Curling leaves can sometimes be a tricky problem for a plant parent to have because there are quite a few possible causes. In this post, you will find all of the most common reasons why your Satin Pothos has curling leaves. It’s important you go through one by one to find out what is causing it so you can fix the problem as soon as possible.
Issues with watering are the number one cause of plant problems, and curling leaves are no different. Consistent underwatering will mean your Satin Pothos’ leaves will begin to curl as they go into shock and shrivel up. Although Satin Pothos plants don’t like to have really soggy soil, they aren’t drought tolerant.
Make sure you stick to your watering routine, giving your Satin Pothos more during spring and summer and holding off a little during the winter months where your plant is dormant. We recommend quickly checking the moisture levels in the soil before you water your Pothos as you can then start to understand if it needs more or less.
Overwatering and root damage
Much like underwatering, too much water can also make your Satin Pothos curl up. Whilst they aren’t the most water sensitive plant, overwatering can cause a whole range of issues. The main one being root rot.
If your Satin Pothos’ roots begin to rot they won’t be able to take up any water or nutrients from the soil. This starves the plant of vital resources for growth and the leaves may begin to curl. They will also likely turn soft and yellow so watch out for these signs too.
Another cause of curling leaves on a Satin Pothos is over fertilisation. We recommend fertilising using a water-soluble fertiliser at lower than recommended strength every month or so during spring and summer. Hold off giving any fertiliser during the winter months as your Pothos will not be producing any new growth.
If you are fertilising more often, then it may be the cause of the curling leaves. Replace the potting soil and reduce how much you are fertilising. You can even leave it out completely if you want to – it’s sort of an added extra and better to skip it than cause more harm.
The wrong amount of light is also a cause of curling leaves in Satin Pothos plants. Both too much and too little light will make the leaves curl but luckily there is a simple way to find out which it is.
If your Satin Pothos is receiving too much light, the leaves will curl inwards. This is how the plant protects itself against the light. By curling inwards it is reducing the surface area that the sun is hitting.
However, if your Pothos plant is not getting enough light then it will curl upwards in the direction of the light source. This is how the plant tries to increase the amount of sunlight hitting the leaf.
Too much heat
Even if your plant isn’t getting direct sunlight, if the temperature is too hot, your Satin Pothos may start to curl its leaves. Hotspots in rooms caused by sunlight, radiators or cookers can mean that the temperature is a lot hotter in a small spot of the room. It makes it difficult to notice as you may find the overall room temperature to be perfectly fine!
Make sure you move your plant at least 1 metre away from any radiators, heating vents or cookers to prevent overheating.
This is quite a rare cause as Satin Pothos plants don’t often get attacked by pests but an infestation of scale insects, spider mites or mealybugs may be causing the leaves to curl. Get up close to your Satin Pothos’ leaves using a magnifying glass and inspect the tops and undersides of the leaves to see if you can spot any insects.
There are a few ways to get rid of spider mites and other pests, including showering, neem oil and insecticide sprays. You can find out more about identifying, treating and preventing pests in our downloadable ebook.
