- In colder regions, move containers to a sheltered, frost-free location. If planted outdoors, provide a thick layer of mulch around the base to protect the roots from freezing temperatures.
- In containers
- It grows very well in containers, provided the pot is at least 30 cm in diameter and has excellent drainage.
Stem Cuttings
- Take a 10 cm cutting from healthy, non-flowering growth in late summer.
- Remove the lower leaves and dip the cut end in rooting hormone.
- Plant in a well-draining potting mix and keep in a warm, bright spot until rooted.
