Phalaenopsis & Dendrobium : Best Winter Care + 20 Mistakes and Pro Fixes

Phalaenopsis & Dendrobium Winter can be a challenging time for orchid enthusiasts, especially when it comes to caring for Phalaenopsis and Dendrobium orchids. These beautiful plants, known for their vibrant blooms and unique structures, require special attention to thrive during the colder months. In this guide, we’ll explore the best winter care tips for Phalaenopsis and Dendrobium orchids and highlight 20 common mistakes with pro-fixes to keep your orchids healthy and blooming beautifully.

Best Winter Care for Phalaenopsis Orchids

1. Temperature Control

Temperatures of 65–75°F (18–24°C) during the day and 55–65°F (13–18°C) at night are ideal for Phalaenopsis orchids. Ascertain that the heating system in your house does not produce sharp temperature swings.

Pro Tip: Use a thermometer to monitor room temperatures and adjust your heating to maintain a consistent environment.

2. Humidity Levels

Winter air is often dry, which can affect orchids. Phalaenopsis orchids thrive at humidity levels of 50–70%.

Pro Tip: Place a humidifier in the room or use humidity trays to maintain proper moisture levels.

3. Light Requirements

These orchids need bright, indirect light. Position them near a window with filtered light but avoid direct sunlight, which can cause leaf burn.

Pro Tip: Use sheer curtains to diffuse sunlight and provide even light exposure.

4. Watering Practices 

Watering should be reduced in the winter, as Phalaenopsis orchids require less water because of their slower growth. Make sure the potting media dries out a little bit in between waterings.

Pro Tip: Stick your finger into the soil to check moisture levels before watering.

5. Fertilisation

Cut back on fertilising during the winter months as the plant’s growth slows down. Fertilise sparingly, using a balanced orchid fertiliser.

Pro Tip: Fertilise once a month with a diluted solution to avoid overfertilization.

Phalaenopsis & Dendrobium : Best Winter Care + 20 Mistakes and Pro Fixes

1. Temperature Control

The ideal temperature range for dendrobium orchids is 50–60°F (10–15°C) at night and 60–70°F (15–21°C) during the day. Keep them away from heaters and draughty windows.

Pro Tip: To keep the temperature constant, use a space heater equipped with a thermostat.

2. Humidity Levels

Maintain humidity levels around 50–60% for dendrobiums. Winter dryness can be mitigated with humidifiers or humidity trays.

Pro Tip: Group orchids together to create a micro-environment with higher humidity.

3. Light Requirements

Dendrobiums need bright, indirect light. Winter light is often less intense, so consider using grow lights to supplement natural light.

Pro Tip: Rotate your orchids regularly to ensure even light distribution.

4. Watering Practices

Dendrobiums also require less water in winter. Water when the potting medium is dry to the touch, ensuring good drainage to prevent root rot.

Pro Tip: Use a moisture meter to accurately gauge soil dryness.

5. Fertilisation

Similar to Phalaenopsis, reduce fertilisation during the winter. Apply a diluted orchid fertiliser once a month.

Pro Tip: Avoid fertilising if the plant shows signs of dormancy or reduced growth.
