Cultivation

Bulbophyllums are easy to grow.  They like to stay moist, and most of them like warm temperatures.  We grow ours in intermediate (winter) to hot (summer) conditions.  Similarly, they grow well in intermediate light although they can tolerate low light conditions, too (you will see fewer flowers).  I have found increased success since growing mine in a closed tray with a little water standing in the bottom for those in pots.  For plants in baskets, water frequently and from all sides.  Bulbos enjoy regular fertilizer (I use a slow release and occasional additional fertilizer by spray), and may be potted in bark, moss, or a combination of the two.  Because they have short roots, baskets or shallow pots work best for these guys.
