What should the leaves of your pothos look like? This houseplant should have glossy, healthy, sturdy and almost straight heart shaped leaves.
Yes, they do tend to curl a bit at the very tip, and they have a slight curve, but how about when they are curling? The answer is that your pothos is not healthy.
If your pothos looks droopy or the leaves are curling, chances are your plant is underwatering. Sometimes the pothos gets so dry that when you water it, the water flows through it. If this appears to be the case, let your plant sit in the water for a few hours to get as much water from bottom to top as needed.
So, if your beloved trailing houseplant has curling leaves, just read on and you will find out both the causes and possible treatments for your ailing pothos.
Six Reasons Why Pothos Leaves Curl
If the leaves of your pothos are curling, there it may be due to one of the flowing six causes. Not all are as serious, though; some are more worrying than others
Pothos Leaves Curling: Should You Worry?
If the leaves of your pothos, or Epipremnum aureum as botanists call it, curl, the first thing you need to do is assess which one is the reason for this. Once you have done that, you can choose the right treatment for the specific reason.
So, the first thing we need to do is to look at the six reasons in turn and in detail…
Pothos Leaves Curling: Is It Underwatering?
As we said, underwatering may well be the main reason why your pothos is curling its leaves. When water is scarce, the plant loses turgor, which means that the cells become flaccid, as it is the water that keeps them turgid.
This becomes more apparent in leaves and flowers, which do not have a rigid structure as strong as stems.
But What Can You Do About It?
The answer to underwatering is watering it appropriately and regularly, it is not overwatering!
Pothos Leaves Curling: Is the Temperature Wrong?
When the leaves of your pothos curl, another common reason may be that there’s something wrong with the temperature.
Whether it is too hot, too cold or your houseplant has suffered from sudden changes of temperature, it may want to show you this by curling its leaves. Pothos has a very limited temperature range it can bear, so, be careful.
What Can You Do About It?
As a rule of thumb, always keep an eye on your pothos when the weather and season change; it is very likely to suffer from it, and curling leaves will be the first symptom.
Have You Fertilized It Too Much?
If you give your pothos too much fertilizer, it will have excessive nutrients, and this imbalance can cause the leaves of your houseplant to curl. Pothos do not like to feed too much, in fact they like little fertilization but regularly.
You should never fertilize your pothos more than twice a month.
What should you do if you realize that you have given your plant too much fertilizer? There are two cases:
In The First Case The Solution Is Simple:
In Case There Are Other Signs, And The Plant Is Suffering Severely, You Will Need Some Drastic Action:
After you have done this, wait before you fertilize it again; there may still be excessive nutrients attached to the roots.
Pothos Leaves Curling: Is the Light Wrong?
Pothos is very sensitive to light exposure as a houseplant. In a way, it will tolerate moderate light, but it will not stand direct light indoors. If outdoors, partly shaded areas are best indicated.
The fact is that pothos is a plant coming from a specific island, called Mo’orea in French Polynesia, which is covered in rich forests that shade it from direct sunlight. The leaves can easily burn if exposed to direct light, especially indoors.
On the other hand, just because of its resilience to dimly lit places, people tend to put it in corners or on top of shelves and cupboards where the light is actually too low.So, the first thing you need to find out is whether the light is too much or too little. You can do it using common sense, but if you want a test, check how the leaves behave:
The solution is simple: Move your pothos where there is more or less light accordingly.
In any case, never expose your pothos to direct light indoors. Plenty is fine, but only if diffuse and indirect.
Pothos Leaves Curling: Is It Root Rot?
Root rot can cause the leaves of your pothos to curl as well.
However, this ailment also causes many other symptoms, including rotting at the base of the stem, the leaves will also yellow, with an unhealthy shade of this color; then its leaves eventually turn dark brown and rot.
Root rot is a very, very serious problem: the life of your pothos is at risk!
So, take this seriously and try to act as fast as possible.

Keep an eye on your pothos after you have repotted it; this is a major treatment, and you will need to make sure it is recovering well.
Pothos Leaves Curling: Is It an Infestation?
Sometimes, insects and pests cause plants to lose energy and this makes them curl their leaves. It happens with pothos too.
Especially pests that suck the sap out of your plant can cause it to weaken, and the first signs will be leaves that droop or curl.
The best way to go about this is to prevent it; of course, a balanced ecosystem is the ideal answer, but this is very hard to obtain indoors. But there are other ways of preventing this from happening:
If it is too late for prevention, keep it in mind for after the treatment. However, there are very easy home remedies like neem oil or even soap water, or, if you prefer, garlic water, to get rid of pests, depending on the species.
Garlic water is a strong repellant, and it will work with most pests; don’t worry, your pothos will not stink of garlic for long.
We Humans can only smell it for 24 hours after applying it, and then only animals, who have a much better sense of smell, will be able to.
It is so effective that it is the only pest control system used for the amazing rose garden of in Buckingham Palace.
If you want to make it even stronger, just add a chili pepper with the garlic.
If you have pests that need to stick to the plant, it is easy to get rid of them by using soap water. This makes it impossible for them to hold on to the plant.
Repeat after a week or two if necessary.
With some very strong pests, however, like mites, you may need to use a natural insecticide. The most common one is neem oil.
That’s it. This, I will remind you, is not necessary with most pests, only very hard ones, and, in any case, it is also a repellant, so, you can do it to prevent infestations, which is always better.
Pothos Leaves: Are They Perking Up?
Pothos is a very sensitive plant in many respects. Funny because people only look at it as a low maintenance plant, which is true.
The point is that it requires very little care as long as some conditions (feeding, watering, light and temperature) are right.
Once you get these right, your pothos will be no hassle at all. Still, remember to check on its leaves regularly, because if they curl, something is not right…
Whether it is too much feeding, underwatering, wrong light or temperature, an infestation or even root rot, if it curls its leave it’s because it is asking you for help.
