Pothos leaves turn yellow for several common reasons, and the good news is most are easy to fix.
If you’ve been noticing your pothos plant’s leaves turning yellow, you’re not alone because this is one of the most frequent issues plant owners face.
The main culprits behind pothos leaves turning yellow include overwatering, underwatering, improper light, nutrient problems, or even pests.
In this post, we’ll break down why your pothos leaves are turning yellow and how you can get your plant back to its lush green self.
Let’s dive into what’s causing those yellow leaves on your pothos.
Why Are My Pothos Leaves Turning Yellow?
There isn’t just one reason behind pothos leaves turning yellow, but the most common trigger is watering issues.
Let’s look at each cause so you can diagnose your plant quickly.
1. Overwatering Is the Top Cause of Pothos Leaves Turning Yellow
When you give your pothos too much water, the roots sit in soggy soil and can’t breathe properly.
This leads to root rot, which directly causes pothos leaves turning yellow because the damaged roots can’t deliver nutrients.
If the yellow leaves are also soft and mushy, overwatering is likely the issue behind your pothos leaves turning yellow.
Let the soil dry out completely between waterings to prevent this from happening again.
2. Underwatering Can Also Cause Pothos Leaves to Turn Yellow
On the flip side, pothos leaves turning yellow can happen when the plant doesn’t get enough water either.
When a pothos is thirsty, older leaves often turn yellow and dry out as the plant conserves moisture.
If your pothos leaves are turning yellow and feel crispy or brittle, underwatering is the probable cause.
Check the soil with your finger; if it’s bone dry an inch deep, it’s time to give your pothos a good drink.
3. Lighting Problems Lead to Pothos Leaves Turning Yellow
Pothos plants need bright, indirect light to stay healthy, and pothos leaves turning yellow can signal too much or too little light.
Direct sunlight scorches the leaves, causing yellow or brown patches, while very low light makes leaves pale and yellow over time.
Move your pothos to a spot with medium to bright indirect light for best results.
If you notice pothos leaves turning yellow only on the side facing the window, rotate the plant regularly.
4. Nutrient Deficiencies Cause Pothos Leaves to Turn Yellow
When a pothos runs low on essential nutrients like nitrogen or iron, leaves start yellowing from the bottom up.
This is another common reason for pothos leaves turning yellow, especially if you haven’t fertilized in months.
Feed your pothos with a balanced liquid fertilizer during the growing season (spring and summer) to keep pothos leaves from turning yellow.
Be careful not to overfertilize, which can burn roots and also cause pothos leaves turning yellow.
How to Fix Yellow Leaves on Pothos Plants
Once you know why your pothos leaves are turning yellow, you can take action to reverse the damage.
Follow these steps to help your pothos recover.
1. Adjust Your Watering Routine
For overwatered pothos, stop watering until the soil is completely dry, then water only when the top inch feels dry.
For underwatered pothos, give a thorough soak until water drains from the bottom, and stick to a regular schedule.
Consistent moisture is key to preventing pothos leaves turning yellow from watering stress.
2. Move Your Pothos to the Right Light
Find a spot with bright, indirect light, such as near an east or north-facing window.
Avoid direct sun, which burns leaves, and avoid dark corners, which cause pothos leaves turning yellow from lack of light.
If you can’t provide natural light, a grow light works great to keep pothos leaves from turning yellow.
3. Trim Yellow Leaves and Check for Pests
Once a pothos leaf turns yellow, it won’t turn green again, so snip it off with clean scissors.
This redirects energy to healthy growth and prevents disease from spreading.
Inspect your pothos for pests like spider mites or mealybugs, which suck sap and cause pothos leaves turning yellow.
Wipe leaves with neem oil or insecticidal soap if you see any bugs.
Preventing Pothos Leaves from Turning Yellow Going Forward
The best cure for pothos leaves turning yellow is good prevention through consistent care.
Here are habits that keep your pothos vibrant and green.
1. Water Only When Needed
Stick your finger into the soil once a week; water only when the top 1–2 inches feel dry.
Pothos prefer to dry out slightly between waterings, which stops pothos leaves turning yellow from overwatering.
2. Provide Steady, Indirect Light
Keep your pothos in a spot where it gets plenty of bright but filtered sunlight all year.
If leaves start looking pale or pothos leaves are turning yellow, adjust the location immediately.
3. Fertilize Lightly During Growing Season
Feed your pothos once a month with a diluted houseplant fertilizer in spring and summer.
Skip fertilizing in fall and winter because the plant rests and too much can cause pothos leaves turning yellow.
4. Repot Every Year or Two
Rootbound pothos can’t absorb nutrients well, leading to pothos leaves turning yellow.
Repot into a slightly larger pot with fresh soil to give roots room and refresh nutrients.
So, Why Are My Pothos Leaves Turning Yellow?
Pothos leaves turn yellow due to a handful of fixable causes: overwatering, underwatering, poor lighting, nutrient issues, or pests.
If you’ve been asking why your pothos leaves are turning yellow, start by checking your watering habits and light conditions.
With a few simple adjustments, you can stop pothos leaves turning yellow and enjoy a thriving, green plant again.
Remember that even healthy pothos occasionally drop old leaves, but if you see widespread yellowing, take action quickly.
Now you know exactly why pothos leaves turn yellow and how to fix it.
