1. How to water orchids in winter

When watering orchids in winter, they also need to be watered thoroughly to keep the soil slightly moist. However, the frequency of watering should not be too high. The interval should be relatively longer than in other seasons. You can water once every five to seven days. In addition, because winter is relatively cold, you cannot use cold water directly, but use warm water for watering, and it is best to water at noon when the weather is clear. Be careful not to water too much to avoid water accumulation and frostbite the plants. After watering each time, you can place the plant in the sun to reduce the possibility of frostbite. In addition, orchids are generally grown indoors in winter, which is relatively dry, so you should spray them with some water to increase the humidity of the air around them.

2. Precautions for growing orchids in winter

Temperature: The temperature is generally lower in winter. If orchids continue to be kept outdoors, they may be frostbitten or even frozen to death. They must be moved to a warmer place indoors for maintenance. The indoor temperature should be controlled between 5-15 degrees Celsius, and sufficient sunlight should be ensured to help the plant to develop flower buds.

Fertilization: Orchids generally enter a dormant period in winter and do not require fertilization, but some varieties, such as spring orchids, are more cold-resistant and will grow in winter. Therefore, it is necessary to supplement nutrients in time, and you can spray phosphorus and potassium fertilizers on its leaves.

Watering: Orchids are generally in a dormant state in winter, and their demand for water will be greatly reduced. Just keep the soil in the pot slightly moist. When watering, you can use warm water at noon on a sunny day, and you can spray water around it to increase the humidity.

Ventilation: Orchids generally prefer an environment with smooth air circulation, but it is cold in winter and windows are not often opened, which is not conducive to the survival of orchids. Indoor air convection needs to be strengthened. You can open the windows for ventilation at noon when the weather is clear and windless, or temporarily place the plants outdoors in a sheltered and sunny place.
