I think that I am going to have an orchid tree in my atrium, which is really just a covered porch of sorts. I am wondering if a live tree would work or if I should use a stick, or even build it out of cork. What do you all think? I prefer the live tree method, I would just need to find one that could tolerate the orchids and moss and frequent wetness that would be associated with growing orchids on it. Then there is size requirements as well as cultural. thoughts?
