With the remaining plants pruned back pot them us into large boxes or pots with a John Inness soil based compost making sure the compost is quite dry. Then place them on or near a window sill in a cool frost free area overwinter.Water very lightly every two weeks to stop them totally drying out.Then you will find in February to early March they will have produced a number of shoots that can be again used for softwood cuttings.Then at the end of March re-pot the plants and start to water and feed them before planting them out into the final bedding positions in the garden or your tubs.One final point whilst over wintering the geraniums keep an eye open for fungal infections and remove any dead of damaged leaves or stems.
