Keeping Them Growing Geraniums do well as house plants if you can provide them with a cool location and lots of light. Dig them up and pot them just before frost and cut them back. Check the plants over carefully to make sure they are free of insects or disease. Wintering indoors is stressful, so only take indoors plants that are in good condition. Water the plant thoroughly when you first bring them in.
Geraniums prefer to stay relatively dry compared to most plants.
It is possible to take cuttings instead of bringing in whole plants. A cutting is simply a piece of the mother plant. For the best success rate, use tip cuttings. Tip cuttings are made by cutting off the last 3-5 inches of a branch. Try to avoid branches that are blooming.
