How to Keep Your Houseplants Happy Through the Cold Months
Winter has settled in, and across Canada and the U.S., shorter days and chilly temperatures are officially the norm. As many of us reset our routines and focus on self-care at the start of the year, it’s the perfect time to check in on our houseplants too. Winter can be a challenging season for indoor plants, but with a few thoughtful adjustments, you can keep your leafy companions healthy, resilient, and looking their best until spring arrives!
1. Shield Plants from Cold Drafts & Temperature Swings
While your plants might enjoy bright winter light, the cold drafts from windows, doors, and poorly insulated walls can quickly stress them out. Keep plants a safe distance from drafty areas while still prioritizing light exposure. Sudden temperature changes—like heat vents kicking on and off—can also cause leaf drop or browning edges.
Pro Tip: If moving your plant isn’t an option, insulating windows with thermal curtains or removable window film can help stabilize temperatures while still letting light through.
2. Adjust Your Watering Routine (Less Is More)
Most houseplants slow their growth during winter, which means they need less water than usual. Overwatering remains the number one winter plant mistake. Always check the soil first—if the top inch or two feels dry, it’s safe to water. If it’s still damp, wait a few more days.
Skip fertilizing entirely during winter, as feeding dormant plants can do more harm than good.
Pro Tip: Consider using a simple moisture meter in 2026—these affordable tools can help prevent accidental overwatering, especially for larger pots.
3. Boost Humidity for Tropical Plants
Indoor heating pulls moisture from the air, which can leave humidity-loving plants struggling. Philodendrons, Alocasias, Calatheas, and Ferns are especially prone to crispy edges and curling leaves during winter.
Misting can help short-term, but more effective solutions include:
- Running a small humidifier nearby
- Setting plants on pebble trays filled with water
- Grouping plants together to create a shared humidity zone
4. Make the Most of Limited Winter Light
With fewer daylight hours, even bright homes can feel dim to plants. Rotate your plants every couple of weeks to ensure even growth and watch for signs of low light, such as stretching stems or yellowing leaves.
If natural light is limited, grow lights are a game-changer—modern LED grow lights are energy-efficient, compact, and easy to integrate into your space.

5. Refresh with Seasonal Plant Cleaning
Winter dust buildup can significantly reduce the amount of light your plants absorb. Clean windows regularly to maximize sunlight, and gently wipe plant leaves with a soft, damp cloth to remove dust and grime.
This small habit not only improves photosynthesis but also keeps your plants looking vibrant and healthy during the darker months.
6. Watch for Winter Pests (They’re Still Active!)
Even though it’s cold outside, indoor pests like spider mites, aphids, and mealybugs thrive in warm, dry homes. Check the undersides of leaves and along stems regularly. Early detection makes treatment much easier.
If pests appear:
- Rinse the plant thoroughly in the shower
- Use insecticidal soap or neem oil as needed
Extra Important: Always quarantine new plants for a few weeks before introducing them to your collection—especially during winter.
