A curled pothos leaf is a clue, not a diagnosis. The trick is figuring out what else changed around the same time.
Before changing your plant's routine, check three things: the soil, the location, and the rest of the foliage. Those clues can usually point you toward the most likely source of stress.
1. Your pothos is too dry
Start with the simplest possibility: check the potting mix. Pothos should be allowed to dry somewhat between waterings, but leaving the plant dry for too long can cause visible stress.
Penn State notes that too little water can cause pothos leaves to temporarily droop. If curling appears alongside limp foliage and noticeably dry soil, moisture is worth investigating.
Look for...
- Dry potting mix
- A pot that feels unusually light
- Leaves that feel limp as well as curled
- Soil pulling away from the sides of the pot
- A plant that perks up after a thorough watering
What to do
If the soil is genuinely dry, water thoroughly and allow excess water to drain from the container.
Don't compensate by keeping the soil constantly wet afterward. Pothos prefers a well-drained growing medium and should be allowed to dry somewhat before being watered again.
2. The roots are staying too wet
This is why curled leaves shouldn't automatically trigger another watering.
Pothos can develop root rot when kept too wet. Damaged roots may struggle to support healthy foliage even though plenty of moisture is sitting in the pot.
Investigate the roots if...
- The soil stays wet for a long time
- The pot has poor or nonexistent drainage
- The plant looks stressed even though the soil is moist
- Leaves are also yellowing
- Roots are brown, black, soft, or deteriorating
If the potting mix is still wet, don't add more water simply because the leaves are curling. Let the condition of the soil and roots guide your next step.
Dry soil and wet soil can both accompany an unhappy-looking pothos. Always touch the potting mix before deciding that curled leaves mean “water me.”
3. The light is too intense
Pothos does well in moderate to bright indirect or filtered light, but it does not need harsh direct sun.
If curling appeared after moving the plant closer to a bright window or into stronger sunlight, look for other signs of light stress such as yellowing, bleaching, or damaged areas.
Moving the plant back into bright, indirect light may provide a better environment without sending it to the opposite extreme of a very dark corner.
4. Temperature or drafts have changed
Location matters for more than light. Pothos is a tropical plant, and Wisconsin Extension specifically recommends keeping it away from drafts.
Think about what is happening around the plant. Has it recently been moved beside an air-conditioning vent, heater, frequently opened exterior door, or drafty window?
Sudden environmental changes can stress houseplants even when your watering routine hasn't changed.
5. The plant may be root-bound
Curling alone doesn't prove that a pothos needs a larger pot, but an overcrowded root system can make moisture management increasingly difficult.
A pot-bound plant may dry unusually quickly because there is relatively little potting mix left to hold moisture.
Check for a crowded root system if...
- Roots are growing through the drainage holes
- The potting mix dries much faster than it used to
- Growth has slowed despite otherwise appropriate care
- Roots are densely circling the root ball
Don't repot based on curled leaves alone. Look for several signs that the plant has actually outgrown its container.
6. Check carefully for pests
Pothos generally has relatively few pest problems, but it can still be affected by common houseplant pests.
Mealybugs and scale are among the more common pests found on pothos, and spider mites can occasionally appear as well.
Inspect the undersides of leaves, stems, leaf joints, and new growth. Look for cottony material, unusual bumps, sticky residue, fine webbing, speckling, or visible insects.
7. New leaves may simply still be unfurling
Before diagnosing a problem, make sure the “curled” leaf isn't simply a new leaf that hasn't finished opening.
New pothos growth emerges folded and gradually expands. A young leaf that is still opening is different from an established leaf that suddenly begins curling after previously lying flat.
Look at the rest of the plant. Healthy new growth with otherwise normal foliage is much less concerning than curling that begins appearing across multiple mature leaves.
Start Here
What do your curled leaves look like?
Start by checking whether the plant has simply become too dry.
Don't water again yet. Investigate excess moisture and root health.
Compare the new light, temperature, and airflow with the plant's previous location.
Inspect leaves and stems closely for insects, webbing, bumps, or sticky residue.
Check whether the root system has become crowded inside the container.
Give it time to unfurl before assuming something is wrong.
Should you cut off curled pothos leaves?
Not automatically.
A curled leaf may still be healthy and useful to the plant, particularly if the problem is temporary or the leaf is simply still unfurling.
Consider removing foliage if it is badly damaged, dying, or affected by a problem that makes removal appropriate. Otherwise, correcting the underlying growing conditions is more important than making the plant look perfect immediately.
Will curled pothos leaves flatten again?
It depends on why they curled and how much damage has occurred. Leaves affected by temporary water stress may improve after the underlying problem is corrected, while physically damaged or severely stressed foliage may never look completely normal again.
Watch the plant's new growth. Healthy new leaves are often a better sign of recovery than waiting for every older leaf to become cosmetically perfect.
When should you worry?
One unusual leaf isn't necessarily an emergency. Pay closer attention when curling is spreading across the plant or appears alongside yellowing, wilting, root deterioration, pest activity, or stalled growth.
That's when it's worth investigating the plant as a whole rather than treating the curled leaf by itself.
