Any ideas on how to keep geraniums over the winter without potting them?

I have no room for flower pots but would like to keep this geranium over the winter and replant in spring.

TAKE THEM OUT OF DIRT AND SHAKE OFF DIRT AS MUCH AS POSSIBLE.PUT THEM IN A BROWN PAPER BAG AND STORE THEM IN A DARK COOL CLOSET.


THEY MAY BE A LITTLE GREEN BY THIS SPRING.BUT THIS REALLY WORKS.DON'T STORE ANYWHERE THEY CAN FREEZE.
Reply:you can also but them in dark pantie hose then store in a cool dry place that's what I do with my Gladi bulbs
