  • Performs best in bright filtered light with shade from hot sun in fertile, moist, humus-rich well-drained soil. Water freely allowing the soil to dry out between waterings. Feed fortnightly with a high-potassium fertilizer.
  • Keep an eye out for glasshouse leafhoppers, mealybugs, thrips, vine weevil and tarsonemid mite. Overwatering may cause rotting at the base of the plant.
  • Deadhead regularly and remove damaged leaves. Mature plants should be cut back after flowering. The plant will remain dormant for up to three months after pruning. Cut back on watering and do not fertilize during this period.
  • Propagate by division of clumps or by leaf cuttings in spring or summer.
