Geraniums

Every year, before the frost, I bring all my geranium plants inside. I keep them in the basement under a grow light and water them occasionally. A geranium is called a tender perennial because it is killed by frost but otherwise will live for years. I have heard that you can hang them in the fall and plant them in the spring but I haven't been successful with that. I haven't bought a new geranium in several years now.
