ing the day and 12-14 ° C at night. They do not tolerate lower temperatures for a long time. Under these conditions they grow continuously throughout the year.
Considering the high temperatures the Vanda they need excellent ventilation to avoid damage to the leaves due to excessive heat.
(For more information on temperature and ventilation see the article: «Temperature and ventilation of orchids»).
There Vanda it is an orchid that needs a lot of light. The needs are different depending on whether it is Vandawith ribbon-like leaves or Vanda with cylindrical leaves Vanda cylindrical or semi-cylindrical in shape are those that more than any other need light, they have to stay in the sun all day. Vice versa the Vanda ribbon-like leaves require direct sunlight for a few hours in the morning, but not during peak hours. They can therefore live in a greenhouse or indoors if their need for light is respected.
The main reason for the non-flowering of these plants is the lack of light.
(For more information on light, see the article: «Orchid needs for light»).
WATERING AND HUMIDITY
TheVanda they require considerable humidity and frequent watering. If they are raised in suspended baskets, watering must be daily in the spring - summer period. During other times of the year, water more moderately to keep the roots moist.
It is a good idea to always water in the early hours of the day, to allow the leaves to dry when the evening arrives.
They need frequent nebulizations, with water at room temperature and possibly not calcareous. We keep in mind that the optimal humidity for this orchid is around 80%. Therefore it should be nebulized daily if not even twice a day.
(For more information on watering see the article: «Watering and humidity of orchids»).
There Vanda it must be fertilized with generosity. Once a week during the period of greatest growth, ie in spring - summer while during the other periods of the year once every two weeks.For this plant that blooms, fertilizers with a higher nitrogen titre that would inhibit flowering should be avoided but balanced fertilizers of the type 20:20:20 (20 parts of nitrogen, 20 parts of potassium, 20 parts of phosphorus) in doses of 1 should be used. gr per liter of water.
To promote flowering once a month it is advisable to fertilize with a fertilizer with a title of 10:30:20.
Given the frequency of fertilizations it is advisable that once a week the plant is watered abundantly with water only in order to eliminate excess mineral salts.It is essential that fertilizations are carried out with the substrate wet to avoid dangerous concentrations of mineral salts that could damage the roots.
It is important never to let the substrate dry completely as there would be an excessive concentration of mineral salts.
Another important thing for the Vanda is to follow a regular fertilizing regimen.
(For more information on fertilization you can consult the article: "Fertilization of orchids").
TYPE OF SOIL AND REPOT
There Vanda it definitely does not like repottings and as they are plants with monopodial development they do not often require this practice. It repots when the basket or substrate deteriorates or when the plant has grown too large to fit in its container.
Their ideal arrangement are in very hard wood strips baskets such as teak or cedar that do not deteriorate easily or in any case in any support that allows the roots to breathe and stay free, not constrained or soaked in water. The ideal are suspended wooden baskets. They can also be grown on cork bark with the roots dangling in the air.
In order not to create too much stress on the roots and if the container is not deteriorated, it is advisable to put everything in a larger container without removing the plants from their original pot. At the time of repotting, with this solution, charcoal, bark and tree fern fiber are added between one pot and another. In this way the plant is not affected in the least.
However, if we must necessarily change the container because it is damaged or rotten, in this case to minimize stress, it is advisable to
