Dear Sir
orchids grow very well in kolkata dont worry u can start it.
Orchids are very sensitive to direct sunlight and have to be kept in shady place during the summer. We can, however, keep them on direct sunlight on the shelf by the window during the winter from November until March. Imported orchids are sold in the flowerpots. We recommend transplanting into appropriate mixture of soil. We can also grow them in larger vessels, in hanging baskets or wrap their roots with moss and fix them to a piece of tree trunk with the wire.
Water for watering and spraying should be stale, slightly sour (pH 5-6) and warm (20-25°C).
