For some reason, whenever Disas are mentioned, a number of orchid growers throw up their hands, exclaim "Those are impossible to keep alive", and proceed to tell you some horror story about Joe Blow's trials and tribulations with Disas. My purely personal opinion is that they are not difficult to grow if you have decent water and forget about the fact that they are an orchid. Most Orchid growers primarily raise epiphytes. That is, a class of orchids that is used to growing on trees with the roots in the air.  When orchids are grown this way, they get very disorganized and roots can ramble all over the place taking up lots of space.  Most orchid growers grow in small areas and can't offer the plant it's natural conditions so they attempt to grow the epiphytic orchids in pots with various potting material.  When grown this way, one must be careful to let the media dry out a bit between watering or else the roots, which in nature are waving in the breeze, will certainly rot.  Orchid growers have heard for years that the one thing they must avoid is watering too frequently.  With Disas, it is hard, but you have to forget all those admonitions. It's perfectly fine to water Disas daily and some even do it constantly, in hydroponics tanks. In nature, Disa uniflora is exposed to lots of water and instances have been observed where the plants were literally under water when the annual rains swelled the stream by which they grew.  In the following section, I have presented my opinion about some of the key components of Disa culture.  As in everything in life, nothing is written in stone.  This cultural advice mainly applies to Disa uniflora and it's hybrids and is based on my own experiences.
