When I lived in Germany I used to cover my geraniums with burlap. They would die back some but would always be hearty in the spring. When I want to propagate a geranium, I just use a cutting and throw it into a jar with fish emulsion and place it in a sunny window for the window.

Thank you, I don't think the burlap would work here. These are in pots, and we get very very cold. I think I will take some cuttings, pot them up and see what happens.

tender geranium are very easy to propagate from cutting, just push the cutting into the soil in a cooler shady area or under other plants - you can cover it with half coke bottle (take the cap off).
To overwinter tender geranium, wash the whole rooted plant to remove the dirt  let it dry out; then put it in a paper bag and store it in a dry place. Re-pot the plant around the middle of March making sure you cover it with clear plastic sheet to provide consistence humidity; you will be amazed how good they will perform. Seham

Thanks!
Although I think I might have waited to late to try this. I don't have an area inside my house to keep plants in a sunny window all winter. And we will have frost here any day now. I think I will try to root a couple cuttings, just to see if I can. I will also try to keep the potted geraniums over winter again, as I have in the past. The only one I have ever had success with is the pink one. And I have no idea which variety or cultivar it is. I inherited it from my mother in law 3 years ago.

Propagating geraniums is very easy. Use a light soil mix with extra perilite. Take cuttings about 3 - 4" long. Strip off lower leaves, only leaving the top 2. If leaves are big, cut them in half.

NOW, let them dry out to callous. Usually 24 hours. This keeps them from rotting. Once I learned this, I have almost 100% success.

Plan them in individual 3" - 4" pots. They'll seems flimsy. They'll come back!

Mist with water every day or two.

Plants will start growing in about 3 weeks.
