Question
Hi,
I have a phalaenopsis orchid. It recently went through some colder temperatures and now the flowers and stem seem to be dying, but the leavs are still growing and in fact, growing nice new leaves. Is there any hope for the flower?
Thank you.  

Answer
Once the flowers start folding, they are done for the flowering season.  Flowering spikes will die back when flowering has finished.  You didn't mention how long the flowers had been open or whether there were unopened buds.  It may be that the flowers were simply at the end of the flowering cycle but cold can definitely affect flowers.

The good news is that you have a healthy plant and next year it's likely to have more flowers. If you can keep your plant healthy, you will be able to enjoy the flowers every year.
