In winter, the weather is getting colder, and the orchids placed outdoors are vulnerable to the cold current. Therefore, they must be moved into a sunny place in time for maintenance.
If you live in a building at home, you'd better put the orchid basin on the closed balcony, so as to ensure that the orchid has sufficient sunshine, which is very beneficial to the pregnancy and flowering of the orchid.
After entering the room, the room temperature should be controlled between 5 ~ 15 ℃, which can be met by the general family. However, the room temperature should not be too high, which will lead to slow growth of flower stems and poor development of flower buds.
Orchids generally do not need fertilization during hibernation.
The root of orchid has root fungus symbiosis, and it needs to change basin every other year. The soil of China is rich in nutrients, so it does not need to change basin. But for spring orchid, it will grow in winter, so it is necessary to supplement nutrients in time and spray a small amount of P and K Fertilizer on the leaves.
"Summer and autumn should not be dried, winter and spring should not be wet", which is the experience of orchid cultivation summarized by predecessors. In winter, orchids are mostly in dormancy state, requiring less water, and the basin soil is slightly wet.
If the basin soil is really dry, it can be used for spraying water with similar room temperature around noon on a sunny day to keep the basin soil slightly wet. It is better to use rain or snow water for orchid watering. If you use tap water, you can use it after two days.
Orchids like a warm and humid environment with good air circulation. For indoor heating in the north, the basin should be kept away from the fire. Before and after noon in a sunny day, the window should be opened for ventilation, or the basin should be placed in an outdoor place to avoid the wind and the sun.
The orchid placed on the closed balcony for maintenance should also ensure air circulation and open windows frequently. However, in case of a sudden drop in temperature, the window should be closed immediately to avoid the orchid being frozen.
In winter, the air is dry, and the occurrence of diseases and insect pests is less. But indoor maintenance, if the humidity is large, it is not necessarily, we should timely spray the disease. In normal maintenance, protective spraying is also required. Bordeaux liquid is used to spray the basin soil and the ground around the basin, which can reduce the occurrence of diseases and insect pests in the second year.
