cold enough(and if they are water pipes would freeze). I do have a shed but can't imagine hauling 10 gallon pots(which I heard in the minimum size to start) in there and wondered if it mattered that the shed has no windows(light) and if that's needed even though the peonies would be dormant. Also, whether the pots need to be inserted in something to insulate them further(like a box of packing peanuts). I have read that pots can be placed in the ground over winter then lifted out in the spring but can't think of doing that for pots that size.
