Indoor insulation
The weather is getting colder in winter, and the orchids placed outdoors are vulnerable to the cold current, so they must be moved into the sunny place indoors for maintenance in time p>
If you live in a building at home, you'd better put the orchid basin on a closed balcony, so as to ensure that the orchid has sufficient sunshine, which is very beneficial to the pregnant bud and flowering of the orchid p>
After entering the room, the room temperature should be controlled between 5 ~ 15 ℃, which can be met by ordinary families. However, the room temperature should not be too high, which will lead to slow growth of flower stems and poor development of flower buds p>
Fertilizer control and brightening
Orchids generally do not need fertilization during hibernation p>
The roots of orchids are symbiotic with root fungi. Generally, the pots need to be changed every other year. The soil in China is rich in nutrients, so there is no need to change the pots. However, for Chunlan, it will grow in winter, so it is necessary to supplement nutrients in time and spray a small amount of phosphorus and potassium fertilizer on the leaves p>
Controlled watering
"Don't dry in summer and autumn and don't wet in winter and spring", which is the experience of orchid cultivation summarized by predecessors. Orchids are mostly dormant in winter and need less water. The basin soil can be slightly wet p>
If the basin soil is really dry, it can be sprayed with water at similar room temperature around noon on a sunny day to keep the basin soil slightly wet. It is best to use rain or snow water for orchid watering. If tap water is used, it can be used after two days p>
Ventilation
Orchids like a warm and humid environment with good air circulation. For indoor heating in the north, keep the basin away from the fire. Before and after noon on a sunny day, open the window for ventilation, or place the basin outdoors to avoid the wind and the sun p>
The orchids maintained on the closed balcony should also ensure air circulation and often open windows. But in case of a sudden drop in temperature, close the window immediately to avoid freezing the orchids p>
Disease and insect prevention
In winter, the air is dry and the occurrence of diseases and pests is less. However, for indoor maintenance, if the humidity is high, it is not necessary. It is necessary to spray medicine in time. During normal maintenance, protective spraying shall also be carried out. Bordeaux liquid shall be used to spray the basin soil and the ground around the basin, which can reduce the occurrence of diseases and pests in the second year p>
