Why Your Pothos Leaves Are Turning Yellow (And What I Did to Fix Mine)

I've killed more pothos plants than I'd like to admit before finally figuring out what I was doing wrong. For a plant that's supposed to be impossible to kill, those yellow leaves kept appearing and honestly made me question my entire ability to keep anything alive. After a lot of trial and error (and yes, some panicked Googling at 11 PM), I've learned that yellow leaves aren't a death sentence—they're just your pothos trying to tell you something. Here's what I've figured out through my own mistakes.

Overwatering: The Most Common Culprit

This was my biggest problem. I thought being a good plant parent meant watering on a strict schedule, so every Sunday like clockwork, I'd water my pothos. Turns out, that's exactly what was killing it. Pothos roots absolutely hate sitting in soggy soil, and overwatering leads to root rot, which shows up as yellow leaves. Now I stick my finger about two inches into the soil—if it's still moist, I wait. My pothos has been way happier since I started letting the top half of the soil dry out between waterings. If you've been watering on a schedule rather than checking the soil, this is probably your issue too. The fix is simple: let it dry out more and make sure your pot has drainage holes.

Not Enough Light (Or Too Much)

I had my pothos in what I thought was a nice dim corner because I'd read they tolerate low light. They do tolerate it, but they don't exactly thrive in it. When leaves started yellowing from the bottom up, I moved it closer to a window with bright, indirect light, and the new growth came in so much healthier. On the flip side, my sister had hers in direct afternoon sun and got yellowing with brown crispy edges—that's sunburn. Pothos want that sweet spot of bright but filtered light. I keep mine about 6 feet from an east-facing window now, and it's perfect. If your whole plant is looking pale and yellow, try more light. If just the sun-facing leaves are yellow and crispy, move it back from the window.

Nutrient Deficiency and When to Fertilize

Here's something I didn't realize for way too long: pothos actually need food. If your plant is in the same soil it came in from the store and you've never fertilized, yellowing leaves (especially older ones) might mean it's run out of nutrients. I now use a diluted liquid fertilizer once a month during spring and summer, and maybe once every two months in winter when growth slows down. I use half the strength the bottle recommends because I learned the hard way that too much fertilizer causes brown tips and can also make leaves yellow. If you haven't fertilized in over a year and the yellowing is mainly on older, lower leaves while new growth looks okay, try adding some food. Just don't overdo it like I did the first time.

Normal Aging vs. Actual Problems

This one took me forever to accept: sometimes a yellow leaf is just an old leaf. If you've got one or two lower leaves turning yellow while the rest of the plant looks great and you're seeing new growth, that's probably just the plant shedding old foliage. It's completely normal. I used to panic every single time, but now I just trim off the yellow leaf and move on with my life. The difference between normal aging and a real problem is the pattern—one or two old leaves at the bottom is fine, but multiple leaves yellowing rapidly or new growth coming in yellow means something's actually wrong. Don't be like me and repot your entire plant because of one yellow leaf. Check everything else first, and if the plant otherwise seems happy, it's probably just doing its thing.
