Why Are My Pothos Leaves Getting Brown Spots

Pothos leaves get brown spots due to several common issues, most of which are easy to fix.
 
If you’ve noticed your pothos leaves are getting brown spots, you’re likely dealing with watering problems, humidity levels, or even sun exposure.
 
The good news is that brown spots on pothos leaves don’t usually mean the plant is dying, they’re just a signal that something in its care routine needs adjusting.
 
In this post, we’ll break down why your pothos leaves are getting brown spots, how to identify the cause, and what you can do to stop new brown spots from forming.
 

Why Do Pothos Leaves Get Brown Spots?

Pothos leaves get brown spots for a handful of reasons, and the first step is figuring out which one applies to your plant.
 
Here are the most common culprits behind brown spots on pothos:
 

1. Overwatering or Underwatering

The number one reason pothos leaves get brown spots is inconsistent watering.
 
When you overwater, the roots suffocate in soggy soil, which leads to root rot.
 
Root rot then stops the plant from taking up nutrients, and the leaves respond with brown spots, often along the edges or tips.
 
On the flip side, underwatering also causes pothos leaves to develop brown spots because the plant dries out and cells die.
 
Both overwatering and underwatering produce pothos leaves with brown spots, so check the soil moisture before you assume the cause.
 

2. Low Humidity

Pothos naturally love a bit of humidity, so when the air in your home is too dry, pothos leaves get brown spots.
 
The brown spots from low humidity usually show up as crispy, dry patches, especially on the leaf tips.
 
If your pothos leaves are getting brown spots and the rest of the plant looks fine, low humidity is a strong suspect.
 
Grouping plants together or using a small humidifier can help reduce those brown spots on pothos leaves.
 

3. Too Much Direct Sunlight

Pothos thrive in bright, indirect light, but direct sun can scorch their leaves.
 
Sunburn causes pothos leaves to get brown spots that look bleached or papery in the middle of the leaf.
 
If your pothos is sitting in a south- or west-facing window, the intense rays might be why your pothos leaves have brown spots.
 
Move it a few feet back from the window, and the brown spots on pothos will stop appearing on new growth.
 

Other Causes of Brown Spots on Pothos Leaves

Beyond watering and light, a few other factors can make pothos leaves turn spotty.
 
Let’s look at less obvious reasons why your pothos leaves are getting brown spots:
 

1. Fertilizer Burn

Too much fertilizer, or using it too often, can cause salt buildup in the soil.
 
This salt burn shows up as brown spots on pothos leaves, usually at the tips and edges.
 
If you’ve been feeding your pothos regularly and notice brown spots forming, cut back on fertilizer for a month.
 
Flush the soil with water to wash away excess salts, and your pothos leaves will stop getting that type of brown spot.
 

2. Tap Water Chemicals

Pothos are sensitive to chemicals like chlorine and fluoride found in many tap water supplies.
 
These chemicals can cause pothos leaves to get brown spots, especially on the tips.
 
Switch to filtered water, rainwater, or let tap water sit out overnight before watering.
 
Making this small change often stops new brown spots on pothos from appearing.
 

3. Bacterial or Fungal Infections

Sometimes pothos leaves get brown spots from a bacterial leaf spot disease or a fungal infection.
 
These brown spots usually have a yellow halo around them and may spread quickly.
 
If you see brown spots on pothos that are soft, wet, or spreading, isolate the plant immediately.
 
Remove affected leaves with clean scissors and improve airflow around your pothos to prevent future brown spots.
 

How to Prevent Pothos Leaves from Getting Brown Spots

Now that you know why pothos leaves get brown spots, here’s how to keep them healthy and spot-free:
 

1. Water Only When the Soil Is Dry

Stick your finger about an inch into the soil.
 
If it feels dry, it’s time to water; if it’s still damp, wait a few more days.
 
This simple habit prevents both overwatering and underwatering, two big reasons pothos leaves get brown spots.
 

2. Provide Consistent Humidity

Mist your pothos occasionally or place it near other plants to create a humid microclimate.
 
A pebble tray with water under the pot also helps keep the air moist.
 
When humidity is steady, pothos leaves stop getting those crispy brown spots.
 

3. Choose the Right Light

Keep your pothos in bright, indirect light, like near an east-facing window or a few feet from a south-facing one.
 
Avoid direct sunlight, which burns leaves and causes brown spots on pothos.
 
With the right light, your pothos leaves will stay green and vibrant.
 

4. Fertilize Sparingly

Feed your pothos only during the growing season (spring and summer), and dilute the fertilizer to half strength.
 
This prevents salt buildup and the resulting brown spots on pothos leaves.
 

5. Use Clean Water

If tap water is causing pothos leaves to get brown spots, switch to filtered or distilled water.
 
Your plant will thank you with healthier leaves.
 

So, Why Are My Pothos Leaves Getting Brown Spots?

Pothos leaves get brown spots for several common reasons, and most are easy to fix.
 
Whether it’s watering issues, low humidity, too much sun, fertilizer burn, or tap water chemicals, you now know how to identify the cause.
 
By adjusting your care routine, you can stop new brown spots on pothos from forming and help your plant recover.
 
Remember, a few brown spots on older leaves are normal, but if your pothos leaves are getting brown spots on new growth, check the conditions listed above.
 
With a little attention, your pothos will bounce back and stay lush and green.
