Take a 4-inch cutting or cuttings from the north side of the plant. New growth is best, and the cutting should be skinny and pliable. Select a branch that is growing upright and not out to the side. Cut with sharp pruning shears at the bottom and immediately stick the cutting into a glass of water. If the plant is very dry, water well the day before you take the cutting.
Prepare a flower pot for the cuttings by mixing 1 part peat moss to 1 part perlite and filling the pot to within ½ to 1 inch from the top. Dampen the mixture so that it is crumbly, but not soggy. Tamp down slightly, leaving the soil a little loose but level. Using a pencil, poke a 1-inch-deep hole in the soil for each cutting.
Cut off all the leaves on the bottom half of the cutting with a razor knife. Cut the remaining leaves in half across the width. Make shallow slices on each side of the cut end 1 inch from the bottom, extending down to the cut end. The slice should only be deep enough to go through the bark.
Place rooting compound, either powder or liquid, in a small bowl and dip the cut end into it. Place the cut end into the pencil hole you made in the soil. You can place as many cuttings as will fit in the pot, leaving room for ventilation.
Put 3 straws into the soil around the edge of the pot. Place a plastic bag over the pot. The straws will hold it up off the cuttings. Place a rubber band under the rim of the pot to hold it closed.
Place the pot in an area where the soil temperature will stay around 70 degrees F and the cuttings will receive filtered or indirect light. If you don't have an area that will provide the necessary light and heat requirements, place the pot under a lamp with the light on. The light bulb will provide heat and light.
Check on the cuttings once a week, checking for mold or rotting cuttings. Pull out any moldy or rotting cuttings immediately. If the soil feels dry, mist it with a spray bottle and put the plastic back on.
Tug lightly on a leaf in 6 weeks. If it resists, you are starting to get roots. Leave the cutting for another 2 weeks and re-pot. Some cutting can take months to root, so don't toss the cuttings if you don't have roots right away.
