Why Is My Pothos Turning Yellow? 7 Common Causes and Fixes

Why Are My Pothos Leaves Turning Yellow?

Pothos (Epipremnum aureum) has a well-earned reputation as one of the most forgiving houseplants you can own. It tolerates low light, occasional neglect, and imperfect conditions better than almost anything else on a windowsill. So when you notice your pothos turning yellow, it's natural to feel a little alarmed — or even personally offended. The good news is that yellow leaves are almost always a signal, not a death sentence. Once you identify the cause, the fix is usually straightforward. Here are the seven most common reasons your pothos leaves are turning yellow, and exactly what to do about each one.

The 7 Most Common Causes of Yellow Pothos Leaves

1. Overwatering

Overwatering is the single most common cause of yellow pothos leaves, and it's also the most misunderstood. The problem isn't really the water itself — it's what happens when roots stay wet for too long. Waterlogged soil cuts off oxygen to the roots, which leads to root rot, and a rotting root system simply cannot deliver nutrients or water to the rest of the plant. The leaves respond by turning yellow.

Watch for these signs that overwatering is your culprit:

Leaves are yellowing from the bottom up or across multiple areas at once
Soil feels consistently damp or soggy, even days after watering
The pot feels heavy
There's a musty or sour smell coming from the soil
Roots look brown, slimy, or mushy when you check them

Fix: Allow the top 1–2 inches of soil to dry out completely before watering again. Always use a pot with drainage holes — never let your pothos sit in standing water. If you suspect root rot, remove the plant from its pot, rinse the roots gently, and trim away any brown or mushy sections with clean scissors. Repot into fresh, well-draining quality potting mix and resist the urge to water immediately.

2. Underwatering

On the flip side, pothos that go too long without water will also develop yellow leaves, typically accompanied by drooping, crispy leaf edges, and dry, pulling-away-from-the-pot soil. While pothos is drought-tolerant, it's not drought-proof.

Fix: Water your pothos thoroughly — slowly pour water until it runs freely from the drainage holes, which ensures the entire root ball gets moistened. For most homes, pothos need watering every 7–10 days, but always let the soil be your guide rather than the calendar. If the top inch or two of soil is dry, it's time to water.

3. Too Much Direct Sunlight

Pothos are naturally adapted to the dappled light of tropical forest floors, which means they genuinely prefer indirect light. When exposed to harsh, direct sun — especially through a south- or west-facing window — leaves can develop yellow patches, bleached-out spots, or even scorched brown edges.

Fix: Move your plant a few feet back from a bright window, or filter the light with a sheer curtain. North- and east-facing windows tend to work best for pothos. If your home is on the darker side, don't worry — pothos handles low light remarkably well, though growth will be slower.

4. Nutrient Deficiency

Potting soil starts out rich in nutrients, but those nutrients get depleted over time through regular watering. If your pothos has been living in the same soil for more than a year without any balanced liquid fertilizer, a lack of nitrogen or other essential nutrients could be causing older leaves to pale and yellow.

Nitrogen deficiency typically causes uniform yellowing that starts with the oldest (lowest) leaves. Iron or magnesium deficiency, on the other hand, tends to cause yellowing between the leaf veins while the veins themselves stay green — a pattern called interveinal chlorosis.

Fix: Feed your pothos with a balanced liquid fertilizer (such as a 10-10-10 fertilizer or 20-20-20 formula) once a month during spring and summer. Cut back to every 6–8 weeks in fall and winter when growth naturally slows. Never fertilize a dry plant — always water first to avoid burning the roots.

5. Temperature Stress and Cold Drafts

Pothos thrive in temperatures between 65–85°F (18–29°C) and are surprisingly sensitive to sudden temperature changes. Cold drafts from open windows, exterior doors, or air conditioning vents can stress the plant and trigger yellowing, especially during winter months.

To check if temperature is the issue, ask yourself:

Is your pothos near an exterior window that gets cold at night?
Is it sitting directly in the path of an AC or heating vent?
Has it been exposed to temperatures below 50°F (10°C)?

Fix: Relocate your plant to a spot with a more stable temperature. Keep it away from drafty windowsills, exterior doors, and HVAC vents. Avoid placing it on cold concrete floors or against exterior walls in winter.

6. Root Bound

A pothos that has outgrown its pot can develop yellow leaves because tightly packed roots struggle to absorb water and nutrients efficiently, even when you're doing everything else right. Signs that your plant is root bound include roots circling visibly at the bottom of the pot, roots poking out of drainage holes, or soil that dries out extremely quickly after watering.

Fix: Repot your pothos into a container that's 1–2 inches larger in diameter than the current one. Use a high-quality indoor potting mix with good drainage. Spring is the ideal time to repot, but if the plant looks stressed, don't wait. After repotting, water thoroughly and place the plant in indirect light while it adjusts.

7. Natural Aging

Not every yellow leaf is a problem. As pothos grow, they naturally shed their oldest leaves — typically the ones at the very base of the vine — to redirect energy toward new growth. If you notice just one or two yellowing leaves at the bottom of the plant while the rest of the foliage looks lush and healthy, this is completely normal.

Fix: No action required. Simply remove the yellowing leaves by gently pulling them free from the stem, or snipping them off with clean scissors. This keeps your plant looking tidy and prevents any potential for disease.

How to Diagnose Yellow Pothos Leaves Quickly

With so many possible causes, it helps to approach diagnosis systematically. Run through this quick checklist whenever you spot pothos yellow leaves:

Check the soil. Is it soggy, bone dry, or appropriately moist? This rules out over- or underwatering right away.
Look at the pattern. Are leaves yellowing evenly, or just between the veins? Uniform yellowing often points to overwatering or nitrogen deficiency; interveinal yellowing suggests a micronutrient issue.
Note which leaves are affected. Bottom leaves yellowing? Could be natural aging or overwatering. New growth yellowing? More likely a nutrient or light issue.
Assess the location. Is the plant near a vent, drafty window, or in direct sun?
Check the roots. If all else fails, a quick root inspection will confirm or rule out root rot.

When to Take Immediate Action

Most cases of yellow pothos leaves can be resolved with a simple care adjustment. However, there are situations where you should act quickly:

Multiple leaves are yellowing rapidly across the entire plant
The soil smells foul or the roots look dark and mushy
The stems are turning soft or translucent near the soil line
Yellow leaves are also wilting despite moist soil

These signs point to root rot, which can kill a plant if left untreated. Remove the plant from its pot immediately, cut away all damaged roots, let the healthy roots air out for an hour, then repot in fresh, well-draining soil. Hold off on watering for a day or two to give the trimmed roots time to recover.

Summary: Keeping Your Pothos Happy and Green

Yellow leaves are your pothos's way of telling you something is off — but with a little detective work, the cause is almost always identifiable and fixable. The most important habits for preventing pothos yellow leaves in the first place are simple: water only when the top inch of soil is dry, provide bright indirect light, feed during the growing season, and make sure your pot has proper drainage.

Pothos are resilient plants, and with the right adjustments, most recover quickly. Remove any yellow leaves to keep the plant looking its best and to help it focus energy on healthy new growth. With consistent care, your pothos will reward you with long, lush trailing vines for years to come.

Frequently Asked Questions

Why are my pothos leaves turning yellow?

Yellow pothos leaves are most commonly caused by overwatering, underwatering, or too much direct sunlight. Identifying which issue applies to your plant is usually straightforward, and the fix is simple once you know the cause.

How do I fix an overwatered pothos?

Let the soil dry out completely between waterings, ensure your pot has drainage holes, and never let pothos sit in standing water. If root rot has set in, trim away brown or mushy roots and repot into fresh, well-draining soil.

How often should I water my pothos?

Most pothos need watering every 7–10 days, but use the soil as your guide — water thoroughly when the top 1–2 inches of soil feel dry. Always water until it runs freely from the drainage holes to moisten the entire root ball.

Can too much sun cause pothos leaves to turn yellow?

Yes, direct sunlight can cause yellow patches, bleached spots, or scorched brown edges on pothos leaves. Move the plant a few feet from bright windows or filter light with a sheer curtain, as pothos prefer indirect light.

What does an underwatered pothos look like?

An underwatered pothos typically has yellow leaves accompanied by drooping, crispy leaf edges, and dry soil that pulls away from the pot. Despite being drought-tolerant, pothos still need regular watering to stay healthy.
