How to raise orchids indoors with heating in the north

Orchid east winter problem, personal advice, do not freeze do not enter the house, reasons: 1, orchids first to vernalization, followed by severe cold next year to be stronger. The buds of orchids differentiated better after low temperature. 2. The heating room is so dry that the moisture is uncontrollable, dry and stuffy. Last year, I was steamed down a pot of seedlings that had been raised for more than a decade. Water, weak acid in the south, alkaline in the north.

Air humidity, this is the most important, high air humidity in the south; dry in the north. In the south, there is no need to take protective measures, as long as there is shade, but not in the north, it is easy to handle in summer, so cool it; in winter, the heat will soon dry the orchids, and simply artificially increasing the air humidity will not work at all. I have done experiments and found that it is OK to symbiosis with other southern plants in a large protected greenhouse, but it is difficult to raise alone.

With regard to the temperature difference, it is generally believed that the temperature difference between day and night should be about 10 degrees, which is most suitable to make nutrients from carbon dioxide absorbed during the day, and to release energy at night to synthesize the necessary substances, such as enzymes, sugars, media, etc., so it is also very important to have a temperature difference. There is no temperature difference when heating is open in the north, which may be inferior to that in the south.

Too high and too low temperatures are disadvantageous to the growth of orchids. The best temperature for the vegetative growth of orchids is between 20 and 25 degrees Celsius, and if it is below 15 degrees Celsius, it will enter reproductive growth.

It is recommended to increase humidity in the heating room, open windows at noon to breathe, if the temperature is too high to cool down, do not put orchids near the radiator, to stay away from the radiator. Orchids certainly can not be vernalized in this environment, if you want to vernalization, put the orchids outside the balcony, but pay attention to the low temperature to prevent frostbite.
