OK, so I got my first orchid and over watered. After three days of this, naturally my orchid blooms started to fall off and it looked pitiful. I did some quick reading on the web (wish I had done that three days ago!) and took it out of the pot and carefully removed all the drenched moss from around the roots. It's a good thing I did or mold would have set in for sure. Right now I have the roots exposed sitting on a bed of gravel with a small bit of water in an open pot. I tried to dry out the moss but no luck. I can't get out tonight to get anything else. What can I use temporarily to save my poor naked orchid??
