Dendrobium bullenianum, culture notes

This is this orchid second blooming on my garden.  My plant if far from being an adult.  This plant presents a particular cultural challenge.  It needs plenty of watering to produce the large, long canes of the adult plant.  And yet, it does better mounted in media that drains freely.  So you have to water this plant often but also need to be watchful that the media doesn't become so decayed and waterlogged to the extent that it will stay wet all the time and kill the roots.
