Vanda Orchid Culture

Posted by Team Orchid-Tree on

Vandas are a family of epiphytic, monopodial orchids with some 50 odd species that are found exclusively in tropical and sub-tropical Asia. With the recent inclusion of Neofinetia, Christensonia and the Ascocentrums along with Aerides flabellata based on DNA studies, the number of species is bound to increase. Light Most vandas in nature are exposed to a fair amount of light since they are found on trees at the edges of branches or where the trees are not too dense.  Those of you who have greenhouses need to have netting that allows 50-60% of light to pass through.  For those...

Catasetum Orchid Culture

Posted by Team Orchid-Tree on

The Catasetum alliance includes the genera Catasetum, Clowesia, Cycnoches and Mormodes, all of which require similar growing conditions.  Plants from the alliance are widespread in the lowland tropics of South and Central America up to elevations of about 1200 - 1500 msl. They have a peculiar habit of producing either male or female flowers both of which do not resemble each other.  They are also very fragrant.  Light Catasetums love plenty of light and can be grown under nets that allow 50-75% light to pass through.  Catasetums are known to produce male or female flowers based on the amount of...

Bulbophyllum Orchid Culture

Posted by Team Orchid-Tree on

Bulbophyllums are a pan tropical genus found across the tropics in all continents except Europe with the maximum concentration in South East Asia.  New Guinea alone has about 700 species within its borders. They have a pseudo-bulb with a single leaf attached to its terminal end.  Each psuedobulb is separated from the next one by a considerable distance.  The inflorescence arises from the base of the pseudobulb and usually carries flowers with a foul smell. Cirrhopetalums and Trias are associated genera that require similar growing conditions. Light Bulbophyllums will do well without direct sunshine and only  in bright light conditions....

Paphiopedilum Orchid Culture

Posted by Team Orchid-Tree on

Paphiopedilums are commonly known as Lady's Slipper Orchids because the lip is modified into a pouch-like structure resembling of a lady's shoe.  They do not come in vivid fancy colours for which most other orchids are known but those who grow paphiopedilums cherish them for being distinct from all other orchid groups. Most paphiopedilums are terrestrial or lithophytic while a few are epiphytic.  All members of the genus are found in tropical and subtropical Asia extending into the Pacific Islands. Light Most Paphiopedilums are low-light orchids since a majority of them are found as terrestrials on the forest floor; however,...

Oncidium Orchid Culture

Posted by Team Orchid-Tree on

Oncidiums are a delight to grow especially for those who have limited space.  They have flowers that come predominantly in the yellow-brown range but of late with a lot of intergenic coming into the market, it is easy to acquire almost any colour you can think of. If grown under ideal conditions, they can bloom several times a year and can also bloom with multiple spikes off a single pseudobulb. Tolumnias or Equitant oncidiums are quite different in that they have succulent leaves and therefore their cultural requirements are different too. Light Oncidiums are broad-leaved indicating that they are well...
