Orchid Care Tips for Winter: Nurturing Your Blooms Through the Cold


As winter approaches, orchid enthusiasts may find themselves facing new challenges in maintaining their cherished collections. The drop in temperature and changes in humidity levels can have a significant impact on the well-being of these delicate flowers. In this blog post, we will explore essential tips for caring for your orchids during the cold weather, offering insights into both indoor and greenhouse cultivation.

Indoor Orchid Care:

  1. Temperature Control:

    • Orchids are sensitive to temperature changes, especially during winter. Maintain a consistent temperature range between 60-75°F (15-24°C) during the day and slightly cooler at night.
    • Avoid placing orchids near drafts, radiators, or heating vents, as sudden temperature fluctuations can stress the plants.
  2. Lighting:

    • As the days grow shorter, provide ample light for your orchids. Consider supplementing natural light with artificial light sources, such as fluorescent or LED lights, to ensure they receive the necessary 12-14 hours of light daily.
  3. Humidity:

    • Indoor heating systems can lead to lower humidity levels. To counteract this, use a humidity tray filled with water or place a humidifier in the orchid's vicinity. Regular misting can also be beneficial.
  4. Watering:

    • Adjust your watering schedule to accommodate the plant's reduced growth during winter. Be cautious not to overwater, as orchids are susceptible to root rot in cooler temperatures.
    • Water early in the day to allow excess moisture to evaporate before nightfall.
  5. Air Circulation:

    • Ensure proper air circulation by spacing orchids to prevent the onset of fungal diseases. Gentle air movement helps in preventing stagnant air pockets, reducing the risk of infections.

Greenhouse Orchid Care:

  1. Heating:

    • Install a reliable heating system in your greenhouse to maintain a stable temperature. Greenhouses should ideally stay within the 60-70°F (15-21°C) range to mimic the orchids' natural tropical environment.
  2. Insulation:

    • Insulate the greenhouse to retain heat. Bubble wrap or thermal blankets can be used to cover windows and walls during the coldest nights.
  3. Ventilation:

    • Adequate ventilation is crucial in a greenhouse to prevent condensation and fungal issues. Use roof vents and louvers to regulate temperature and humidity levels.
  4. Shading:

    • During exceptionally sunny days, provide shading to protect orchids from excessive sunlight. This can be achieved with shade cloth or by applying a thin layer of white paint to the greenhouse exterior.
  5. Monitoring:

    • Regularly monitor the environmental conditions inside the greenhouse using a thermometer and hygrometer. This allows you to make timely adjustments to ensure optimal growing conditions for your orchids.


Caring for orchids during the winter requires a thoughtful approach to address the unique challenges presented by the cold weather. Whether you're cultivating them indoors or in a greenhouse, maintaining a stable environment is key to keeping your orchid collection healthy and vibrant throughout the winter months. By following these tips, you can enjoy the beauty of your orchids even when the weather outside is chilly.
