I noticed one vine on my pothos curling inward like it was trying to hide from something, while the rest of the plant looked completely fine. My first thought was underwatering, so I watered it. Nothing changed.

Then I blamed the heater running nearby, then the fertilizer I’d used the week before, then I finally checked for pests hiding under the leaves.

Turns out pothos leaves curling can point to almost anything, watering, humidity, temperature, light, fertilizer, even Epipremnum aureum’s response to pests or transplant shock. That ambiguity is exactly what makes it so frustrating to diagnose.

This post walks you through a quick way to figure out which cause is actually yours, so you’re not guessing your way through six fixes before finding the right one.

Quick Answer: Figure Out Which Cause Is Yours First

Before diving into every possible cause, run through this quick check. Start with the soil: is it bone-dry or soggy? That points straight to a watering issue. If the soil feels fine, think about your environment: has it been dry, drafty, or unusually hot or cold lately?

Next, consider your care routine: did you fertilize or repot recently? Finally, flip a few leaves over and check for pests. Working through these in order usually narrows things down fast, without reading through every section hoping one clicks.

Watering Issues: The Most Common Cause

Watering is the single most common reason behind pothos leaves curling, and it cuts both ways. Dry, crumbly soil means the plant is curling inward to conserve moisture. Soggy, foul-smelling soil means the roots are suffocating and struggling to function at all.

The fix depends entirely on which one you’re dealing with, so if this sounds like your plant, our full overwatered vs underwatered pothos guide breaks down every leaf and soil clue side by side. And if the soil’s been wet for a while with no improvement after drying out, check the roots directly using our pothos root rot guide.

Low Humidity

Pothos is a tropical vine at heart, and tropical roots mean it prefers moderate to high humidity, generally somewhere above 40 percent. When indoor air turns dry, especially during winter with the heater running or in summer with the AC blasting, leaves curl inward to reduce the surface area exposed to that dry air and slow down water loss.

This is one of the more overlooked causes, since the soil often looks perfectly fine while the air around the plant is the actual problem.

A few fixes work well here: misting the leaves a few times a week, setting the pot on a pebble tray filled with water, running a humidifier nearby, or simply grouping several plants together, since they create a small pocket of shared humidity around each other.

Temperature Stress

Pothos likes a fairly narrow comfort zone, generally between 60 and 85°F. Step outside that range in either direction, and curling shows up as one of the first warning signs. Cold drafts from a nearby window, an air conditioning vent, or a door that opens to the outside can trigger sudden curling, especially if the plant sits close to the source.

Sudden swings matter as much as the extremes themselves, a plant moved from a warm room to a cold porch, even briefly, can react within hours. On the heat side, intense afternoon sun through a window or proximity to a heater has a similar effect.

The fix is mostly about placement: keep your pothos away from drafts, vents, and radiators, and aim for a spot with steady, moderate conditions year-round.

Too Much or Too Little Light

Light-related curling tends to show a directional clue that other causes don’t. Too much direct sun, particularly intense afternoon light, can scorch leaf edges and cause them to curl downward and away from the light source as a protective response.

Too little light works differently, leaves may curl or reach awkwardly toward whatever light source is available, along with slower, leggier growth overall. If you’re using a grow light, being too close or running it too many hours a day can cause similar stress to direct sun.

The fix is simple relocation: move a sun-stressed pothos a few feet back from the window, or move a light-starved one somewhere brighter, ideally bright indirect light rather than direct rays.

Overfertilization

More fertilizer doesn’t mean more growth, it usually means more problems. Applying too much, or feeding more often than the plant needs, leads to salt buildup in the soil, which pulls moisture away from the roots instead of helping them absorb it.

Curling from overfertilization often shows up alongside brown, crispy tips, since the root damage affects the whole leaf’s ability to stay hydrated. Pothos generally only needs light feeding every two to three months during the growing season, and even then, diluting fertilizer to half strength helps avoid this problem entirely.

If you suspect a buildup has already happened, flush the soil by running water through the pot for a few minutes, letting it drain fully, and holding off on fertilizing again for a few months.

Pests

Sap-sucking insects like spider mites, mealybugs, and aphids can cause curling by draining moisture and nutrients directly from leaf tissue, leaving it deformed and stressed. These pests are easy to miss at first since they tend to cluster on the undersides of leaves and along stems rather than out in the open.

A close inspection, ideally with good light and maybe a magnifying glass for spider mites specifically, will usually reveal small moving specks, sticky residue, or tiny webbing. Once confirmed, neem oil or insecticidal soap applied directly to the affected areas works well for most infestations, and a homemade solution of diluted rubbing alcohol and dish soap is a solid backup option.

Regular inspection catches these early, before an infestation spreads across the whole plant.

Transplant Shock and Pot-Bound Roots

If your pothos started curling shortly after a repot, transplant shock is a likely explanation. Moving roots into new soil disrupts their environment temporarily, and curling is a common, usually short-lived stress response while the plant adjusts. This typically resolves within a few days to a couple of weeks with normal care.

A slower, more chronic version of this comes from the opposite problem: roots that have outgrown their pot entirely. Pot-bound roots have nowhere left to expand, which restricts water and nutrient uptake even with a normal watering routine.

If it’s been over a year or two since the last repot and growth has slowed noticeably, checking the roots for tight circling patterns is worth doing.

How to Fix Curling Pothos Leaves

Once you’ve identified your cause, here’s the fix at a glance.

Dry soil: water thoroughly and check again in a few days. Soggy soil: let it dry out and inspect the roots.

Dry air: mist, use a pebble tray, or run a humidifier.

Temperature extremes: relocate away from drafts, vents, or direct heat sources. Too much or too little light: move a few feet closer to or farther from your light source.

Fertilizer buildup: flush the soil and dilute future feedings.

Pests: inspect leaf undersides and treat with neem oil or insecticidal soap.

Recent repot: give it time, most transplant shock resolves on its own within a couple of weeks.

Preventing Future Leaf Curl

Most of these causes come back to consistency. Check soil moisture by feel before watering rather than sticking to a fixed calendar, and keep your pothos somewhere with stable temperature and humidity, away from vents, drafts, and radiators.

Fertilize lightly and infrequently, diluted and only during the active growing season, rather than reaching for it out of habit. Make pest checks part of your routine care, a quick glance under the leaves every time you water costs nothing and catches problems early.

Finally, keep an eye on pot size as your pothos grows, repotting every year or two into something just slightly larger keeps roots from ever becoming the problem.

Can curled leaves go back to normal?

It depends on the cause and how early you catch it. Curling from dehydration, low humidity, or minor temperature stress often reverses once conditions improve. But leaves damaged by fertilizer burn, pest feeding, or sunburn usually stay curled permanently, even after you fix the underlying issue. New growth should come in normal once the cause is resolved.

What does an overwatered pothos look like?

Overwatered pothos leaves turn soft, limp, and yellow rather than crispy, often with curling on top of that. The soil stays soggy and heavy, sometimes with a foul odor, and stems can feel mushy near the base. If this sounds familiar, check the roots, it may already be root rot.

Is it better to let pothos hang or climb?

Both are fine for the plant’s health, it really comes down to look and space. Climbing on a moss pole or trellis encourages larger, more mature leaves over time, since pothos naturally grows upward on trees in the wild. Hanging is easier to manage and gives that classic trailing vine look. Neither affects susceptibility to curling.

How long does it take for pothos to recover from transplant shock?

Most pothos bounce back within a few days to about two weeks after repotting. Curling, drooping, or minor leaf loss during this window is normal. Keep care consistent, stable light, moderate watering, no fertilizer, and avoid the temptation to move it around while it adjusts.

Can sugar water help with transplant shock?

Not really, and it’s worth skipping. Plants produce their own sugars through photosynthesis rather than absorbing them through the roots, so sugar water doesn’t feed the plant the way it sounds like it should. It can actually encourage bacterial or fungal growth in already-stressed soil. Stable conditions and patience do more than any additive here.

Do pothos like big pots or small pots?

Slightly snug is better than oversized. A pot that’s too large holds much more soil and moisture than the roots can use, which keeps the soil wet longer and raises the risk of root rot. When repotting, size up gradually, going just one to two inches larger in diameter rather than jumping to something much bigger.

Curling Is a Message, Not a Death Sentence

Curling leaves feel alarming, but they’re really just your pothos asking for a small adjustment. Once you identify the cause, most fixes are simple and quick.

If watering turned out to be the culprit, my overwatered vs underwatered pothos and root rot guides walk through the rest.

Key Takeaways

• Curling isn’t one thing, it can point to almost any care issue. Watering, humidity, temperature, light, fertilizer, pests, or transplant shock can all trigger it.
• Start with soil, then work outward. Check moisture first, then environment (humidity, temperature, light), then recent care changes, then pests.
• Watering is the most common cause, but it’s covered in depth elsewhere. Dry soil means underwatered, soggy soil means overwatered or possibly root rot.
• Low humidity is an easy one to miss. Soil can look fine while dry indoor air is the actual problem, especially in winter or with AC running.
• Light-related curling has a directional clue. Curling away from a light source often means too much sun. Reaching toward it often means too little.
• Fertilizer burn shows up alongside brown, crispy tips. Flushing the soil and diluting future feedings usually resolves it.
• Pests hide on leaf undersides. Regular inspection catches spider mites, mealybugs, and aphids before they spread.
• Not all curling reverses. Dehydration and minor stress often uncurl, but fertilizer burn, pest damage, and sunburn usually stay, new growth should come in normal once the cause is fixed.
