Related to kimbelry's question below, I'm helping friends move some plants...from zone 7 to zone 6. Moving mid-October. Reading through the forums, I gather that we should dig up the peonies, with as large a rootball as possible, and pot them for the move.
They would prefer not to re-plant them right away, as garden plans have yet to be done. What's the best way to overwinter the peonies? Bury pots outdoors? Store in basement? Prepare a temporary garden for the moved plants?
Thanks for your help.
