Why Is My Monstera Turning Yellow in Winter? Fix It Fast
Discovering yellow leaves on your Monstera during winter can be alarming, but it's one of the most common cold-season plant problems. Learn the real reasons it happens and exactly how to fix it.
Why Is My Monstera Turning Yellow in Winter?
You've been nurturing your Monstera all year, and then winter rolls in and suddenly those gorgeous green leaves start fading to yellow. Don't panic — you're not alone, and your plant almost certainly isn't dying. Winter is actually the most common time for Monstera owners to notice yellowing leaves, and the good news is that most causes are completely fixable once you know what to look for.
Let's walk through every likely reason your Monstera is turning yellow in winter, so you can diagnose the problem and get your plant thriving again.
The Most Common Reasons for Yellow Monstera Leaves in Winter
1. Overwatering — The #1 Winter Culprit
This is, by far, the most frequent cause of yellow Monstera leaves during the colder months. Here's the thing: your Monstera's growth slows dramatically in winter, which means it needs significantly less water than it did in spring and summer.
If you're still watering on the same schedule you used in July, you're almost certainly overwatering. Excess moisture in the soil suffocates the roots, prevents oxygen from reaching them, and leads to root rot — all of which show up first as yellowing leaves.
What to do: Stick your finger 2–3 inches into the soil. If it still feels damp, wait. In winter, most Monsteras only need watering every 10–14 days, sometimes even less depending on your home environment. Always let the top half of the soil dry out before watering again.
2. Reduced Light Levels
Winter means shorter days, lower sun angles, and weaker light intensity — even if your Monstera is sitting in the same spot it always has been. What was once a bright indirect light location in summer might now be receiving barely enough light to sustain healthy growth.
When a Monstera doesn't get enough light, it can't photosynthesize efficiently, and older leaves will often turn yellow as the plant redirects its limited energy toward newer growth.
What to do: Move your Monstera closer to your brightest window — ideally one that faces south or east. Clean any dusty window glass to maximize light transmission. If natural light is genuinely limited in your space, consider adding a grow light for 8–10 hours per day. Even a basic LED grow light can make a remarkable difference through the winter months.
3. Cold Drafts and Temperature Stress
Monsteras are tropical plants that thrive between 65–85°F (18–29°C). In winter, cold drafts from windows, doors, or air vents can expose your plant to sudden temperature drops that cause stress — and stress often shows up as yellow leaves.
What to do: Check where your Monstera is positioned. Is it near a drafty window or an exterior door that gets opened frequently? Move it at least a foot or two away from any cold glass surfaces or vents. Use a thermometer near your plant to make sure the temperature stays consistently above 60°F (15°C).
4. Low Humidity
Winter heating systems are notorious for drying out indoor air, and Monsteras — being native to tropical rainforests — really do feel that drop in humidity. When the air gets too dry, leaves can yellow at the edges and tips before spreading further.
What to do: Aim to keep humidity above 50% around your Monstera. You can boost humidity by:
- Using a humidifier nearby (the most effective option)
- Grouping your plants together to create a microclimate
- Placing a tray of pebbles and water beneath the pot
- Misting leaves occasionally, though this is a short-term fix
5. Nutrient Deficiency
Most people stop fertilizing in winter, which is correct — but if your Monstera was already low on nutrients heading into the cold season, yellowing leaves can be a sign of deficiency. Nitrogen deficiency in particular causes older, lower leaves to turn uniformly yellow.
What to do: Avoid heavy feeding in winter, as it can stress a plant that's already in a slower growth phase. However, if you haven't fertilized since summer, one light application of a balanced liquid balanced liquid fertilizer (diluted to half strength) in early winter can help without overwhelming the plant. Resume a regular feeding schedule in spring when growth picks up again.
6. Root Rot From Soggy Soil
If your Monstera has been sitting in wet soil for an extended period, root rot may have already set in. Rotting roots cannot transport water or nutrients to the leaves, which causes them to yellow and eventually die off.
What to do: Gently remove your plant from its pot and inspect the roots. Healthy roots are white or light tan and firm. Rotted roots are dark brown or black and mushy. Trim away any rotted sections with clean scissors, dust the cuts with cinnamon or activated charcoal (natural antifungals), and repot in fresh, well-draining soil. Make sure your pot has pots with drainage holes.
How to Tell Which Problem You're Dealing With
The pattern of yellowing can give you helpful clues:
- Older, lower leaves yellowing first: Usually overwatering or nutrient deficiency
- Yellow with brown crispy edges: Low humidity or cold draft stress
- Pale, washed-out yellow across the whole plant: Insufficient light
- Yellow with mushy stems or a bad smell: Root rot — act immediately
Winter Monstera Care Checklist
Use this quick checklist every few weeks through winter to keep your Monstera healthy:
- Check soil moisture before every watering — when in doubt, wait
- Ensure your plant is receiving at least 4–6 hours of bright indirect light daily
- Keep temperatures consistently above 60°F and away from drafts
- Monitor humidity levels and use a humidifier if your home is dry
- Inspect leaves and stems for any signs of pests, which can also cause yellowing
- Only fertilize lightly, if at all, until spring returns
Should You Remove Yellow Leaves?
Yes — once a leaf has turned fully yellow, it won't recover its green color. Removing yellow leaves keeps your plant looking its best and prevents any potential spread of disease. Use clean, sharp scissors or pruning shears and cut at the base of the leaf stem. After pruning, focus your energy on improving the underlying care conditions so new leaves grow in healthy and green.
When to Worry (And When Not To)
One or two yellow leaves in winter? Completely normal. Monsteras naturally shed older leaves as part of their growth cycle, and this tends to happen more visibly in winter when the plant is conserving energy. If multiple leaves across the plant are yellowing rapidly, that's your signal to investigate more urgently — especially for root rot.
With a few adjustments to your watering habits, light setup, and humidity levels, most Monsteras bounce back beautifully as spring approaches.

Frequently Asked Questions
Why is my Monstera turning yellow in winter?
The most common causes are overwatering, reduced light levels, cold drafts, and low humidity. Winter slows Monstera growth, making the plant more sensitive to these environmental changes.
How often should I water my Monstera in winter?
Water every 10–14 days in winter, or less frequently depending on your home environment. Always let the top half of the soil dry out before watering again.
Does low light cause Monstera leaves to turn yellow?
Yes, insufficient winter light prevents efficient photosynthesis, causing older leaves to yellow as the plant redirects energy to newer growth. Moving the plant closer to a south- or east-facing window or adding a grow light for 8–10 hours daily can help.
Can cold drafts cause yellow leaves on a Monstera?
Yes, Monsteras are tropical plants that need temperatures between 65–85°F, and cold drafts from windows or vents cause stress that shows up as yellowing leaves. Keep your plant at least a foot away from cold glass and ensure temperatures stay above 60°F.
Is my Monstera dying if its leaves turn yellow in winter?
Almost certainly not — winter yellowing is very common and usually caused by fixable issues like overwatering or low light. Most Monsteras recover once the underlying cause is addressed.
