I usually keep the whole plant inside in the lightest area I have, water it as usual,it'll get quite long and gangly , but in that case I take a few cuttings and start those inside too for next year, I put them in water for about a week and then pot them up. I have a very special geranium that I have brought with me from Denmark and would hate to see it die, so I keep the mother plant year after year, and some years it has been chopped pretty far down but always comes back.Good luck

There are various methods, storing in a paper bag, wrapping in newspaper, etc, but I think with a special plant the only sure way is to dig it out, pot it up, and grow it indoors for winter.

I have a tri-coloured leaf variety. I dug it out, shook the soil off the roots (might not be necessary) and removed quite a lot of the stems but left a few. I repotted into a milk jug and keep on the basement window sill for winter. I wish mine got more sun during winter, but they get bright light and maybe an hour of sun near sunset. I think itÂs important not to overwater, especially at first, until they start getting new leaves. Otherwise they might rot.

I am not sure you have to trim them when you bring them in, but my thinking is to try to make them more manageable, less leaves to spray, etc.

Sometimes, while growing outside, the plant will get numerous stems. Occasionally the stems touch the top or grow just below the soil and will develop their own root. If I see a stem that has any bit of its own root, I cut it off from the main plant and pot it up on itÂs own. I have a couple of these under plant lights to encourage them to develop more roots, but the Mother plant is too tall for lights and on the windowsill.

They will grow a bit in fall, sort of stop during winter, and then suddenly put on good growth in spring from which you can make cuttings with. I usually use the rooting hormone, plant in small cups and put under fluorescent lights method, but I do remember my Grandma rooting them in water.

I've had friends that have had great success just throwing the thing on top of a file cabinet at work under normal ceiling office fluorescent lighting. If they can survive that, a sunny window and normal houseplant treatment ought to be just fine for them.

Last winter, I brought mine in before the first hard freeze, put them pot and all in a dark corner in my basement and ignored them until about March. At that point, I gave them a bit of water, and they started putting out new stems. I brought them upstairs to my relatively sunny kitchen for a couple of weeks and then starting in mid-April, put them outside in one of those bookcase-sized greenhouse things on the south side of my house. seven out of nine survived this way just fine and thrived this summer.

Thanks for all your suggestions. I'm going to give mine a haircut and bring them in. My fingers are crossed.
