Orchid is very cold, winter is to move into the room for winter, usually when the outdoor temperature is lower than 10 ℃, move into the room, before the frost must enter the room. But don't move in too early. It's better to change the time according to the local climate. For example, in the south, it's a little later, while in the north, it's better to try to move in as early as possible, or it will cause frostbite.
In addition, the entry time is different for different varieties. Guolan can wait for the temperature to be lower than 5 ℃. And Cymbidium and Cymbidium have a certain cold resistance, and it is OK to enter the room again when the temperature is lower than 2 ℃.
1. Temperature: although it is said to move into the room in winter, it is also necessary to pay attention to temperature control, and the minimum temperature shall not be lower than 5 ℃. Room temperature should not be too high, so as not to affect plant growth.
2. Ventilation: pay attention to the ventilation during the winter indoors, and open more windows when the weather is good, so that the air can circulate better.
3. Water control: during winter, the amount of water must be strictly controlled to avoid too wet soil. And watering time should also be close to room temperature, do not use too cold water
