How to Keep Houseplants Alive (And Thriving) All Winter Long
January 13, 2026 As the days grow shorter and temperatures drop, indoor gardeners are facing the annual challenge of “winter stress” for their houseplants. To ensure indoor jungles remain vibrant, the National Garden Bureau (NGB) is releasing five expert-approved strategies to help plant parents navigate the unique obstacles of the winter season.
While winter conditions — characterized by low light, dry air, and fluctuating temperatures — can be difficult for tropical plants, a few simple adjustments to a care routine can make all the difference.
“Winter might be a wonderland outside, but the indoor environment changes drastically for plants,” says Diane Blazek, Executive Director. “By understanding how light, water, and humidity needs shift during these months, anyone can keep their plants healthy and ready for a spring growth spurt.”
The National Garden Bureau recommends these five tips for winter houseplant success:
1. Maximize Diminishing Light:
With shorter days, move plants closer to south- or west-facing windows. Rotate pots a quarter-turn weekly to ensure even growth, and consider affordable LED grow lights for particularly dim rooms.
2. Combat Dry Indoor Air:
Forced heating zaps humidity, causing crispy leaf tips. To fix this, group plants together to create a “microclimate,” use a humidifier, or place pots on a shallow tray filled with pebbles and water.
3. Clean Leaves for Better Photosynthesis:
Winter dust builds up quickly, blocking what little light is available. Gently wipe leaves with a damp cloth or give smaller plants a lukewarm “shower” in the sink to keep them breathing clearly.
4. Adjust Watering Schedules:
Most plants enter a dormant or slow-growth phase in winter and require less water. Always check the top inch of soil first; if it’s dry, use room-temperature water to avoid shocking the root system.
5. Avoid Temperature Extremes:
Keep plants away from cold window drafts as well as hot radiators or air vents. Most houseplants prefer a consistent temperature between 65 and 75°F.
The NGB also reminds gardeners that slow growth is normal during this time. “Don’t panic if you don’t see new leaves,” says Blazek. “Now is the time to let your plants rest. Save the repotting and heavy fertilizing for spring.”
