Vantaas are doing very well at normal room temperatures, between 16 and 25 degrees Celsius. At a proper temperature and a lot of light, the plant will grow actively throughout the year.
To blossom, a Vantaa orchid needs a lot of light. Avoid direct sunlight in summer: this leaves the leaves of the plant dull and light green. Also, leaves can shrink. Too little light will make the leaves dark green. The plant will no longer bloom. When opening the flower it must still be colored.
Extra lot of light in the flower stage ensures a beautiful bright flower color.
After ten days the flowers have grown to their full size.
Fill the vase twice a week with water during sunny, warm periods. In cloudy and cool periods, this only once a week.
When filling the vase with water, the roots suck the water as a sponge. After about thirty minutes no bubbles 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 Vantaa. This is available from florist or garden center. Add the manure once a month to the water.
When the flowers have flowed out, the flower branch can be cut out. After a few months, depending on the amount of daylight available, a new branch will appear. Put the plant away for a few weeks in a cool place to promote herbivorism. This place should never be colder than 15 degrees Celsius.
In the meanwhile, the Vantaa must usually get water: the plant has no rest period like other orchids. Doing away in the dark does not have to:
Let the Vantaa be in a light place.
