Orchids like Phalaenopsis and Dendrobium bring beauty and elegance to any indoor garden, but as winter arrives, they need extra attention to stay healthy. Phalaenopsis and Dendrobium Winter Care is essential to help them survive the cold season, maintain their blooms, and prepare for vibrant growth once spring returns.
During the chilly months, these tropical orchids face challenges like reduced light, low humidity, and cooler temperatures. Proper watering, warmth, and light adjustments can make a big difference. With the right care strategies, you can prevent stress and ensure your orchids continue to thrive and display stunning flowers even through winter.
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.
Best Winter Care for Dendrobium Orchids
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.
20 Common Winter Care Mistakes and Pro-Fixes

Mistake: overfertilising during the winter.
Fix: Every month, apply a diluted orchid fertiliser and cut back on fertilisation.
7. Cold drafts
Mistake: Placing orchids near drafts.
Fix: Avoid placing orchids near draughty doors and windows
8. Inadequate light
Mistake: not providing enough light due to shorter winter days.
Fix: Supplement with grow lights if natural light is insufficient.

Mistake: Using the same watering schedule year-round.
Fix: Adjust watering frequency based on winter conditions and plant needs.
15. Failure to repot
Mistake: Neglecting to repot orchids when needed.
Fix: Repot orchids if roots become overcrowded or if the potting medium breaks down.
16. Ignoring Leaf Health
Mistake: Not addressing yellow or wilting leaves.
Fix: Check for issues like overwatering or pests and adjust care as needed.
17. Using Tap Water
Mistake: Using hard or chlorinated tap water.
