How do you dry geraniums to replant in the spring?

A slight variation of that is to dig the plants, shake off most or all of the soil around the roots - CAREFULLY! - trim the tops back by half, and put the plant in a brown paper bag, topside down. Loosely cinch the bag around the stem, leaving the roots exposed, then hang rootpside up in a cool dark place. When Spring approaches, about 5 or six weeks before your last frost date, pot them up and cut the top back to an inch or so, water well and put them in a sunny spot. Works for me about 90% of the time.

I have known people who hung them upsaide down in a dark, frost free area for the winter - just as they were, out of the garden. Then they trimmed them in the spring and potted them up.

I had more success in layering them in a large bos of vermiculite after trimming / tidying them up.
