Hanging Vanda Orchids: The right location is crucial
Vanda orchids have very special requirements for the location. The room temperature and humidity are very important. Ideally, you should choose a place in the house or apartment that:
1. is very bright. Unlike other orchid species, the varieties from the Vanda genus require a bright location. But at the same time they do not tolerate direct sunlight. The most suitable are east-facing rooms, glazed terraces or conservatories. On the contrary, the windowsill with southern or western exposure is not suitable.
2. is temperate. There are many varieties that belong to the Vanda genus and each variety has its own requirements for room temperature. Depending on where you want to hang your Vanda orchids, you can also find the appropriate variety. In this regard, it is best to seek advice from a grower. We list several varieties with the optimal room temperature:
- 14° – 18° C: “Vanda Holcoglossum wangii”, “Vanda tricolor suavis”. These varieties do well in heated winter gardens.
- 16° – 19° C: “Vanda javierae”, “Vanda lamellata”, “Vanda pumila”. These varieties are also very comfortable in heated rooms.
Vanda orchids spend the cold season indoors or in the apartment. After the Ice Saints, they are allowed outdoors. Choose a bright place protected from wind and rain.
3. Have a humidity between 60% and 80%. The high humidity is very important for. If the heating dries the air in the room, you can get a humidifier or simply spray the orchid with water once a day to prevent its leaves and roots from drying.
Hanging Vanda Orchids: Hanging plants don’t need soil
Like all orchids, Vanda orchids grow on trees. Therefore, you can do without a substrate. In garden centers are sold special baskets in which the root balls are placed. These baskets are usually transparent and provide enough space for the roots to grow. Some growers hang larger orchids from their stems.
Properly water and fertilize the hanging plants
The hanging plants, like all conventional orchids, are not watered, but dipped twice a week. Simply pour lukewarm water into a wide container and immerse the root balls. After 3 to 5 minutes, remove the orchids from the water and hang them over a trivet. Allow to drain and only then remove the coaster.
Depending on how high the humidity is in the room, you can also spray the orchids with water. If the humidity is 60%, then you should do this every day. If the humidity is higher, it will be enough if you spray the roots and leaves twice a week.
As for fertilizing, you can add special liquid fertilizer for orchids to the water every week. This is necessary during the growth phase and can significantly extend the flowering period.
Vanda orchids: When the roots turn yellow
Orchids of the genus Vanda are quite hardy plants and are very rarely affected by pests. They are mainly susceptible to fungal diseases. Yellow roots are a sure sign that you are watering or spraying the plants too extensively.
The combination of high humidity and low room temperature is a common cause of yellow leaves and moldy roots.
If the room temperature is too high and the humidity is too low, the root balls will dry out quickly and the plant will die.
The room conditions should also be adapted to the phase the exotic is currently in. In the growth phase, the orchid needs more humidity and higher temperatures. During the resting phase, the temperature should not exceed 17 ° Celsius, and the humidity should be 70%.
With their large flowers, Vanda orchids are a real eye-catcher. However, the hanging plants are very demanding. If the light conditions or humidity are not right, the exotic flower can quickly die or stop blooming. Often they need to be adjusted several times a year. That’s why you should measure the room temperature and humidity at least once a week, and check the orchids for yellowed roots or leaves. With proper care, the plant thanks you with an extremely long flowering period.
