Watering requirements: In summer, water to maintain a moist soil condition. In winter, it should be less springy to thumb pressure, though particles adhere. Avoid splashing the leaves; water stains them. It likes high humidity.

General care: Give weak liquid feed weekly while growing. Pinch out growing tips to force it to branch and produce a good bushy shape. If you do not, the plant grows leggy and ungainly.

Rest: It rests in winter. As growth ceases, reduce water and stop feeding. Re-pot in spring. Cut back stems to half their height and maintain a moist soil condition. Six weeks after re-growth begins, resume feeding.

When it looks sick:

  • Poor colouring : This results from insufficient light. Improve the light but do not place the plant in direct sunlight.
  • Dry, dusty-looking leaves, lacking a healthy sheen : Inadequate humidity will cause this. Improve the humidity and mist-spray regularly.
  • Stained blotchy leaves : Caused by water splashes. Always shake them off.
  • Poor growth and yellowing foliage : Water the plant with a oz magnesium sulphate (Epsom Salts) to 1 pint of water-30 gm to 1 litre.
