Winter Orchid Care: Keep Your Plants Thriving

January 28, 2026 295

Winter can be a challenging season for orchids, especially indoors. Shorter days, cooler temperatures, and dry air from heating systems can stress these tropical plants if their care routine isn’t adjusted. With a few simple changes, your orchids can stay healthy and even continue blooming all winter long.

At River Oaks Plant House, we help plant lovers keep their orchids thriving year-round. Here’s everything you need to know about caring for orchids during the winter months.

Adjust Your Watering Routine

One of the most common winter orchid mistakes is overwatering. Orchids grow more slowly during colder months, meaning they need less frequent watering.

Winter watering tips:

Let the potting mix dry slightly between waterings
Water in the morning to allow excess moisture to evaporate
Never let orchids sit in standing water

If you’re unsure, it’s always safer to underwater slightly than to risk root rot.

Provide Bright, Indirect Light

Reduced daylight can impact orchid growth and flowering. Orchids still need bright, indirect light to stay healthy in winter.

Light care tips:

Place orchids near east- or south-facing windows
Keep plants away from cold drafts
Rotate pots weekly for even light exposure

If natural light is limited, a grow light can help supplement sunlight and support continued growth.

Increase Indoor Humidity

Indoor heating dries out the air, which can cause orchids to lose moisture through their leaves.

Ways to boost humidity:

Use a humidity tray with pebbles and water
Group plants together to create a humid microclimate
Run a small humidifier nearby

Aim for humidity levels between 40–60% for best results.

Maintain Stable Temperatures

Orchids prefer consistent temperatures, especially during winter.

Ideal temperature range:

Daytime: 65-75°F
Nighttime: 55-65°F

Avoid placing orchids near heating vents, fireplaces, or drafty windows where temperatures fluctuate.

Fertilize Less During Winter

Because orchids grow more slowly in winter, they don’t need as much fertilizer.

Best practice:

Use a balanced orchid fertilizer at half strength
Fertilize once a month or pause until spring

This prevents fertilizer buildup and protects sensitive roots.

Watch for Pests and Stress

Dry winter air can attract pests like spider mites and mealybugs.

Signs to look for:

Sticky residue on leaves
Fine webbing
Yellowing or wilting foliage

Catching problems early helps prevent long-term damage.
