I wanted to try propagating this plant by taking leaf cuttings. This is what I did:
Cut a few leaves from the plant. I've read that it's recommended to take the leaves at the bottom of the plant, not the center. The stalk should look like this:
Put them in moist pot soil. The soil shouldn't be too wet, but don't let it dry out either.
2-4 weeks later, roots will start to develop at the base of the stalk.
