If you’ve been staring at your once-lush pothos and wondering why those vibrant green leaves are now looking a sad shade of yellow, you’re not alone. Pothos leaves turning yellow is one of the most common concerns plant parents face, and the good news is that, in most cases, it’s completely fixable.Â
Whether you’ve had your plant for years or just brought it home last week, this guide will walk you through every possible cause and exactly what to do about it.
How to Identify and Treat the 10 Most Common Houseplant Pests
Why Pothos Leaves Turn Yellow
Pothos (Epipremnum aureum) are famously resilient houseplants, but even they have limits. When something is off in their environment, such as too much water, too little light, or a pest infestation, they communicate that stress through their leaves. Yellow leaves are essentially your plant waving a flag and saying, “Hey, something isn’t right.”
The tricky part is that several different issues can produce the same yellowing symptom. So instead of guessing, let’s go through each cause one by one.
1. Overwatering
Overwatering is by far the number one reason pothos leaves turn yellow. When the soil stays too wet for too long, the roots are deprived of oxygen and begin to rot. A rotting root system can’t deliver nutrients to the rest of the plant, and the leaves start to yellow and wilt as a result.
How to tell if you’re overwatering:
- Soil feels soggy or waterlogged days after watering
- Leaves are yellowing across the whole plant, not just the bottom
- You notice a musty or sour smell coming from the soil
- The pot feels very heavy even when you haven’t watered recently
The fix: Let the soil dry out completely before watering again. Going forward, only water when the top 2 inches of soil feel dry to the touch. If root rot has set in, you may need to repot your plant into fresh, well-draining soil and trim any brown, mushy roots.

2. Underwatering
On the flip side, letting your pothos dry out for too long can also cause yellow leaves. When the plant is severely dehydrated, it starts shedding leaves to conserve energy, and those leaves often turn yellow before they drop.
Unlike overwatering, an underwatered pothos will have dry, crispy soil and leaves that look wilted and pale rather than soft and limp. The fix here is simple: give your plant a thorough watering and make sure the water drains out from the bottom of the pot.

3. Too Much or Too Little Light
Pothos are adaptable when it comes to light, but extremes on either end of the spectrum can cause yellow leaves. Too much direct sunlight can scorch the leaves, causing them to turn yellow with brown, crispy edges. On the other hand, very low light slows down the plant’s ability to photosynthesize, which can gradually cause leaves to yellow and drop.
The fix: Move your pothos to a spot with bright, indirect light. Near a window with filtered sunlight is ideal. Avoid placing it in direct afternoon sun or in a room with no natural light at all.

4. Nutrient Deficiency
If your pothos has been living in the same pot with the same soil for a long time, it may have used up all the available nutrients. A lack of nitrogen in particular causes older leaves (usually at the bottom of the plant) to turn yellow first.
The fix: Feed your pothos with a balanced liquid fertilizer (such as a 10-10-10 formula) every four to six weeks during the spring and summer growing season. Avoid over-fertilizing, as this can cause salt buildup in the soil, which creates its own problems.
5. Being Root Bound
When a pothos outgrows its pot, its roots become tightly packed and have nowhere to expand. This limits the plant’s ability to absorb water and nutrients, which leads to yellow leaves and stunted growth. You’ll know your plant is root bound if you can see roots circling the bottom of the pot or poking out of the drainage holes.
The fix: Repot your pothos into a container that is one to two inches larger in diameter than the current one, using fresh potting mix. The best time to repot is in spring or early summer.

6. Pest Infestations
Common houseplant pests like spider mites, mealybugs, and scale insects can suck the sap from your pothos, causing yellow, speckled, or distorted leaves. Check the undersides of leaves and along stems for tiny bugs, webbing, or sticky residue.
The fix: Isolate the affected plant immediately to prevent the pests from spreading. Treat with neem oil, insecticidal soap, or a gentle wipe-down with rubbing alcohol on a cotton swab. Repeat every week until the pests are gone.

7. Natural Aging: Sometimes It Is Normal
Not all yellow leaves are a cause for alarm. Pothos naturally shed their oldest leaves (typically at the base of the plant) as new growth emerges. If you notice just one or two yellow leaves at the bottom of the plant and the rest looks healthy, your pothos is probably just going through its normal life cycle.
The fix: Simply trim off the yellow leaves to keep your plant looking tidy. No further action is needed.
Quick Diagnosis Guide
Use this table to quickly identify what’s causing your pothos leaves to turn yellow:
| Symptom | Likely Cause | Quick Fix |
|---|---|---|
| Yellow + soggy soil | Overwatering | Let dry out, check drainage |
| Yellow + dry/crispy soil | Underwatering | Water thoroughly |
| Yellow with brown edges | Too much sun | Move to indirect light |
| Bottom leaves only yellow | Natural aging or nutrients | Fertilize or trim |
| Speckled yellow leaves | Pests | Apply neem oil or soap |
| Slow growth + yellow | Root bound | Repot into larger pot |
Frequently Asked Questions
Should I cut off yellow pothos leaves?
Yes, it’s a good idea to remove yellow leaves as soon as you notice them. Yellow leaves won’t turn green again, and leaving them on the plant can sometimes encourage mold or attract pests. Use clean scissors or pruning shears and cut the leaf off at the stem.
Why are my pothos leaves turning yellow and falling off?
If leaves are turning yellow and dropping off, the most likely cause is overwatering or root rot. However, it could also be a sign of a serious pest infestation or dramatic temperature fluctuations. Check the roots for rot and inspect the leaves for bugs to narrow down the cause.
Can yellow pothos leaves turn green again?
Unfortunately, no. Once a leaf turns yellow, the chlorophyll in that leaf has broken down and it won’t recover. Your best move is to remove the yellow leaves and focus your energy on fixing the underlying issue so new, healthy green leaves can grow in their place.
How often should I water my pothos to prevent yellow leaves?
There’s no one-size-fits-all answer because it depends on your home’s humidity, temperature, and the size of your pot. A good general rule is to water every 1 to 2 weeks, but always check the soil first. If the top 2 inches are still moist, wait a few more days. When in doubt, underwater rather than overwater.
Why are the new leaves on my pothos turning yellow?
When new leaves are yellowing rather than old ones, it often points to a nutrient deficiency, particularly a lack of iron or magnesium. It can also be caused by overwatering that has led to root damage, preventing the plant from taking up nutrients even if they’re present in the soil.
