Lycaste bradeorum (plant habit!)

[JP020366]

Hi all

I have a lycaste bradeorum which still hasn't lost it's leaves. It's now beginning winter here in Sydney and I thought this would have happened by now.

Is this unusual and posibble it will just happen a bit later? Any chance the leaves may not drop at all and should I keep watering until they do, or just stop now?

The weather is cooling down but not sure what temp triggers the leaves to fall.

Appreciate any comments.

Cheers

John
