First hello and welcome Maxie3.

Geraniums need to be protected indoors for the winter.Protected from frost.

Do you have many love to see some photos.

Hello Manxie3, I don't know if this is the correct way but this is what I do. No doubt someone will correct me if I'm wrong.
I pull all the upper leaves and flower stems off, back to the stem. This will encourage new growth.
Then cut the main stem back to about 4 inches, cutting just above the ridges that you can see on them. Leave some of the stronger side shoots on, but also cut these back to a ridge. The cuts should be slanted.
I also nip a bit of the stems out on the ridges, as this also promotes growth.
As Scotkat says keep frost free. The other main problem will be the base of plants and the roots rotting. You need to water sparingly, let the soil dry out and just give a drop of water every now and again, never soak them. I keep mine in the greenhouse over winter with a frost free heater. They will need to be under cover with sunlight available. If you have not got a heater, a fleece will help, as long as we don't get a prolonged spell of freezing weather. I have also put some fresh, dry, multi-purpose compost around the base of all the plants. When the weather is fine let the air circulate around the plants. Finally, don't let the plants flower, until you are ready to move them back outside, and give them a good feed around about March. Sorry if this is a bit long winded, but I have got over 300 plants on the go like this at the moment. Best of luck.

You could take cuttings as well as what Littlelegs suggested just in case it doesn't survive, just use the stems that you remove.

Take cuttings about 3 - inches long. Choose a healthy shoot and cut it from above a leaf joint. Remove all lower leaves leaving just two or three. If there are too many leaves moisture will be lost and the cutting will wilt and die, none or not enough and it won't photosynthesise.

Pop the cuttings into potting compost mixed with fine grit, put them in a warm slightly shaded position (a window sill) and water the cuttings very sparingly keeping the compost barely moist.

Thanks Scotkat, Littlelegs and Myron. I have only just discovered this site and find it great fun. I have a very small garden which I am enjoying now I have retired. I have never had that much interest before. The next questions will be about my fish. If anyone has a pond do you continue to feed the the fish in the winter or do they hibernate? Manxie 3.

I chuck mine in the porch and they continue to flower all winter, such value for money.
Manxie think you had better put your 'fish' question separately so the people that know will see it!

I never feed the fish in the winter, they go to the bottom when its cold anyway, normally they stop eating about end of September, especially if its cold, this year they are still feeding, if they haven`t eaten all the food in 5mins then that is a signal that they are slowing down and then I only feed if they come to the surface when they see my shadow....
