Select a 6 or 8 inches pot and ensure that the pot has a drainage hole to prevent the soil from getting soggy as it can lead to rotting.

Fill the pot with loose, free-draining potting mix and make a hole in the center of the pot. Ensure that the hole is slightly wider than the root base of the section.

Place the section in the previously made hole and lightly firm the soil around the base while taking care not to bury it too deep; maintain the section at the same soil level it was in the previous pot.

Water the soil thoroughly and place the set up in a well-lit, warm place until the new plant is well established after which you can begin routine care.
