Watering orchids in winter also needs to be thoroughly watered to keep the soil slightly moist.But the frequency of watering can not be too high, the interval time is relatively longer than other seasons, you can water once every five to seven days.In addition, because the winter is cold, can not directly use cold water, but to use warm water to irrigate, and the best weather at noon watering.Be careful not to water too much, so as to avoid water accumulation and frostbite plants.After each watering, the plants can be put in the sun to reduce the possibility of frostbite.In addition, orchids are usually cultured indoors in winter, which will be relatively dry, so it is necessary to spray some water appropriately to enhance the air humidity around them.
Temperature: The temperature is generally low in winter. If the orchid is kept outdoors, it may be frostbitten or even frozen to death. It must be moved indoors to a warmer place for maintenance.Indoor temperature should be controlled between 5-15 degrees Celsius, and ensure adequate sunshine, which is conducive to plant bud breeding.
Fertilization: Orchids generally enter the dormant period in winter and do not need to be fertilized, but some varieties, such as Chunlan, are relatively cold-resistant and will grow in winter.Therefore, it is necessary to supplement nutrients in time, and phosphorus and potassium fertilizers can be sprayed on its leaves.
Watering: Winter orchids are generally in a dormant state, the demand for water will be greatly reduced, as long as the pot soil can be kept slightly moist.When watering, warm water can be used at noon on sunny days, and water can be sprayed around it to increase humidity.
Ventilation: Orchids generally prefer an environment with relatively smooth air circulation, but it is relatively cold in winter, and they generally do not often open windows, which is not conducive to the survival of orchids.It is necessary to strengthen indoor air convection, open windows at noon when the weather is clear and windless, or put plants temporarily outdoors in places where there is wind and light.
