When to plant: spring
Overwintering: Bring the plant indoors before the first frost. Place it in a bright window and reduce watering significantly during the cooler months.
In containers: It grows very well in containers, provided you use a pot at least 12 inches wide with excellent drainage.

Stem Cuttings

Take a 4 to 6 inch cutting from a healthy stem.
Remove the lower leaves and dip the cut end in rooting hormone.
Place the cutting in a moist, well draining potting mix.
Cover with a plastic bag to maintain humidity until roots form.

Group plants with similar water needs together to maintain consistent humidity levels.
