Bulbophyllum comprise the largest genius within the Orchid family tree, with over 2,000 species. They are native to a wide range of climates from Australia to South East Asia and into Africa and South America. The flowers are very unique and generally have a strong odor which is made to attract their main pollinators, flies. Some produce single blooms which last only a few days and others have sequential stems with an ongoing show of blooms.
LIGHT they need bright, indirect light to do their best. Bulbophyllums like a bit more light than you’d use for Phalaenopsis but do not need as much light as Cattleyas, Cymbidiums or Vanda’s.
TEMPERATURE Though specific growing requirements vary by species or hybrid, the basics are the same for most. Warm temperatures in the 60’s or above year round. These do not require a winter rest.
WATER most have very fine roots systems and appreciate regular thorough watering. Never allow the potting media to dry completely out, but instead maintain constant moisture in the pot and high humidity in the surrounding area. Watering may be needed 1-2 times per week in some instances. If mounted Bulbophyllums should be watered daily.
FERTILIZING Plants in this group should be given a balanced water-soluble fertilizer about twice a month year round as well. It is best to under-fertilize rather than to over-fertilize.
POTTING in addition to a wide variety of blooms, the growth habit is vastly different throughout the group as well. Some prefer pots, some like hanging baskets and yet still others prefer to be grown mounted onto tree fern slabs or other substrate. Most important thing is moisture retention and good drainage so that air flows around the roots. Repotting should be done when a new growth is showing and during the temperate seasons, spring or fall.
