Why Is My Pothos Leaf Curling? Uncovering the Common Causes
Your pothos is an expert communicator, and leaf curl is its primary signal for distress. Understanding the “why” is the first step to finding the “how” to fix it. These common problems are the most likely culprits, and identifying the right one is easier than you think.
Underwatering: The #1 Culprit
This is, by far, the most common reason for pothos leaf curl. Think of it like this: when your plant is thirsty, it tries to conserve moisture. It does this by curling its leaves inward, reducing the surface area exposed to light and air, which in turn slows down transpiration (the plant equivalent of sweating).
If the leaves feel dry, crispy, and are accompanied by drooping stems and dry, pulling-away soil, underwatering is almost certainly your issue. Don’t worry—this is also the easiest problem to solve!
Overwatering: A Deceptive Twin
It sounds counterintuitive, but overwatering can cause the exact same symptom: curling leaves. How? When the soil is constantly waterlogged, the roots can’t breathe. They become starved of oxygen and begin to rot, a condition known as root rot.
Damaged, rotting roots can’t absorb water and nutrients to send to the leaves, even though there’s plenty of water available. The plant becomes “thirsty” because its delivery system is broken. You’ll often see yellowing leaves along with the curl, and the soil will be soggy to the touch. This issue is more serious but still fixable if caught early.
Low Humidity: A Cry for Moisture
Pothos are tropical plants that thrive in humid environments. If the air in your home is too dry (a common issue in winter when heaters are running), your pothos will lose moisture from its leaves faster than its roots can absorb it. To protect itself, it will curl its leaves.
You might notice the leaf edges turning brown and crispy in addition to the curling. It’s a clear sign your plant is craving a more tropical, spa-like atmosphere.
Pests: Unwanted Houseguests
Sometimes, the problem isn’t environmental but biological. Tiny pests like spider mites, mealybugs, and thrips feed on the sap from your pothos leaves. As they suck out the plant’s juices, they cause damage that leads to curling, yellowing, and stippling (tiny dots) on the leaves.
A close inspection is needed here. Check the undersides of the leaves and the nooks where the leaf meets the stem. You might see fine webbing (spider mites), tiny white cottony masses (mealybugs), or minuscule black specks (thrips).
Light and Temperature Stress
While generally adaptable, pothos have their preferences. Too much direct, harsh sunlight can scorch the leaves, causing them to curl away from the light source to protect themselves. You might also see pale, “bleached” patches on the leaves.
Similarly, sudden temperature changes can stress the plant. A pothos placed too close to a drafty window, an air conditioning vent, or a heating radiator may curl its leaves in protest of the extreme hot or cold air.
Your Step-by-Step Pothos Leaf Curl Guide to Diagnosis
Okay, we know the potential causes. Now it’s time to play detective and pinpoint exactly what your plant needs. Follow this simple pothos leaf curl guide to get your answer. This is a crucial part of learning how to pothos leaf curl can be diagnosed and treated effectively.
-
The Finger Test for Soil Moisture: This is your most reliable tool. Forget watering on a strict schedule and learn to listen to the soil. Stick your index finger about two inches deep into the pot.
- If it comes out bone dry and clean, your plant is underwatered.
- If it comes out wet with dark, muddy soil sticking to it, your plant is likely overwatered.
- If it feels slightly moist and cool, the watering is probably just right.
- Inspect the Leaves Closely: Look at more than just the curl. Are the leaves yellow? This often points to overwatering. Are they crispy and brown at the edges? Think underwatering or low humidity. Do you see tiny spots, sticky residue, or fine webbing? It’s time to look for pests.
- Assess Your Environment: Where is your plant living? Is it sitting in a south-facing window getting blasted by the afternoon sun? That could be a light issue. Is it directly under an AC vent or next to a heater? That points to temperature stress or low humidity.
- Check the Roots (If Necessary): If you strongly suspect overwatering and root rot, you may need to perform a wellness check. Gently slide the plant out of its pot. Healthy roots should be firm and white or light tan. If you see dark, mushy, and smelly roots, you’ve found your culprit: root rot.
How to Fix Pothos Leaf Curl: Targeted Solutions for a Happy Plant
Once you’ve diagnosed the problem, the solution is usually simple. Here are some essential pothos leaf curl tips tailored to each specific issue. Acting on these will turn things around quickly.
Solution for Underwatering: A Deep, Satisfying Drink
If your pothos is thirsty, give it a thorough soak. Take it to the sink or shower and water it until you see water flowing freely from the drainage holes at the bottom of the pot. This ensures the entire root ball is saturated.
For severely dehydrated plants, try bottom watering. Place the pot in a basin with a few inches of water and let it soak up water from the bottom for 30-60 minutes. The leaves should start to uncurl within 24 hours.
Solution for Overwatering: Drying Out and Repotting
Stop watering immediately! Move the plant to a spot with bright, indirect light and good air circulation to help the soil dry out. If you’ve confirmed root rot, you’ll need to intervene.
Gently remove the plant, trim away any black, mushy roots with clean scissors, and repot it in a fresh, well-draining potting mix. Choose a pot with plenty of drainage holes. Then, be much more conservative with your watering going forward.
Boosting Humidity: Simple Tricks for a Tropical Vibe
This is an easy and enjoyable fix! Grouping your pothos with other plants creates a small, humid microclimate. You can also place it on a pebble tray—a shallow tray filled with pebbles and water. As the water evaporates, it will increase the humidity around the plant.
Misting the leaves a few times a week can help, but for a more permanent solution in very dry homes, a small humidifier is a fantastic investment for all your tropical plants.
Evicting Pests: Gentle but Effective Methods
For pests like spider mites and mealybugs, start by wiping the leaves down with a damp cloth to physically remove as many as you can. Then, spray the entire plant (tops and bottoms of leaves) with a solution of insecticidal soap or neem oil.
Neem oil is a wonderful, eco-friendly pothos leaf curl solution. You may need to repeat the treatment weekly for a few weeks to break the pest life cycle. Be sure to isolate the infected plant to prevent the pests from spreading.
The Benefits of Addressing Pothos Leaf Curl Promptly
Fixing a curling leaf isn’t just about aesthetics; it’s about the long-term health and vitality of your plant. Understanding the benefits of pothos leaf curl management will motivate you to stay observant.

Sustainable Pothos Leaf Curl Prevention: Long-Term Care Tips
The best cure is always prevention. Once your plant is healthy again, a few consistent habits can keep it that way. Adopting a sustainable pothos leaf curl prevention strategy is the key to effortless plant care.
Create a Consistent Watering Routine
This doesn’t mean watering every Saturday at 10 AM. It means checking your plant consistently. Get in the habit of doing the finger test every 5-7 days. Water only when the top two inches of soil are dry. This simple habit prevents both over- and underwatering.
Choose the Right Pot and Soil Mix
Good drainage is non-negotiable. Always use a pot with drainage holes. A standard, high-quality indoor potting mix is usually fine, but you can improve drainage by adding a handful of perlite or orchid bark. This creates a light, airy medium that roots love.
Eco-Friendly Pest Management
Make inspecting your plants part of your routine. When you water, take a moment to look over the leaves. Catching a single mealybug is much easier than dealing with a full-blown infestation. A preventative spray of neem oil once a month during the growing season can also be a great, eco-friendly pothos leaf curl deterrent.
The Importance of Regular Check-Ins
Simply spending time with your plants is the best thing you can do. Notice how they look day to day. You’ll quickly learn their patterns and be able to spot the slightest change—like the very beginning of a leaf curl—before it ever becomes a major problem.
Frequently Asked Questions
Here are a few common questions I get from fellow gardeners about their pothos.
Will curled pothos leaves uncurl?
Yes, in most cases! If the curl is due to thirst, humidity, or temperature, the leaves will typically flatten out within a day or two of correcting the issue. Leaves damaged by pests or severe root rot may not fully recover, but the new growth will be healthy.
Should I cut off curled pothos leaves?
Not necessarily. If the leaf is still mostly green, give it a chance to recover after you’ve fixed the underlying problem. If a leaf is yellow, brown, or heavily damaged by pests, it’s best to prune it off with clean shears. This allows the plant to redirect its energy to healthy, new growth.
How can I tell the difference between overwatering and underwatering?
The soil is your best clue! Underwatering = dry, hard, pulling-away soil. Overwatering = wet, soggy, sometimes smelly soil. Additionally, underwatered leaves often feel dry and crispy, while overwatered leaves might feel soft and limp, often accompanied by yellowing.
Your Journey to a Thriving Pothos
See? You’ve got this. A curling leaf on your pothos isn’t a final verdict; it’s the start of a conversation. By learning to listen to its signals—the feel of the soil, the look of the leaves, the conditions of its home—you’ve unlocked the secret to its care.
Remember to be patient with your plant and with yourself. Plant care is a journey, not a destination. Every challenge you overcome, like solving the mystery of a pothos leaf curl, makes you a more intuitive and successful gardener.
Keep observing, keep learning, and enjoy the lush, beautiful greenery that your happy, healthy pothos will bring to your space for years to come. Happy gardening!
