Take a nice long stalk with good top leaves, remove the lower leaves, and submerge at least half the stalk in water, with no leaves below the water line. Change the water every few days until roots pop out that are good and long—the more forks in the roots, the better. Kept in water, the clippings will produce fresh leaves and keep growing for a few weeks, and you can pick off leaves while they’re in this state. Alternatively, you can plant the clippings in extremely well-hydrated soil to grow larger, permanent plants, but keep an eye on them because I find that clippings that go directly into soil have a lower chance of surviving, especially for new growers.
