Each section should have at least one healthy plant shoot and a section of the root system. The divisions should be replanted in well-drained soil and watered regularly until they are established.
Stem cuttings should be taken in the early summer from the current year's growth. The cuttings should be around 10cm long, and the lower leaves should be removed. The cuttings should be planted in a well-draining potting mixture and kept moist. Rooting usually takes 4 to 6 weeks, after which the new plants can be transplanted into individual pots or directly into the ground.
