LIGHT
Vandaceous orchids like a lot of light and often do very well outdoors during the summer. They need to be shaded only if temperatures are high.
WATERING​
Vandaceous orchids like to be watered with high daytime humidity, especially on warm sunny days, essential for good growth. During the summer months, plants may need to be watered as often as every other day—water sparingly in winter, during cloudy spells, or after repotting.
HUMIDITY
Vandaceous orchids should be around 70% to obtain the best growth. This can be provided by grouping plants together or to fill a tray with gravel and keep a layer of water in the bottom of the tray, making sure the bottom of the orchid pots do not come in contact with the water.
TEMPERATURE
Vandaceous orchids will continue to grow any time of the year if given warm temperatures and plenty of sunlight. Night temperatures should generally not go below 55 degrees, although 40 degrees can be tolerated for short periods of time. Daytime temps should remain between 65-85 degrees. Of course, the higher the temperature, the more important the air movement will be for the plant.
FERTILIZER
Vandaceous orchids are very fast growing orchids and, for this reason, are heavy feeders. Fertilize once a week during the growing season and every other week during the winter months. Vandaceous orchids prefer a balanced fertilizer. A fertilizer high in nitrogen tends to reduce flowering.
Our Advice
This should be done in a very porous media, with good drainage being essential. Vandaceous orchids dislike having wet feet, so be sure the roots do not remain wet for long. Many plants are grown in wooden baskets to ensure plenty of air around the roots. When repotting, it is best not to disturb the roots if at all possible. It is easy to drop the old smaller basket into the new, larger one without disturbing the roots. This can be done by carefully removing a plant from a clay or plastic pot, too. Repotting can be done at almost any time of the year, but April through July is the best season.
