Why Is My Pothos Getting Brown Spots

Your pothos is getting brown spots due to a handful of common care issues that are easy to fix once you know what to look for.
 
If you’ve noticed your pothos getting brown spots, don’t panic — it’s a very common problem among plant parents.
 
The key to stopping those pothos brown spots is figuring out the exact cause so you can adjust your care routine.
 
In this post, we’ll explore the top reasons why is my pothos getting brown spots, how to diagnose the issue, and what steps you can take to restore your plant’s health.
 
Let’s dive right into the most likely culprits behind those unsightly brown spots on your pothos.

Why Is My Pothos Getting Brown Spots? Common Causes

The most common reason why is my pothos getting brown spots comes down to watering habits, but there are other factors too.
 
Here are the main causes that lead to pothos getting brown spots:

1. Overwatering and Root Rot

Overwatering is the number one reason why your pothos is getting brown spots.
 
When soil stays soggy for too long, roots can’t get enough oxygen and begin to rot.
 
As root rot progresses, the leaves develop soft, dark brown spots that often have a yellow halo around them.
 
If you suspect overwatering is causing those pothos brown spots, check the soil moisture before watering again.
 
Stick your finger an inch into the potting mix — if it feels wet, hold off on watering.
 
Let the soil dry out completely between waterings to prevent future pothos getting brown spots from overwatering.

2. Underwatering and Dehydration

On the flip side, underwatering can also result in your pothos getting brown spots.
 
When a pothos doesn’t get enough water, the leaves become dry and crispy, and brown spots appear along the edges or tips.
 
These brown spots from underwatering often look dry and brittle, unlike the mushy spots from overwatering.
 
If you notice your pothos getting brown spots and the soil feels bone dry, it’s time to give it a thorough soak.
 
Water your pothos until water runs out of the drainage hole, then let it drain completely before putting it back in its saucer.
 
Consistent watering — when the top inch of soil feels dry — will help stop those pothos brown spots from underwatering.

3. Low Humidity and Dry Air

Pothos are tropical plants that love humidity, and dry indoor air can cause pothos getting brown spots.
 
When the air is too dry, especially during winter or in air-conditioned rooms, the leaf edges turn brown and crispy.
 
These brown spots usually appear first on the tips and margins of the leaves.
 
If you’re wondering why is my pothos getting brown spots despite proper watering, low humidity could be the answer.
 
Increase humidity by misting your pothos regularly, placing a humidifier nearby, or setting the pot on a pebble tray with water.
 
Grouping your pothos with other plants can also help raise the moisture level around the leaves.

4. Direct Sunlight and Leaf Burn

Too much direct sunlight can scorch pothos leaves, leading to pothos getting brown spots.
 
Pothos prefer bright, indirect light — direct sun rays, especially through a window, can burn the foliage.
 
The brown spots from sunburn are usually dry and bleached-looking, often on the side of the leaf that faces the sun.
 
If you suspect sun is causing your pothos brown spots, move the plant to a spot with filtered light or a few feet from a bright window.
 
Sheer curtains are a great way to protect your pothos while still giving it plenty of light.

5. Fertilizer Burn or Salt Buildup

Another reason why is my pothos getting brown spots could be too much fertilizer.
 
When you feed your pothos too often or use a strong synthetic fertilizer, salts can accumulate in the soil and burn the roots.
 
This root burn shows up as brown spots on the leaves, often beginning at the tips and spreading inward.
 
To fix pothos getting brown spots from fertilizer burn, flush the soil with distilled water to wash out excess salts.
 
Then scale back on fertilizing — once a month during the growing season is plenty for most pothos.

How to Identify the Cause of Pothos Brown Spots

Now that you know the common reasons for pothos getting brown spots, let’s look at how to tell them apart.
 
The appearance and location of the brown spots give you strong clues about the underlying issue.

1. Soft, Dark Brown Spots with Yellow Halos

If your pothos has soft, dark brown spots surrounded by a yellow ring, overwatering and root rot are likely.
 
Check the roots — if they’re mushy and smell bad, trim away the rotted parts and repot in fresh, well-draining soil.

2. Dry, Crispy Brown Tips and Edges

Dry, crispy brown spots on the tips and along leaf edges point to underwatering or low humidity.
 
Feel the soil — if it’s dry an inch down, give your pothos a good drink.
 
If the soil is moist, then increase humidity around the plant.

3. Bleached or Faded Brown Patches

Bleached-looking brown patches on leaves exposed to direct sunlight indicate sunburn.
 
Move your pothos to a shadier spot and the new growth will be healthy and spot-free.

4. Brown Spots Concentrated on Older Leaves

If the pothos brown spots appear mainly on older leaves near the base, it could be a natural aging process or a nutrient imbalance.
 
But if you see spots on new growth too, then it’s more likely one of the issues above.

How to Fix and Prevent Pothos Getting Brown Spots

Once you’ve identified why your pothos is getting brown spots, take action to fix the problem and prevent it from coming back.

1. Adjust Your Watering Routine

For pothos brown spots caused by watering issues, the fix is straightforward.
 
Water only when the top inch of soil feels dry, and make sure your pot has drainage holes.
 
If you’ve been overwatering, let the soil dry out thoroughly before the next watering.
 
If you’ve been underwatering, soak the pot and then water on a more consistent schedule.

2. Increase Humidity Levels

To prevent pothos getting brown spots from dry air, boost humidity around your plant.
 
A humidifier set to 50-60% works wonders, but a pebble tray or regular misting also helps.
 
Keep your pothos away from drafts, heaters, and air conditioning vents that dry out the air.

3. Provide Proper Light

Place your pothos in bright, indirect light to avoid sunburn while still giving it enough energy to thrive.
 
If the only spot you have gets direct sun, use a sheer curtain to filter the light.
 
Rotate the pot every week so all sides get equal exposure and you won’t see one-sided brown spots.

4. Prune Damaged Leaves

Once you’ve fixed the cause, prune off leaves with brown spots to encourage new, healthy growth.
 
Use clean, sharp scissors and cut the leaf stem close to the main vine.
 
Removing damaged leaves also helps the plant focus its energy on recovery.

5. Flush Soil and Adjust Fertilizing

If fertilizer burn is behind your pothos getting brown spots, flush the soil with distilled water three or four times.
 
Then stop fertilizing for a month or two and only use a balanced, diluted liquid fertilizer afterward.

So, Why Is My Pothos Getting Brown Spots?

Your pothos is getting brown spots primarily due to improper watering — either too much or too little — but low humidity, direct sun, and fertilizer issues can also be the cause.
 
The good news is that pothos are resilient plants, and once you correct the underlying problem, your pothos will bounce back with healthy, spot-free leaves.
 
By paying attention to the type and location of the brown spots, you can quickly diagnose why your pothos is getting brown spots and take the right steps to fix it.
 
Keep an eye on your watering schedule, adjust humidity and light, and your pothos will reward you with lush green foliage without those frustrating brown spots.
 
Happy planting, and may your pothos stay spot-free from now on.
