Here are a few care tips on how to grow a Vanda Orchid. The two most important things are not to keep the soil overly moist and provide good light and high humidity.
Light: There are strap leafed, terete and semi-terete types of Vanda Orchids. Terete varieties need bright light
and full sun. Strap leaf can handle medium to bright indirect light
. Light requirements for semi terate are somewhere in between the two.
Water: Keep the soil of a Vanda Orchid moist but never soggy. Soggy soil causes root rot and the plant dies. Use a chunky bark mixture or orchid soil that drains quickly and doesn’t retain moisture.
Temperature: Temperatures 55F (13C) to 95F (35C) are best
Humidity: Vanda Orchids like high humidity (80%). Placing a small humidifier near the plant or putting it on a wet pebble tray can help if the air in your home is dry.
: Feed a Vanda Orchid weekly when it is actively growing with a well balanced plant food diluted to 1/4 the recommended strength.
Flowering: The flower spikes on a vanda orchid can produce as many as 6-8 flowers at a time. The flowers come in a variety of colors and can be as large as 5″-8″ in size.
Re-Potting: Don’t be in a rush to move your Vanda orchid to a new container. Vanda orchids should be re-potted every 3-5 years during the spring. Re-pot every three to five years in spring.
The interesting thing about these orchids is that they are usually grown in hanging slatted baskets that contain very little soil.
