Why Are My Pothos Leaves Turning Yellow?
Yellow pothos leaves usually mean overwatering, not a death sentence. A yellow leaf won't turn green again, so the goal is stopping the next one. Here is how to tell overwatering from underwatering, light, aging, and nutrient issues, and how to fix each.
The first plant I ever killed was a pothos, which is a little embarrassing because pothos are supposed to be unkillable. I watered it every Sunday like clockwork because a watering schedule felt responsible. By week three the leaves were going yellow from the bottom up, so I assumed it was thirsty and watered it more. That was exactly the wrong move.
If you're looking at a yellow pothos leaf and trying to work out whether you're under- or over-loving your plant, that's the right question. Yellowing (the technical word is chlorosis) is a pothos's most common distress signal, and it points to five different things depending on the pattern. The good news: a yellow leaf or two is almost never an emergency. Let's figure out which one you've got.
First, the leaf you can't save
A yellow pothos leaf does not turn green again. Once a leaf loses its chlorophyll, that's permanent, so the goal isn't to rescue the yellow leaf in front of you. It's to stop the next one from going. Pinch off the fully yellow ones at the base if they bother you, since the plant has already pulled the useful nutrients out of them, and focus on the cause.
Cause 1: Overwatering (the most likely culprit)
If I had to bet, this is your problem. It's the most common reason pothos go yellow, and it's the one I fell for. Here's what overwatering looks like on a pothos:
- Yellowing starts on the lower and older leaves first
- The yellow leaves feel soft or limp, not crispy
- The soil is still damp days after you watered
- You might notice a few mushy brown spots, or a faint musty smell from the pot
The mechanism is a little counterintuitive. Pothos roots need air as much as they need water. When soil stays saturated, the roots can't breathe, they start to rot, and a rotting root system can't move water up to the leaves. So an overwatered plant often looks exactly like a thirsty one: droopy and yellow. That's the trap I walked into.
The fix: stop watering on a schedule. Water when the top inch or two of soil is dry to the touch, not when the calendar says Sunday. Stick your finger in the pot; if it comes out with damp soil clinging to it, wait. For most pothos in an average apartment that lands somewhere around once a week to once every ten days, but the pot, the light, and the season all change that number, which is exactly why the schedule fails.
The number one beginner mistake: a pothos in a cute pot with no drainage hole. Without drainage the roots sit in water and rot. If your pot can't drain, that's the first thing to change, before anything else.
Cause 2: Underwatering
Less common, but it happens, especially to people who overcorrect after reading something like this. Underwatered pothos look different:
- Leaves go yellow but also feel dry, thin, or crispy at the edges
- The whole plant looks limp and deflated, then perks up dramatically after a drink
- The soil is bone dry and may have pulled away from the sides of the pot
If the soil is so dry that water runs straight through without soaking in, bottom-water it: set the pot in a few inches of water for 20 to 30 minutes and let it drink from below, then go back to checking with your finger. The tell between over and under is the texture of the yellow leaf. Soft and limp leans overwatered. Dry and crispy leans underwatered.
Cause 3: Light (too much or too little)
Pothos are famously low-light tolerant, but "tolerant" isn't the same as "thriving." Too little light slows everything down: the plant grows leggy with big gaps between leaves and can shed lower leaves (yellowing them first) because it can't support them. If your pothos is in a genuinely dim corner and dropping leaves, move it somewhere brighter, near but not in a window.
Too much direct sun does the opposite. Harsh afternoon light scorches pothos leaves, bleaching them to a pale yellow or leaving crispy brown patches. Pothos want bright, indirect light: an east-facing window, or a few feet back from a south or west one. If your pothos is healthy but just wants an easier spot, it's one of the plants I point beginners to in our low-light houseplants collection, precisely because it forgives a dim room better than almost anything else.
Cause 4: Natural aging
Sometimes a yellow leaf is just a plant being a plant. Pothos push new growth at the vine tips and let go of their oldest leaves to redirect energy. If you're seeing one occasional yellow leaf, low down on an otherwise full and healthy vine, and the new growth up top looks great, that's normal aging. Pinch it off and move on. The pattern that should worry you is multiple leaves yellowing at once, or yellowing creeping up toward the newer growth.
Cause 5: Nutrient deficiency
This one's last because it's the least likely for a plant you've had under a year, but it's real. If your pothos has been in the same pot for a couple of years and you've never fed it, the soil may be tapped out. Nutrient-related yellowing often shows up as interveinal chlorosis, where the leaf goes yellow but the veins stay green, giving it a marbled look. A balanced houseplant fertilizer diluted to half strength, applied in spring and summer, usually sorts it out. Don't overdo it: salt buildup from over-feeding causes its own brown leaf tips. If it's been a couple of years in the same pot, repotting into fresh soil one size up does the same job and gives the roots room.
A quick diagnostic, leaf in hand
Run through this in order:
- Poke the soil. Wet days after watering? Overwatering (Cause 1). Bone dry with crispy leaves? Underwatering (Cause 2).
- Feel the yellow leaf. Soft and limp points to water at the roots. Dry and papery points to thirst or sun.
- Check where it's yellowing. Bottom and old leaves, slow and occasional, is usually normal aging or mild overwatering. New growth yellowing is a real problem.
- Look at the light. Dim corner with leggy growth, or scorched pale patches from direct sun? Move it.
- Count the candles. Same pot for two-plus years, never fed, veins staying green? Feed or repot.
Nine times out of ten with a beginner pothos, you'll land on number one. Ease off the water and the plant usually stabilizes within a couple of weeks.
If you want to start fresh
If yours is too far gone (mushy stems, rot through most of the root ball), don't beat yourself up. The reason pothos is the plant I recommend to every nervous first-timer is that it's almost impossible to kill once you've made the one watering mistake everybody makes.

Whatever you do, throw out the watering schedule. Your finger is a better moisture meter than the calendar.

Will a yellow pothos leaf turn green again?
No. Once a leaf loses its chlorophyll and yellows, that change is permanent. Pinch off fully yellow leaves at the base and focus on fixing the cause so the next leaf stays green.
How often should I water a pothos?
Water when the top inch or two of soil is dry, not on a fixed schedule. For most pothos that works out to roughly once a week to once every ten days, but light, pot size, and season all shift it. Check with your finger every time instead of trusting the calendar.
Should I cut off the yellow leaves?
You can. The plant has already reclaimed the useful nutrients from a fully yellow leaf, so pinching it off at the base doesn't hurt the plant and tidies up the look. The important part is diagnosing why it yellowed so it doesn't keep happening.
