Pothos leaves curl inward due to common care issues like improper watering, low humidity, or pest infestations.
If you’ve noticed your pothos leaves curling inward, it’s a sign the plant is stressed.
Understanding why pothos leaves curl inward helps you fix the problem quickly.
In this post, we’ll explore the main reasons pothos leaves curl inward and how to treat each cause.
Let’s dive into why your pothos leaves are curling inward and what you can do about it.
Why Are My Pothos Leaves Curling Inward?
Pothos leaves curl inward as a response to environmental stress or improper care.
Here are the most common reasons your pothos leaves curl inward:
1. Underwatering Causes Pothos Leaves to Curl Inward
The most frequent reason pothos leaves curl inward is lack of water.
When the soil dries out completely, the plant’s cells lose turgor pressure.
Pothos leaves curl inward to conserve moisture, making them look wilted or cupped.
Check the soil: if it feels bone dry an inch down, underwatering is the culprit.
Give your pothos a thorough soak and watch the leaves uncurl within a day or two.
2. Overwatering Also Makes Pothos Leaves Curl Inward
Surprisingly, too much water can also cause pothos leaves to curl inward.
Overwatering leads to root rot, which damages the roots’ ability to take up water.
Even though the soil is wet, the plant gets dehydrated, and pothos leaves curl inward as a result.
If the soil feels soggy and leaves are curling, let it dry out before watering again.
Repotting with fresh, well-draining soil may be necessary if root rot has set in.
3. Low Humidity Triggers Pothos Leaves to Curl Inward
Pothos are tropical plants that thrive in moderate to high humidity.
When indoor air is dry, especially in winter or air-conditioned rooms, pothos leaves curl inward to reduce water loss.
The leaf edges may also turn brown or crispy alongside the curling.
Increasing humidity with a pebble tray, humidifier, or occasional misting can help stop pothos leaves from curling inward.
4. Too Much Direct Light Causes Pothos Leaves to Curl Inward
Pothos prefer bright, indirect light but scorch in direct sun.
If your pothos leaves curl inward and have faded or burnt spots, light stress is likely.
Direct sunlight forces the plant to close its stomata, and pothos leaves curl inward as a protective mechanism.
Move your pothos to a spot with filtered light, like near an east-facing window, to prevent further curling.
5. Pest Infestations Lead to Pothos Leaves Curling Inward
Pests like spider mites, aphids, or thrips suck sap from the leaves.
As they feed, the leaf cells become damaged, and pothos leaves curl inward or distort.
Look for webbing, tiny insects, or sticky residue on the undersides of leaves.
Treat infestations with insecticidal soap or neem oil to stop your pothos leaves from curling inward further.
6. Temperature Stress Makes Pothos Leaves Curl Inward
Pothos are sensitive to drafts, cold windows, or sudden temperature changes.
If your pothos leaves curl inward and the plant is near an air vent or drafty door, temperature stress is the cause.
Keep your pothos in a stable environment between 65–85°F (18–29°C) to avoid curling.
Cold shock especially makes pothos leaves curl inward or become limp.
How to Fix Pothos Leaves Curling Inward
Once you identify why your pothos leaves curl inward, you can take corrective steps.
Here’s how to fix curling pothos leaves based on the cause:
1. Adjust Watering for Curling Pothos Leaves
Check the soil moisture with your finger before watering.
Water only when the top inch of soil feels dry to prevent both underwatering and overwatering.
Use a pot with drainage holes so excess water can escape.
Consistent watering will stop pothos leaves from curling inward due to moisture stress.
2. Boost Humidity Around Your Pothos
Place a humidifier near your pothos or set the pot on a pebble tray filled with water.
Grouping plants together can also raise local humidity.
Misting pothos leaves occasionally helps, but don’t rely on it alone.
Higher humidity will help pothos leaves uncurl and stay flat.
3. Relocate Your Pothos to Better Light
Move your pothos to a spot with bright, indirect light, like a few feet from a window.
Avoid south-facing windows that get harsh afternoon sun.
If leaves are already curled, they should recover within a week after moving.
Proper light prevents pothos leaves from curling inward from sun stress.
4. Treat Pests Promptly
Isolate the affected plant and wipe leaves with a damp cloth to remove pests.
Apply neem oil or insecticidal soap weekly until the infestation is gone.
Healthy pothos leaves will stop curling inward once pests are eliminated.
5. Stabilize Temperature and Drafts
Move your pothos away from heating vents, air conditioners, and drafty windows.
Avoid placing it near exterior doors that open frequently.
Maintaining a steady room temperature will prevent pothos leaves from curling inward due to shock.
Preventing Pothos Leaves from Curling Inward
Prevention is easier than fixing curled leaves.
Follow these tips to keep your pothos healthy and avoid pothos leaves curling inward:
1. Water on a Schedule
Create a consistent watering routine based on your home’s conditions.
Use a moisture meter if you’re unsure about soil dryness.
Avoid letting the soil dry out completely or stay waterlogged.
A regular schedule minimizes stress that leads to pothos leaves curling inward.
2. Monitor Humidity Levels
Keep humidity above 40% for best growth.
Use a hygrometer to track humidity in your home.
During dry months, run a humidifier near your pothos.
Adequate humidity will prevent pothos leaves from curling inward.
3. Provide Consistent Light
Place your pothos in a location where it gets steady, indirect light year-round.
Rotate the pot occasionally so all sides receive even light.
Avoid moving it from low light to bright light suddenly.
Steady light prevents stress that causes pothos leaves to curl inward.
4. Inspect Regularly for Pests
Check the undersides of leaves weekly for signs of bugs.
Quarantine new plants for a few weeks before adding them to your collection.
Early detection stops pests from causing pothos leaves to curl inward.
5. Maintain Stable Temperatures
Keep your pothos away from cold windows in winter and hot windows in summer.
Avoid placing it near heat sources or air conditioning outlets.
A stable environment keeps pothos leaves from curling inward.
So, Why Are My Pothos Leaves Curling Inward?
Pothos leaves curl inward due to factors like improper watering, low humidity, too much direct light, pests, or temperature stress.
By checking these common issues, you can identify the cause and take action.
Fixing the underlying problem usually resolves pothos leaves curling inward within a few days.
With proper care, your pothos will have flat, healthy leaves again.
Remember to water appropriately, boost humidity, provide indirect light, and inspect for pests regularly.
Understanding why pothos leaves curl inward helps you keep your plant thriving.
Happy growing, and enjoy your beautiful, uncurled pothos.
