It's so devastating because a Vanda orchid refuses the long-awaited blooms. That's no reason to throw in the towel straight away. Often there are minor deficiencies in the care program that can be quickly remedied. Read here how to make the royal flower bloom.
Why isn't my Vanda orchid blooming?
If a Vanda orchid does not bloom, this is often due to a lack of light, dry air or the wrong substrate. To bloom, it needs a lot of light, high humidity and coarse orchid soil made from pine bark or glass pots without soil.
If there is a lack of light, the flowers will not bloom
A Vanda orchid is extremely light-hungry. If the aristocratic tropical beauty refuses to bloom, a lack of light is considered the main cause of the dilemma. In these locations you encourage the orchid to bloom:
- In winter on the south windowsill to get as much sunshine as possible
- From May to September ideally on the sunny balcony
- With year-round indoor cultivation in summer on the windowsill with shading in the blazing midday sun
In addition to a high light output, the Vanda orchid likes to stay at temperatures between 25 and 30 degrees Celsius in summer. If the mercury column does not fall below 18 degrees Celsius in winter, the hybrids in particular will put on their flower dress almost all year round.
Dry air prevents orchids from blooming
Under the influence of low humidity, the Vanda orchid feels so uncomfortable that it is less inclined to delight us with its blooms. Therefore, spray the unwilling plant with soft water every day. In living rooms or in the winter garden, commercially available humidifiers (€36.00 on Amazon) create a tropical room climate.
When spraying, please make sure that you use water at room temperature. In addition, the orchid should not be under direct sunlight at this time.
The Vanda orchid refuses to bloom in soil
If you plant a Vanda orchid in potting soil, you will look in vain for a flower. In the wild, the flower thrives as an epiphyte, clinging to the branches of mighty rainforest giants. You can therefore either cultivate the exotic plant without any substrate in a special glass pot or in coarse orchid soil made from pine bark.
Tip
The root network of orchids is not nice to look at in their transparent culture pot. Specialist retailers have a special flower pot for epiphytic orchids. This has a small platform inside for the planter so that the aerial roots inside do not get waterlogged.
