Grow indoors in a loam-based potting compost with added bark and leaf mould in full light during winter, avoiding any draughts. Minimum temperature of 13-15°C ( 55-59°F) during the flowering season. Water sparingly during growth and apply a balanced liquid fertiliser every 10-14 days
Prune back the plants hard in April, to about 10cm (4in). Repot them, growing them in a light, cool place over summer. A temperature of 15-18°C (60-65°F) is ideal. Flowering and bract colouring is initiated by short winter day-length, occurring naturally in December and January. So from November onwards, plants should be put in a dark room after twelve hours of daylight and protected from artificial light sources Plants need a constant temperature of around 18°C (55°F) to colour up well, so make sure they do not get too cold
Propagate by stem cuttings in early summer. Use a hormone rooting compound
