Geraniums are versatile plants that grow outdoors in gardens, containers, hanging baskets and even indoors as houseplants. They produce reliable blooms in a variety of colors from spring until fall and are available for purchase at most garden centers. Since geraniums are easy to propagate from cuttings, a more economical option--especially if you want to grow several new geraniums--is to cultivate your own from an existing geranium. Get geranium cuttings in the fall about four weeks before the first frost.
Stop watering the geranium that you are going to cut about two to three weeks before cutting, or about six to seven weeks before the first fall frost.
Choose a branch that looks healthy. The leaves should be green with no spots or browning parts. The stem should be strong and straight.
Cut 3 to 4 inches off the end of the chosen branch. Make a sharp and clean cut with hand clippers.
Begin to grow a new geranium plant from your cutting immediately. Cut off the bottom leaves and plant it about an inch deep in a small planting pot or tray that has moist sandy potting soil. Place it in an area with indirect light until the roots form in a couple weeks.
