This is pretty easily done. I like to set mine into well draining soil. Water it until it runs out of the bottom. Don't let it sit in water, but let it dry thoroughly before watering again. It will root on its own without much help. If you would like to help it along, you can crush up an aspirin tab and dissolve it into warm water. Let this cool and use it to water. This can help much faster for rooting.
