How to care for orchids in winter? Remember these key cultivation points

When caring for orchids in winter, keep the temperature at around 5-15°C, water about once every 20-30 days with water close to room temperature, stop fertilizing so they can overwinter safely, increase indoor ventilation, provide sufficient indirect light, and do a good job of pest and disease prevention before bringing them indoors, so the orchids can grow healthily.

1. Control temperature and prevent freezing

When caring for orchids in winter, do a good job of temperature control and freeze prevention, keeping the temperature at around 5-15°C. Do not let the temperature go above 15°C, otherwise the orchids will start growing, and do not let it drop below 5°C, otherwise they are prone to cold damage that can cause death.

2. Moderate water control

Moderate water control is also the key to how to care for orchids well in winter. At this time the orchids are in a dormant period, and their water needs are greatly reduced, so watering only about once every 20-30 days is enough. The water temperature should be close to room temperature to avoid frost damage to the roots.

3. Stop fertilizing

To help the orchids overwinter better, stop fertilizing in time during care, so the orchids maintain a normal dormant state through the winter. Do not apply light fertilizer, as it easily causes root burn in orchids, and in severe cases can cause the orchids to wither and die.

4. Increase ventilation

Usually when caring for orchids indoors in winter, also pay attention to increasing ventilation for them and keeping the air circulating in their growing environment, so the orchids can breathe and grow better, and avoid poor growth from being in a stuffy environment for a long time.

5. Increase and supplement light

When caring for orchids in winter, also do a good job of increasing and supplementing light. At this time the light intensity is weak, so you can place them in the sunlight to receive sufficient indirect light. If the light is insufficient, you can also use lights to supplement it, so the orchids can grow better.

6. Pest and disease control

When bringing orchids indoors for care in winter, also spray them with medication, so they are sterilized and disinsected before being brought indoors. Usually you can spray fungicidal solutions such as carbendazim or insecticides to kill scale insects, keeping the orchids in a healthy growing state and preventing pests and diseases from breeding.
