How do I control fungus on indian rope hoya?

I've had this plant on my windowsill for a year, and it's growing very slowly, but produced no flowers. It has a white covering over many of the leaves (inside the creases) and keeps spreading to the new growth.

Hi Rosada,

What a shame your hoya is not doing as well as you would like at the moment. Without seeing the plant it is difficult to know whether this white covering has been caused by a fungus or by an insect. It could be a soft scale that has appeared on the foliage of your vine. Scale can be controlled by using a product called PestOil, which will work by suffocating the pest. It may also be a fungus called powdery mildew. This fungus can be controlled by using a product called Fungus Gun, a systemic fungicide. It can be applied every 14 days until the infestation is under control. It might be a good idea to take a leaf down to your local nursery who will be able to properly diagnose the problem for you.
