companion planting

[Big B]

I am a born again orchid grower. A lot has changed in the orchid growing world since I was last active a quarter century ago. For instance, back then I was ridiculed for using metal halide lighting because it was so obviously wrong and fluorescents were the only way to go because everybody was using them and HID would be different and wrong and blah blah blah. Now it seems HID lighting is just using the obvious. Another weird uppity idea I had back then was companion planting for orchids.

The local orchid society had their annual spring show last week. I noticed that some of the plants I bought came with their very own spanish moss pre-attached. Has companion planting for orchids become a common practice now? If so, where do I go to find out more about how it is done these days? Also, what are the recommended species for companion planting?
