Have you checked to make sure that you have been meeting its requirements? It needs bright, indirect light--no direct sunlight, but it should be within a meter of an open-exposured (no trees or porch roof to block the light) north window, or an east-facing window with a screen to filter the sun. It needs the compost to dry about a cm deep between waterings, and it needs to drain thoroughly after watering. It needs regular, but not heavy, feeding with a high nitrogen, low phosphate, and moderate potash fertilizer--just follow package directions for houseplants. It needs moderate indoor temperatures--around 21º-25º C. Moderate amounts of humidity--about 40%--are good for it, too. If it still has a few leaves, it will probably recover, though it may take a year or more to regain its lost glory.

many thanks for your advice...it is appreciated.
I will give it a feed and water as you suggest and see how we go. Thanks again
