Best potting mix for an Odontoglossum

[estación seca]

Sphagnum works well for thirsty orchids in a low-humidity climate if you learn how to use it. You don't want to get it soaking wet unless the plant can suck it dry within a day, or the roots won't get enough air, and might rot. Just moisten the surface so the moss gets evenly damp throughout, and do it again when the moss is nearly dry.
