Diana in Wisconsin :" I remember my Grandma taking them out of the pots, shaking off the dirt from the roots and hanging the plants in the basement rafters, then replanting them again in the spring.
Geraniums are the easiest plants to root from cuttings and to save over winter. I’m no longer, ‘in the biz’ so I can share that little ‘trade’ secret now, LOL!"

My experience with geraniums is that overwintered geraniums last longer and are more frost hardy, than those from cuttings.
Cuttings blooms tend to shatter earlier
Is that your experience too ?

I suppose it depends upon how ‘heirloom’ the original plant is. Geraniums have been so hybridized to get different colors, fancy leaves, longer bloom periods, etc. that the more hybrid varieties would be weaker to begin with.
