Congrats on your first house. If any plant can survive its the daylily. Any tougher and they would be like cockroaches. Potting them sounds best to me and at least they would be out of the wind in your garage. Don't how fast winter comes on in your area but maybe even set the pots against the house and pile some dirt on to the tops for insulation or have dirt hauled in where you are going to make a new bed next year and bury the pots there.
Any way you choose i bet you get a good survival rate or at least i hope you do. Our second house is only half mile away from our first one in the same zip code.
