Winter is hard on indoor plants. Shorter days, dry indoor heat, and cold drafts all stress your greenery at once. But here’s the good news: caring for indoor plants in winter just means adjusting your routine. Once you know what to change, keeping your plants healthy through the cold months is totally doable.
Reduce Watering Frequency in Winter
The biggest mistake people make in winter? Watering on the same schedule as summer.

When it’s cold, your plants grow slower or go dormant. They use way less water. Overwatering in winter is the fastest way to kill a houseplant.
Instead, let the top inch of soil dry out before you water again. Stick your finger in the soil to check. If it feels damp, wait a few more days. This simple test beats any watering schedule.
Most indoor plants need watering only once every 2-3 weeks in winter, compared to weekly in warmer months. But it depends on your plant type, pot size, and home humidity. Pay attention to what your plant tells you.
Use Lukewarm Water, Not Cold
When you do water, always use lukewarm water. Cold water shocks plant roots and can damage them.
Lukewarm water also does double duty: it helps your plant absorb water better and it adds a tiny bit of humidity to the air around your leaves. Win-win.
Let tap water sit at room temperature for a few hours before watering, or run it under warm (not hot) water for a few seconds. Your plants will thank you.
Fight the Dry Indoor Air with Humidity
Central heating systems suck the moisture out of your home. Indoor air in winter can be drier than a desert.
Your plants are suffering. Dry air makes leaves crispy, slows growth, and invites pests like spider mites.

Here’s how to add humidity back:
- Mist your plants 2-3 times a week with lukewarm water. Focus on the undersides of leaves.
- Group plants together. They create a small humid zone around each other.
- Set pots on trays filled with pebbles and a little water. As the water evaporates, humidity rises around the plant. Don’t let the pot sit directly in water or roots will rot.
- Use a humidifier near your plants if you have one. Keep it on low to medium.
If you want to get precise, grab a cheap hygrometer from any hardware store. Most indoor plants like humidity between 40-60%. Knowing your home’s humidity level helps you dial in the right care.
Be Strategic About Window Placement
Winter sunlight is weaker and comes from a lower angle. That might sound like less light, and it is, but there’s a flip side.
Cold drafts and temperature swings near windows actually stress plants more than the reduced light does.
Move heat-sensitive plants like calatheas and philodendrons a few feet away from cold windows. You want bright, indirect light without the cold shock.
Plants that love light, like succulents and snake plants, can handle a sunny window better. Just make sure they’re not touching cold glass on the coldest nights.
If a window is your only bright spot, that’s okay. Move your plant back a little or hang a sheer curtain between the plant and the glass to soften drafts.
Add Supplemental Light if Your Home is Dark
Shorter days mean less natural light. If your home doesn’t get bright windows, your plants will slow down or get leggy (stretching toward any light source).
Grow lights are the fix. You don’t need anything fancy or expensive. A basic LED grow light from any hardware store works great.
Place a grow light 6-12 inches above your plants and run it for 12-14 hours a day. Your plants will stay compact and keep growing through winter.
This is especially helpful for plants in interior rooms or homes with small windows. A little artificial light makes a huge difference.
Clean Your Plant Leaves Regularly
Dust builds up on leaves faster in winter because nobody opens windows and air is stagnant.
Dusty leaves can’t absorb light or breathe properly. They also hide pests.
Wipe leaves gently with a soft, damp cloth every 2-3 weeks. Microfiber cloths work beautifully. For plants with fuzzy leaves (like African violets), use a soft brush instead.
Skip the leaf shine products. Plain water is all you need, and it won’t clog your plant’s pores.
Pause or Reduce Fertilizing
Most indoor plants don’t grow much in winter. They’re resting.
Feeding a dormant plant does nothing but waste fertilizer and can actually burn roots if you’re not careful.
Cut fertilizing way back. If you normally feed every two weeks, switch to once a month or skip it entirely until spring. Your plants will tell you if they need nutrients by new growth slowing to almost nothing, which is totally normal and healthy.
Resume your regular feeding schedule when you see new growth pick up in spring.
Watch for Pests More Carefully
Indoor heating and dry air create the perfect storm for houseplant pests like spider mites, scale, and mealybugs.
Check your plants weekly. Look under leaves and along stems. Catching pests early means you can handle them with a simple spray of water or neem oil before they get out of hand.
If you catch an infestation, isolate that plant away from others right away. The combo of good humidity (which we talked about earlier) and regular leaf cleaning will prevent most pest problems.

Keep Consistent Temperatures
Sudden temperature swings stress plants. Avoid placing plants near heater vents, radiators, or drafty doors.
Most houseplants are happiest between 60-75 degrees Fahrenheit. Winter indoor temps usually fall into that range, which is good news.
Just don’t let plants sit next to a heater blowing warm air directly on them all day. That dries leaves out fast and causes stress.
A few degrees of temperature variance is fine. It’s the big swings and direct heat that hurt plants.
Adjust Your Routine by Plant Type
Not all plants need the same winter care. Tropical plants like pothos and monstera slow down but still need decent light and warmth. Succulents go dormant and barely need water at all. Ferns stay thirsty even in winter.
Know your plant. Check what it likes and adjust watering, light, and humidity based on its needs, not a one-size-fits-all schedule.
If you’re not sure what you have or how to care for it, Nature Indoors can help you figure out the right approach for your specific plants and space.
The Bottom Line on Winter Plant Care
Winter plant care comes down to three things: less water, more humidity, and paying attention to temperature and light. Once you lock in those basics, your plants will sail through the cold months.
The key is remembering that winter is a slow season for plants. They’re not failing or dying when growth slows down. They’re resting, and that’s exactly what they should be doing.
Do I need to water my plants differently in winter?
Yes. Plants use way less water in winter because they grow slower. Check the soil with your finger before watering. Only water when the top inch feels dry. Most plants need water once every 2-3 weeks instead of weekly.
Why are my plant leaves getting crispy in winter?
Your home’s heating system is drying out the air. Most indoor plants like humidity between 40-60%. Mist your plants 2-3 times a week, group them together, or use a humidifier to add moisture back. Your leaves will bounce back once humidity rises.
Should I move my plants away from windows in winter?
Yes, if the windows are letting in cold drafts. The temperature shock from cold glass hurts plants more than reduced light. Move plants a few feet back from windows, or keep them close but protected with a sheer curtain between the plant and the glass.
Can I fertilize my plants in winter?
No, not really. Most plants rest in winter and don’t need feeding. Skip fertilizing or cut it way back to once a month. Feeding a dormant plant wastes fertilizer and can damage roots. Wait until spring when you see new growth to resume your normal feeding schedule.
