The number of orchid species in nature is estimated at 20,000. There are also very exclusive genera among this wide variety. Vanda is one of them. It is perhaps the most mysterious genus among the orchids, with a unique splendor of color and exotic aerial roots!
The Vanda is native to the southern flanks of the Himalayas and in the region from India to southern China. The orchids grow high in the trees of the jungle. With its long roots, the plant settles in trees. The roots feed on the morning dew and rain.
The Vanda is sold both as a flower and a flowering plant. The flowers of the Vanda have a long shelf life: consumers can enjoy flowering plants and cut branches in the living room for weeks. Due to the slow growth, the Vanda is very robust and the plant can withstand less favorable conditions better than other houseplants.
Vandas do very well at normal room temperatures, between 18 and 27 degrees Celsius. At the right temperature and lots of light, the plant will actively grow all year round.
A Vanda orchid needs a lot of light to bloom. Avoid direct sunlight in summer: this causes the leaves of the plant to turn pale and light green. Leaves can also shrivel. Too little light will cause the leaves to turn dark green. The plant will then no longer bloom. When opening the flower, it still has to come in color.
Extra light in the flowering stage ensures a beautiful bright flower color.
After ten days, the flowers have grown to their full size.
Fill the vase with water twice a week during sunny, warm periods. In cloudy and cool periods this only needs to be done once a week.
When filling the vase with water, the roots absorb the water like a sponge. After about thirty minutes, air bubbles no longer appear and the roots are saturated. Then remove the remaining water from the vase. The plant has now stored enough water in the roots for a number of days.
Use a regular, balanced fertilizer for the Vanda. This is available at a florist or garden center. Add the manure to the water once a month.
When the flowers have finished blooming, the flower branch can be cut out. After a few months, depending on the amount of daylight present, a new branch will appear. Place the plant in a cool place for several weeks to encourage re-flowering. This place should never be colder than 15 degrees Celsius.
In the meantime, the Vanda should receive normal water: the plant does not have a rest period like other orchid species. It is not necessary to put it away in the dark: leave the Vanda in a bright place.
