Getting large cymbidiums to flower in warmer climates

[SueK]

I am unhappy. I have a non flowering large cymbidium which I have had for about 4 years. I bought it when it was in flower and that was the last flower I saw on it. My miniature and intermediate cymbids flower here in Brisbane Australia, but not the large cymbid. In summer we have warm days and it can get up to 35 degrees Centrigrade, but I don't think the night temperature drops low enough to promote flowering. This could be my problem.

I have heard that putting ice or cold water on the plant at night, in the middle of summer may do the trick. Has anyone tried this and does it work? If so, how long should I keep doing this for and how much water or ice should I put on it, as too much water would obviously be a disaster? Or does anyone else have a trick up their sleeve?



Thanks
Sue
