Orchid, back to the tree

I showed this orchid in bloom some days ago, after which I discovered from Cláudio Serique that it would develop better if put on the side of a tree, rather than in a vase. Come to think of it, I never saw one of these rat-tailed orchids in a vase. Always on the trunk of a tree. I tied this one onto a rosewood tree close to the reception center. It seemed to have like the charcoal I had in the vase, so I left the pieces on the root system.
