How do I take geranium cuttings?

Using a sharp knife, take 3- to 4-inch stem cuttings from the terminal ends of the shoots.  Pinch off the lower leaves, then dip the base of each cutting in a rooting hormone.  Stick the cuttings into a rooting medium of vermiculite or a mixture of perlite and sphagnum peat moss.  Pots and flats with drainage holes in the bottom are suitable rooting containers.  Insert the cuttings into the medium just far enough to be self-supporting.  After all the cuttings are inserted, water the rooting medium.  Allow the medium to drain for a few minutes, then place a clear plastic bag or dome over the cuttings to prevent the foliage from wilting.  Finally, place the cuttings in bright light, but not direct sunlight.  The cuttings should root in 6 to 8 weeks.  When the cuttings have good root systems, remove them from the rooting medium and plant each rooted cutting in its own pot.  Place the potted plants in a sunny window or under artificial lighting until spring.
