Mom (in Thurston county) always overwinters her geraniums(Pelargonium)and fuchsia tucked just inside the crawl space under her house. Only loses them if she forgets to water, but that's been less of a problem using Soil Moist. Don't grow them myself, but she's been growing them for as long as I can recall. She roots cuttings during the growing season so has had the exact same bloomin' deck pots for at least 25 years. zzz-zzz-zzz. No idea on the impatiens. Have you considered starting your own from seed?

My dad has overwintered impatiens many times in sunroom. They will look ugly, but come spring they will get leaves again. I think the best way is to take cuttings so that they arent leggy. Thats they way the nurseries do it I think. :-) I have read a lot about keeping geraniums overwinter in the garage. I was going to try it myself this year. Many people apparantly bring them in, bare root and hang them upside down or put them in a paper bag. Sounds scary, but worth a try. They would freeze anyways, so what have you got to lose.
