You can treat them as houseplants for the winter if you have space. They require lots of sun and watering about once per week. Feel free to cut them back, since they'll send out new, tender growth and blooms. Another way to overwinter geraniums is to store them upside-down. Dig up the plant before frost hits. Shake all the soil from the roots, put a paper bag over the entire plant, and store it upside down (roots up, stems down) in a cool, dry place (in a box in an unheated garage or crawl space is great). In late March, plant the geranium in potting soil in a container big enough to accomodate the roots. Water thoroughly and place in a cool (40-45F) location that receives bright yet indirect light. As the stems sprout leaves, move into direct sun and apply an all purpose fertilizer following application instructions. Remove any dead stems before setting outside. After few years your geraniums will become woody and produce fewer blooms -- at that point, you can start new plants from cuttings.
