Pothos can absolutely survive winter, but you need to change how you care for them when temperatures drop.
Keeping pothos alive in winter is all about mimicking the plant’s natural dormancy period without shocking it.
Indoor conditions like shorter days, drier air, and cooler windowsills can stress your pothos if you don’t adjust.
But with a few simple tweaks, you can keep pothos alive in winter and even see some steady growth through the cold months.
In this post we’ll cover the exact steps to keep pothos alive in winter, what mistakes to avoid, and how to revive a struggling plant.
Let’s dig in.
Why Adjusting Care Helps Keep Pothos Alive in Winter
Your pothos enters a slower growth phase during winter because light intensity and day length decrease.
To keep pothos alive in winter, you need to scale back watering, stop fertilizing, and provide the best light possible.
Here’s why each adjustment matters for keeping pothos alive during winter.
1. Less Light Means Less Water Needed
In winter, your pothos doesn’t photosynthesize as actively as it does in summer.
That means the soil stays wet longer because the plant isn’t drinking as much.
Overwatering is the number one reason people fail to keep pothos alive in winter.
Checking the soil with your finger before watering is the best way to avoid root rot.
Only water when the top two inches of soil feel completely dry.
2. Cooler Temperatures Slow Metabolism
Pothos prefer temperatures between 65–85°F, and they struggle below 50°F.
To keep pothos alive in winter, keep them away from drafty windows, doors, or heat vents.
Cold drafts cause leaf yellowing and drop, while hot air from vents dries them out too fast.
A steady room temperature around 65–75°F is ideal for keeping pothos alive through winter.
3. Low Humidity Demands a Boost
Indoor winter air is dry from heaters, and pothos love humidity.
Brown leaf edges or curling leaves are signs your pothos isn’t happy.
To keep pothos alive in winter, increase humidity with a pebble tray, a small humidifier, or by grouping plants together.
Misting helps temporarily, but it isn’t enough to raise humidity long-term.
Essential Steps to Keep Pothos Alive in Winter
Now that you understand the “why,” let’s look at the practical how.
These five steps will help you keep pothos alive in winter without guesswork.
1. Provide Bright Indirect Light
Move your pothos to the brightest window you have, preferably south or east facing.
Pothos can survive in low light, but they won’t thrive, and winter already gives less light.
If you can’t provide enough natural light, use a grow light for 10–12 hours a day.
This simple change makes a huge difference in keeping pothos alive in winter.
2. Water Less Frequently
Reduce watering to every 2–3 weeks depending on your home’s dryness.
Always let excess water drain out, never let the pot sit in standing water.
Using a moisture meter can take the guesswork out of watering for keeping pothos alive during winter.
3. Stop Fertilizing Until Spring
Pothos don’t need extra nutrients when growth slows.
Fertilizing in winter can burn the roots because the plant isn’t using them.
Resume feeding in March or April when you see new growth again.
4. Keep Them Away from Drafts and Vents
Cold windows and hot air currents stress pothos quickly.
Place your plant on a shelf or table away from exterior doors, drafty windows, and heating vents.
A consistent environment is key to keeping pothos alive in winter.
5. Clean the Leaves Periodically
Dust blocks light absorption, which is critical during dark winter months.
Gently wipe each leaf with a damp cloth every few weeks.
This simple act helps your pothos make the most of the limited winter light.
Common Mistakes That Prevent You from Keeping Pothos Alive in Winter
Even experienced plant parents slip up in winter.
Avoid these three pitfalls to keep pothos alive in winter successfully.
1. Overwatering Out of Habit
It’s tempting to water on a schedule, but pothos need much less in winter.
Yellowing leaves and mushy stems are early signs of overwatering.
If you see these, let the soil dry out completely before watering again.
2. Placing the Plant Too Close to a Cold Window
Even a few inches can make a difference.
Pothos leaves touching a cold glass pane will develop black spots and die back.
Pull your plant back at least a foot from the window on frigid nights.
3. Ignoring Pests in a Stressed Plant
Winter-weakened pothos are more susceptible to spider mites and mealybugs.
Check the undersides of leaves weekly if you want to keep pothos alive in winter.
Catch pests early and treat with neem oil or insecticidal soap.
So, How to Keep Pothos Alive in Winter?
The best way to keep pothos alive in winter is to adjust your watering, light, and environment to match the season.
Less water, more light, stable temperatures, and higher humidity will keep pothos alive in winter without much fuss.
Avoid overwatering, cold drafts, and neglect, and your pothos will sail through winter into spring.
With these tips, keeping pothos alive in winter becomes simple and stress-free.
