What Causes Pothos Leaves To Turn Yellow

Pothos leaves turn yellow primarily because of watering issues, lighting problems, or nutrient deficiencies.
 
If you’ve noticed your pothos leaves turning yellow, you’re not alone and it’s a common concern for plant lovers.
 
The good news is that once you understand what causes pothos leaves to turn yellow, you can usually fix the problem fast.
 
In this post, we’ll dive into the main reasons behind pothos leaves turning yellow and how you can bring your plant back to health.
 
Let’s get started.
 

Why Pothos Leaves Turn Yellow

Pothos leaves turn yellow for several distinct reasons, and each one requires a slightly different approach.
 
Here are the most common causes of pothos leaves turning yellow:
 

1. Overwatering Is the Top Cause of Yellow Pothos Leaves

Overwatering is the number one reason pothos leaves turn yellow.
 
When the soil stays soggy, roots can’t breathe and they begin to rot.
 
Root rot prevents the plant from absorbing nutrients, which makes older pothos leaves turn yellow first.
 
If you see yellow leaves with dark, mushy stems, overwatering is likely the culprit behind your pothos leaves turning yellow.
 

2. Underwatering Can Also Make Pothos Leaves Turn Yellow

Ironically, pothos leaves turn yellow from underwatering too.
 
When the plant goes too dry, leaves start to wilt and then yellow from the bottom up.
 
Underwatered pothos leaves turn yellow, become crispy, and often curl at the edges.
 
Letting the soil dry out completely for too long stresses the plant and triggers yellowing.
 

3. Poor Lighting Contributes to Pothos Leaves Turning Yellow

Lighting plays a huge role in whether pothos leaves turn yellow.
 
Too much direct sun can scorch leaves, causing them to yellow and brown.
 
Too little light slows photosynthesis, and the plant responds by dropping or yellowing its lower leaves.
 
Finding the right balance helps prevent pothos leaves turning yellow from light stress.
 

4. Nutrient Deficiencies Cause Pothos Leaves to Yellow

If your plant isn’t getting enough fertilizer, pothos leaves turn yellow over time.
 
Nitrogen deficiency is especially common – it makes older pothos leaves turn yellow while new growth stays green.
 
Iron or magnesium shortages can also cause pothos leaves to yellow between the veins.
 
Feeding your pothos regularly keeps those pothos leaves from turning yellow due to hunger.
 

5. Pests and Diseases Trigger Yellow Pothos Leaves

Spider mites, mealybugs, and scale insects suck sap from leaves, causing pothos leaves to turn yellow.
 
Fungal infections from overwatering can also make pothos leaves turn yellow and drop off.
 
Inspect the undersides of leaves if you see pothos leaves turning yellow unexpectedly.
 

How to Fix Yellow Leaves on Pothos

Once you know why your pothos leaves are turning yellow, you can take action to reverse the damage.
 
Here’s how to fix pothos leaves turning yellow from each cause:
 

1. Adjust Your Watering Routine

For overwatered pothos, let the soil dry out completely before watering again.
 
If root rot has set in, trim away rotten roots and repot in fresh, dry soil.
 
For underwatered pothos, give it a thorough soak and water when the top inch of soil feels dry.
 
Consistent watering keeps pothos leaves from turning yellow due to moisture stress.
 

2. Move Your Plant to Better Light

Place your pothos in bright, indirect light – near an east- or north-facing window works great.
 
If you have pothos leaves turning yellow from too much sun, move it a few feet back from the window.
 
For low-light areas, consider adding a grow light to stop pothos leaves from turning yellow.
 

3. Fertilize Sparingly but Regularly

Use a balanced, water-soluble fertilizer every 4-6 weeks during the growing season.
 
Dilute it to half strength to avoid burning the roots, which can also make pothos leaves turn yellow.
 
Yellow pothos leaves from nutrient deficiency will green up once you start feeding.
 

4. Treat Pests Immediately

Wipe leaves with neem oil or insecticidal soap to remove pests causing pothos leaves to turn yellow.
 
Isolate the plant until the infestation is gone so it doesn’t spread.
 
Healthy pothos leaves rarely turn yellow from pests once treated early.
 

Preventing Yellow Leaves on Pothos

The best way to deal with pothos leaves turning yellow is to prevent it from happening in the first place.
 
Follow these simple care tips to keep your pothos leaves green and vibrant:
 

1. Water Only When the Soil Is Dry

Stick your finger an inch into the soil – if it’s dry, it’s time to water.
 
Use a pot with drainage holes so excess water never sits around the roots.
 
This single habit stops most pothos leaves from turning yellow.
 

2. Provide Consistent Bright Indirect Light

Rotate your pothos every few weeks so all leaves get even light exposure.
 
Avoid placing it in drafty spots or near heating vents, as temperature swings can make pothos leaves turn yellow.
 

3. Repot Every Year or Two

Fresh soil replenishes nutrients and gives roots room to grow.
 
A root-bound pothos often shows signs like pothos leaves turning yellow from stress.
 
Repotting in spring keeps your plant happy and reduces yellowing.
 

So, What Causes Pothos Leaves to Turn Yellow?

Pothos leaves turn yellow primarily because of watering issues, lighting problems, or nutrient deficiencies.
 
Overwatering is the most frequent reason pothos leaves turn yellow, followed closely by underwatering and poor light.
 
Pests and lack of fertilizer can also make pothos leaves turn yellow if left unchecked.
 
The key is to observe your plant closely and adjust care as soon as you notice pothos leaves turning yellow.
 
With a little attention, you can fix yellow pothos leaves and enjoy a lush, green plant for years.
 
Happy planting.
