The pot can be cracked all over with a hammer and the plant with its cracked container can be repotted into a larger pot lined with fresh soil mix. This allows the roots to penetrate into the new mix while the root system is held firmly together by the cracked pot. Seed is slow to germinate but propagation is readily carried out from cuttings. Cuttings can be taken throughout the year and should have at least three nodes. The leaves should be trimmed to half their length and the base of the cutting dipped in a root hormone solution prior to planting.
Cuttings take three to four weeks to develop roots.
