With its woody trunk and interesting branches, the jade tree resembles a bonsai or miniaturized version of a large tree. A specimen makes a dramatic accent in decor and you might decide you'd like a clone. By creating a new plant from the growth of the existing jade, you will get a genetically identical copy. Clone a jade plant in the spring or summer, when the original jade plant is growing.
Clean the shears or knife.
Cut off a healthy stem section about 2 to 4 inches long. Place the cut so that no stub remains, making it just above a leaf or flush with the branch from which a stem grew. The cutting should include 3 to 4 leaves.
Let the cutting dry until the cut has hardened over a bit. This could take several days to a couple weeks, depending on the size of the cutting.
Shovel the sand, vermiculite or potting soil into the pot.
Plant the cutting into the growing medium. Push the cutting just far enough into the medium so that it stands up on its own.
Mist the growing medium so it is barely damp.
Check the soil every day, misting if necessary to keep it damp.
Add more water gradually as the cutting becomes established. It will take about a month for the cutting to root.
Continue to increase water as necessary as the jade goes from cutting to new plant. Keep the soil moist, not wet.
Re-pot into a permanent container filled with potting soil after the cutting is well-established if you used sand or vermiculite.
