Growing new plants from another plant is known as propagation. Some of the more common methods of propagation include seeding, root division, air layering and by cuttings. Taking cuttings of a plant, whether still growing or uprooted, is the easiest method. If done properly, you can end up with a garden full of new plants from just one mother plant. Make sure that the cutting instrument is very sharp and all of your materials are sterile.
Look for a healthy stem with several leaf nodes (where the leaf joins the stem). Cut the stem, just below a leaf node, at an angle. Further cut this piece of stem into 4- to 6-inch lengths. Make sure each section has at least two leaf nodes.
Remove all flowers or buds from the cuttings, and remove all leaves from the lower third.
Pour the potting mix into the pots to within 1/2 inch of the rim. Water the soil well, allowing the excess to drain from the bottoms of the pots. Place the pots in a gardening flat.
Dip the cut end of each section of stem into the rooting hormone, and tap it gently against the side of the jar to remove any excess.
Create a planting hole in the soil with your finger or a pencil. Place the cut end of the stem into the hole and gently press the soil around it. Make sure that you have buried at least one, preferably two, leaf nodes. Sometimes you may need to bury almost the entire cutting in order to achieve this. As long as there are one or two leaves exposed above the soil, the plant can still carry out photosynthesis and should be fine.
Wet the soil with the misting bottle set on a fine mist to ensure contact with the cutting.
Place the flat in a well-lighted, draft-free area. Keep it out of direct sunlight, and check the soil daily to be sure it remains moist but not soggy. Rooting should occur within 10 days to two weeks.
