I, too, discovered that geraniums can be saved!
Here in Idaho, I simply cut them back a bit and store them in the unheated garage close to the window, watering them about once a month until spring. Repot or just add new soil...it works! The wimpy-looking ones were planted in the ground last spring and surprised me by producing a plant 3 times as big as it was in the fall. We haven't had a hard frost yet, so I need to rescue them from the elements soon.
