Vanda coerulea orchid needs a necessary cool period of rest in winter. In cultivation you can not refrain from watering plants in winter, but they should be very limited. Plants need occasional sprinkling in the early morning and gentle watering once every two weeks. Watering is most beneficial during bright, sunny weather. During 1-2 months in late winter or early spring, the plants should be kept in slightly drier conditions and only occasionally sprinkled. But this orchid is a cool thriving plant.
The Blue Vanda is a plant with moderate thermal requirements. In summer, the average daytime temperatures are 24-25 ° C and the night 18 ° C, with an amplitude of 6-7 ° C. In spring, the average day temperature is 27-29 ° C, night 16-17 ° C, with a daily amplitude of 13-18 ° C. In winter the average day temperature is 22-24 ° C, the night 7-8 ° C, which gives a daily difference of 13-16 ° C. In crops in Chiang Mai (Thailand) plants adapt to winter temperatures around 6 ° C higher than it is due to climatic data.
Cultural information should only be used as a guide, and should be to be adapted to suit you. Your physical location; where you grow your plants, how much time you have to devote to their care, and many other factors, will need to be taken into account. Only then can you decide on the cultural methods that best suit you and your plants.
