That might explain why attempts to replace plants that have been cut away from their host trees are reported to fail. If a chunk of wood with the orchid attached is simply wired to a suitable host tree, then there probably isn't a tight enough seal for capillary action to transfer moisture from the new host tree to the mount, even if the host tree is in a perfect microenvironment. I've got four seedlings that I deflasked about 5 years ago and mounted on cork. They are alive and apparently healthy but are growing at the "speed of petrified toenails."* Perhaps I need to try for more constant moisture. In contrast, a Caribbean Dendrophylax** grows much more vigourously. Perhaps it comes from a drier environment. *previously used by Steven Hammer to describe the growth rate of Avonia quinaria in cultivation. **supposedly D. fawcettii, but it likes to keiki instead of blooming, so I can't be sure.
