December may bring cozy nights and festive lights, but for indoor plants, December can be one of the most challenging months of the year. Reduced sunlight, dry indoor air, and fluctuating temperatures can stress even the hardiest houseplants.
At PetalWhirl.com, we believe plants should thrive year-round—not just survive. This complete winter plant care guide will help you protect, nourish, and grow healthy indoor plants throughout December and beyond.
Why Winter Plant Care Is Different
During winter, most plants enter a resting phase. Growth slows down, water needs change, and light becomes scarce. Understanding these seasonal shifts is the key to successful indoor gardening.
Common winter challenges include:
- Shorter daylight hours
- Cold drafts from windows
- Dry air from heaters
- Overwatering risks
Light Management: Maximize What Nature Gives
Sunlight is limited in December, especially in colder regions.
Best practices:
- Move plants closer to south-facing windows
- Clean window glass to improve light penetration
- Rotate plants weekly to ensure even exposure
- Use LED grow lights for 6–8 hours daily if natural light is insufficient

Watering Wisely in Winter
Overwatering is the #1 reason plants die in winter.
Follow these rules:
- Always check soil moisture before watering
- Water only when the top 1–2 inches of soil feel dry
- Use room-temperature water
- Ensure pots have proper drainage
🚫 Never let plants sit in standing water during winter.
Humidity: The Hidden Winter Problem
Indoor heating strips moisture from the air, causing dry leaves and brown tips.
Easy humidity solutions:
- Group plants together
- Place a tray of water and pebbles under pots
- Mist tropical plants lightly (morning only)
- Use a small humidifier for plant rooms
🌴 Humidity-loving plants: Ferns, Calatheas, Orchids, Monstera
Calatheas Ecuadoriana
Temperature Control: Keep It Stable
Plants dislike sudden temperature changes more than cool weather itself.
Ideal temperature range:
- 18–24°C (65–75°F) during the day
- Avoid drops below 10°C (50°F)
🚫 Keep plants away from:
- Radiators
- Fireplaces
- Cold window drafts
- Air conditioning vents
🌿 Fertilizing: Less Is More
December is not the time to push growth.
- Pause fertilizing for most plants
- Resume feeding in early spring
- Exception: flowering plants may need light feeding
🌸 Winter bloomers: Poinsettia, Christmas Cactus, Cyclamen
