Hello group
I need some help. At the Houston orchid show I bought Phrag. besseae 'Haven" X besseae 'smokin.' This was Saturday. I put it in my greenhouse, Sunday, and watered it. I look at it every day when I get home from work. It had a beautifuf orange flower, with buds below. Today when I looked at it the flower had fallen off. It does not look like something ate it or cut it off. Looks like it just dropped off. Any ideas, or suggestions on the culture? I have moved it in the house with my Phals. It looks as if it is growing in sandy , small rocks. I plan to repot saturday.
Help if you can.
