Pothos (Epipremnum aureum) has a reputation as the houseplant that simply refuses to die, which is exactly why a sudden rash of yellow leaves feels so alarming. If the plant the internet promised was unkillable is now dropping soft, yellowing foliage, something in its routine has slipped out of balance. The reassuring news is that yellowing leaves, or chlorosis, are a clear diagnostic signal rather than a death sentence, and pothos is forgiving enough that most cases reverse once you identify the cause. The trick is reading the pattern: which leaves are yellowing, how fast, whether they are firm or mushy, and what the soil and roots are doing. In this guide we walk through the six most common reasons pothos leaves turn yellow, how to tell them apart, and exactly how to fix each one. By the end you will be able to look at your plant and know whether you are dealing with overwatering, a thirsty pot, a dark corner, hungry roots, pests, or simply an old leaf reaching the end of its life.
Key Takeaways
- Overwatering is by far the most common cause of yellow pothos leaves; soggy soil suffocates roots and triggers rot, producing soft yellow leaves and a sour-smelling pot.
- Let the top 1 to 2 inches of soil dry out before watering, always use a pot with drainage holes, and never leave the plant sitting in a full saucer.
- Too little light makes the whole plant pale and leggy, while harsh direct sun bleaches and yellows leaves; bright indirect light is the sweet spot.
- A single yellow lower leaf on an otherwise healthy plant is usually normal aging, not a problem; widespread or rapid yellowing signals a care issue.
- Check for nutrient deficiency, spider mites and root-bound roots if watering and light are dialed in but yellowing continues.
Cause 1: Overwatering and Root Rot
If your pothos is yellowing, start here, because overwatering is responsible for more yellow pothos leaves than every other cause combined. Pothos roots need oxygen as much as they need water, and when soil stays saturated the air pockets between soil particles fill with water and the roots effectively drown. Starved of oxygen, root tissue begins to die and rot, and rotting roots can no longer move water and nutrients up into the plant. The cruel irony is that an overwatered pothos often looks like a thirsty one, wilting and yellowing even though the soil is soaked, because the damaged roots cannot deliver the water that is sitting right there. Left unchecked, root rot spreads and can kill an otherwise vigorous plant within a couple of weeks.
How to diagnose it. Overwatered leaves turn yellow and feel soft, limp, or mushy rather than dry. The yellowing usually starts with the lower and innermost leaves and the soil stays wet for days. Lift the pot: if it feels heavy and the soil surface is damp or smells sour and swampy, water is the problem. Slide the plant out and inspect the roots. Healthy pothos roots are firm and white or pale tan; rotting roots are brown or black, soft, and may smell foul or slide apart between your fingers.
How to fix it. Stop watering immediately and let the soil dry out. If you find rot, remove the plant from its pot, rinse the roots, and trim away every mushy brown root with clean scissors, keeping only firm pale tissue. Repot into fresh, well-draining potting mix in a clean pot that has drainage holes, sized so it is not drastically larger than the root ball. Going forward, water only when the top 1 to 2 inches of soil are dry to the touch, water thoroughly until it drains from the bottom, and then empty the saucer so the roots never sit in standing water. A chronically overwatered pothos also benefits from a chunkier mix amended with perlite; our guide on perlite versus vermiculite explains how each affects drainage and aeration.
Cause 2: Underwatering and Drought Stress
Pothos tolerates a missed watering far better than a flooded one, but push it too far and it will yellow from thirst. When soil dries out completely for an extended stretch, the plant cannot pull up the moisture its leaves are losing to the air, so it begins shedding foliage to conserve water. The oldest leaves are sacrificed first, yellowing and then crisping as the plant redirects its limited resources to newer growth. This is a slower, drier decline than the soft collapse of overwatering, and it is common in people who, having heard that pothos is drought-tolerant, simply forget about it for weeks at a time or keep it in a tiny pot that dries out almost instantly.
How to diagnose it. Underwatered yellow leaves feel dry, thin, and papery rather than mushy, and the browning often follows the yellow, starting at the edges and tips. The soil will be bone dry, sometimes pulling away from the sides of the pot, and the whole plant may look limp and droopy with curling leaves. If you cannot remember the last time you watered and the pot feels feather-light, drought stress is the likely answer.
How to fix it. Rehydrate gradually. If the soil has dried into a hard mass that water runs straight through, bottom-water the plant by setting the pot in a tray of water for 20 to 30 minutes so the soil can soak it up evenly, or submerge the whole pot until air bubbles stop rising. Then let it drain fully. Once recovered, settle into a consistent routine of checking the soil with your finger and watering when the top inch or two has dried. A pothos in a small pot or a warm, bright room will need water more often, so adjust by feel rather than a rigid calendar. Drooping leaves usually perk back up within a day, though leaves that have already yellowed will not green up again.
Cause 3: Too Little or Too Much Light
Pothos is marketed as a low-light plant, and it will survive in a dim corner, but survive is not the same as thrive. In too little light the plant cannot photosynthesize enough to support all its foliage, so older leaves yellow and drop, growth becomes leggy with long bare stretches of stem between leaves, and any variegation fades toward plain green as the plant tries to maximize its chlorophyll. At the other extreme, pothos placed in harsh, direct sunlight suffers leaf scorch: the intense rays bleach and yellow the foliage, often with brown crispy patches where the tissue has burned. Light, then, causes yellowing at both ends of the spectrum.
How to diagnose it. If your pothos sits in a dark room or far from any window, and the yellowing comes with sparse, stretched-out, fading growth, it needs more light. If instead it sits in a south or west window where the sun beats directly on the leaves, and the yellow or bleached patches appear on the most sun-exposed side, it is getting too much. Variegated varieties like marble queen and golden pothos are especially telling: when they revert to solid green, they are reaching for more light.
How to fix it. Aim for bright, indirect light, the dappled condition pothos evolved under as a forest-floor climber. A spot a few feet back from an east or north-facing window, or beside a brighter window screened by a sheer curtain, is ideal. If your home is genuinely dark, a simple LED grow light keeps the plant healthy and preserves variegation. Move a scorched plant out of direct sun straight away. Rotate the pot a quarter turn each week so all sides receive even light and the plant grows symmetrically rather than leaning and yellowing on one face.
Cause 4: Nutrient Deficiency
Potting mix is not an infinite pantry. Every time you water, a little of the available nutrition leaches out the drainage holes, and after a year or two in the same soil a pothos can simply run out of the nitrogen, magnesium, and iron it needs to keep its leaves green. Because chlorophyll production depends on these nutrients, a deficiency shows up as yellowing, but the pattern differs by nutrient. A nitrogen shortage yellows the oldest leaves first, since the plant moves this mobile nutrient to its newest growth. Iron and magnesium deficiencies, by contrast, tend to yellow the newer leaves while the veins stay green, a distinctive look called interveinal chlorosis.
How to diagnose it. Suspect a deficiency when watering and light are dialed in, the plant has been in the same soil for a long time, and you have never fertilized it. Look at the pattern: uniform yellowing of older leaves points to nitrogen, while yellow leaves with a clear green vein network point to iron or magnesium. The growth often slows and any new leaves emerge smaller and paler than they should.
How to fix it. Feed the plant during the growing season. A balanced liquid houseplant fertilizer diluted to half strength, applied roughly once a month from spring through early autumn, restores the missing nutrients without risking fertilizer burn. Do not feed in winter when the plant is resting. If the plant has been in the same pot for more than a couple of years, refreshing the top layer of soil or repotting into fresh mix delivers a nutrient reset that liquid feeding alone cannot match. Be careful not to overcorrect, as too much fertilizer leaves a salt buildup that also damages roots. Our overview of liquid versus granular fertilizer can help you pick the right feeding approach for houseplants.
Cause 5: Pests, Especially Spider Mites
Sap-sucking insects are an underappreciated cause of yellow pothos leaves. Spider mites, mealybugs, and scale all feed by piercing the leaf and draining the plant’s juices, and each puncture kills a tiny patch of tissue. Multiply that across a thriving infestation and the leaf takes on a stippled, speckled yellow appearance before fading and dropping. Spider mites are the most common culprit on pothos and the easiest to miss, because they are nearly microscopic and thrive in the warm, dry indoor air of heated homes. By the time you notice the yellowing, a colony may already have spread across several vines.
How to diagnose it. Inspect the undersides of the leaves and the leaf joints closely, ideally with a magnifying glass. Spider mites leave fine webbing in the leaf axils and a dusty, speckled yellow mottling across the leaf surface. Mealybugs look like small tufts of white cotton, and scale appears as small brown bumps along the stems. A quick test for mites is to hold a sheet of white paper under a leaf and tap it; if tiny moving specks fall onto the paper, you have mites.
How to fix it. Isolate the affected plant immediately so the pests do not spread to your other houseplants. Wipe down every leaf, top and bottom, with a cloth, then treat the whole plant thoroughly with insecticidal soap or a diluted neem oil spray, coating the undersides where pests hide. Repeat the treatment every five to seven days for three to four weeks to catch newly hatched insects, since a single application rarely clears an infestation. Raising humidity discourages spider mites specifically, as they favor dry air. Once the pests are gone, the existing yellow leaves will not recover, but new growth will come in clean.
Cause 6: Natural Aging and Other Stressors
Sometimes a yellow leaf is simply a leaf reaching retirement. Pothos continually produces new foliage at the growing tips, and to fund that growth it eventually retires its oldest leaves, withdrawing their nutrients and letting them yellow and fall. This is completely normal and nothing to fix. The key is scale and location: natural aging shows up as the occasional yellow leaf low on the vine or near the soil, on an otherwise green and healthy plant. If only one old leaf yellows every few weeks, relax and pluck it off. Beyond aging, abrupt environmental changes also trigger a wave of yellowing as the plant adjusts.
How to diagnose it. Natural aging is slow, occasional, and confined to the lowest, oldest leaves. By contrast, if a plant has recently been repotted, moved to a new room, exposed to a cold draft from a door or window, or placed near a heating or cooling vent, a flush of yellow leaves often follows as transplant or temperature shock. Cold-damaged leaves may also look slightly translucent or develop dark patches. Being root-bound, where roots circle densely and poke from the drainage holes, is another slow stressor that yellows leaves as the plant outgrows its pot.
How to fix it. For ordinary aging, simply remove the spent leaves to keep the plant tidy; no other action is needed. For shock, give the plant time and stable conditions to recover rather than reacting with more water or fertilizer, which usually makes things worse. Keep pothos in a steady 65 to 85°F range and away from cold drafts and hot vents, both of which it dislikes. If the plant is root-bound, repot it in spring into a container one size larger with fresh mix.

How to Prevent Yellow Pothos Leaves
Prevention comes down to consistency in the handful of variables pothos actually cares about. Water by feel, not by calendar: push a finger into the soil and water only when the top inch or two has dried, then water thoroughly and tip out the saucer so the roots never stew in water. This single habit prevents the overwatering and root rot that cause most yellow leaves. Pair it with a pot that has drainage holes and a free-draining mix, and you have removed the biggest risk entirely.
Place the plant in bright indirect light, out of both gloomy corners and scorching direct sun, and rotate it weekly for even growth. Feed monthly with half-strength fertilizer through spring and summer, refresh the soil every couple of years, and inspect the undersides of leaves now and then so you catch pests before they spread. Keep the temperature steady and the plant away from drafts and vents. Do these things and the occasional yellow leaf low on the vine is nothing to worry about; it is just an old leaf making way for new growth on a plant that, true to its reputation, is very hard to kill.
Frequently Asked Questions
Should I remove yellow leaves from my pothos?
Yes. A yellow leaf will not turn green again, so removing it improves the plant’s appearance and lets it redirect energy to healthy growth. Pinch or snip it off at the base with clean scissors. Just remember that pulling off the leaf treats the symptom, so identify and fix the underlying cause too.
How do I know if my pothos is overwatered or underwatered?
Feel the leaves and the soil. Overwatered pothos has soft, limp, mushy yellow leaves and wet, sour-smelling soil. Underwatered pothos has dry, papery yellow leaves with crisp brown edges and bone-dry soil that may pull from the pot. Checking whether the soil is soggy or bone dry is the fastest way to tell them apart.
Is it normal for pothos to have a few yellow leaves?
Yes. Pothos naturally retires its oldest leaves to fund new growth, so an occasional yellow leaf low on the vine on an otherwise healthy, green plant is normal aging. Concern is warranted only when yellowing is widespread, rapid, or affecting newer leaves, which points to a care problem rather than ordinary aging.
How often should I water a pothos?
Water when the top 1 to 2 inches of soil have dried out rather than on a fixed schedule. Depending on light, warmth, and pot size, that usually falls every 7 to 14 days. Always water thoroughly until it drains from the bottom, then empty the saucer so the roots are never left sitting in standing water.
Can a pothos recover from yellowing leaves?
The plant can recover, but the individual yellow leaves cannot turn green again. Once you fix the cause, whether overwatering, light, nutrients, or pests, the existing yellow leaves should be removed and the plant will put out healthy new growth. As long as the roots and stems are still firm and alive, the plant itself bounces back well.
