Syngonium Leaves Curl (9 causes and solutions) – ISPUZZLE

Syngonium leaves in indoor pot with curling symptoms

Syngonium is very attractive, which is why most people keep it as a houseplant. However, if you want to get the most out of your Syngonium, you need to take good care of it.

If you’re wondering why the leaves of your syngonium are curling, you’ve come to the right place. Curled leaves are a common problem that affects most houseplants, including Syngonium.

The main cause of Syngonium leaf curl is low humidity, improper watering, too much light, lack of nutrients, temperature extremes, or over-fertilization. It is essential to identify the problem by carefully examining the plant and then taking appropriate action to correct the problem.

Reasons Your Syngonium Leaves Are Curling

There are many reasons why Syngonium leaves may curl. Read on to find out the possible reasons why your Syngonium leaves are curling. (Source: University of California)

lack of nutrients

Like other plants, Syngonium needs nutrients to grow and thrive. If your Syngonium does not receive enough nutrients, the leaves will curl.

The color that the leaves acquire depends on the nutrients the plant lacks.

For example, if the plant lacks magnesium, the leaves will slowly curl and turn yellow-green.

On the other hand, if it lacks potassium, the leaves will show signs of necrosis and the leaves will curl up.


If your Syngonium’s leaf curl is caused by a nutrient deficiency, it’s important to do a thorough test to find out which nutrient the plant is deficient in.

For example, if the plant lacks magnesium, it must be supplied with this nutrient.

Provide the plant with a nutrient that your plant lacks. Research shows that Syngonium needs a minimum of 16 ingredients to thrive.

If any of these ingredients are missing, the leaves can be rolled up.

If the potting mix is ​​very old, supplement the soil with these nutrients or fertilizers to promote healthy growth of your Syngonium.

extreme temperature

Extreme temperatures can also cause Syngonium leaves to curl. It can be very hot or extremely cold.

For example, very cold weather during the winter season can cause Syngonium leaves to curl.

Research has shown that Syngonium leaves curl when the temperature drops below 21 degrees Celsius.

Additionally, during the summer when temperatures are extremely high, Syngonium leaves may curl due to excessive transpiration (water loss).


The best solution to protect our Syngonium leaves from curling due to heat stress is to keep your plant indoors to protect it from extremely cold temperatures.

Also, during the summer months when the temperature is too high, be sure to protect your Syngonium from direct sunlight. Syngoniums do not perform well in extreme temperatures.

So be sure to store your Syngonium at the recommended temperature, which is between 7°C and 30°C.

lack of light

Light is crucial for the healthy growth of Syngonium. If your Syngonium does not get enough light, the leaves will slowly curl.

Like any other plant, Syngoniums need light for the process of photosynthesis, which is essential for the health and well-being of the plant.

If the plant cannot make its own food, it will become weak and its leaves will slowly curl up and eventually die.

Insufficient light exposure will also prevent Syngonium leaves from performing their best and over time the leaves will begin to lose their dark color and begin to curl if left untreated, eventually yellow and fall off.


The solution to this is to make sure that you expose your Syngonium to enough light. Syngonium needs at least six hours of light exposure each day to grow healthy.

So be sure to place your Syngonium in a place where it can get enough light, preferably near the window.

Small container size

If you’ve done your best to get your Syngonium to grow healthily, but you find that the leaves are still curling, the problem may be with the size of the container.

Syngonium needs a lot of space to thrive. If the container you stored it in is small, the leaves may curl up.

Syngonium has taproots that go straight into the ground. If your container size is small, you are limiting the plant’s root’s ability to access the essential nutrients it needs to thrive.


The solution to this problem is to ensure that your Syngonium is kept in a large container so that the roots have enough room to receive the essential nutrients the plant needs to grow healthily.


Over-fertilizing gives your Syngonium too much fertilizer. Too much of anything is toxic, as is too much fertilizer on your Syngonium.

However, too much fertilizer can do more harm to your Syngonium than good..

Applying too much fertilizer to your Syngonium can cause chemicals to build up in the soil that can alter water uptake in the Syngonium, causing the leaves to curl and turn yellow.


The best way to avoid this is to make sure you apply the right amount or portion of fertilizer.

Experts recommend fertilizing your Syngonium once or twice a year in spring or summer.

Make sure your fertilizer is high in phosphate, potassium nitrogen, as these are the main nutrients your Syngonium needs to thrive.

If you have just planted your Syngonium in a pot, it is advisable not to add fertilizer to the pot until the root of the plant is well anchored in the ground.

low humidity

Low humidity is a great enemy of Syngonium. Syngonium needs lots of humidity to thrive.

If the plant is not exposed to high humidity (at least 40%), the leaves will curl up and eventually turn yellow.

This is because low humidity increases the rate of transpiration (loss of water through the leaves), which causes leaf curl.

Remember that the leaves are curved to help reduce water loss. A high moisture content helps reduce transpiration and thus prevents the leaves from shifting.


If your home has low humidity, the solution is to increase the humidity to around 30% to reduce the sweat rate.

There are many ways to increase the moisture content of your Syngonium. The most recommended techniques are:

⦿ Use a rock trap method where you fill a shallow dish with rocks and water, then place it over your vigorous plant. The water in the gravel tray will evaporate, increasing the humidity around the plant.

⦿ Another quick but effective way to increase the humidity around the plant is to use a humidifier.

⦿ A humidifier helps increase the humidity in your home. This technique is strongly recommended during the winter season.

⦿ Another way is to place bowls, cups or other containers around the Syngonium to expose the air to the water. The water in the container or pot evaporates, causing an increase in humidity around the Syngonium.

⦿ You can also bring your plant to a room with sufficient humidity

leaf spot disease

Leaf spot disease is a fungal disease that causes brown spots on the leaf. If the disease is not treated in time, it can lead to leaf curling, yellowing and eventually leaf drop.


The best way to treat leaf spot disease is to cut off the infected leaves. You can also use a fungicide if the disease is in its early stages.

Water quality

The quality of water you use in your Syngonium will also determine whether it will thrive or coil.

If you use fluoridated and chlorinated tap water, the water will damage the plant and cause curls.

Tap water also contains other minerals and salt that can be harmful to your plant, causing leaf curl if the concentration is high.

A high concentration of salt in the salt prevents your Syngonium from absorbing water properly, causing the leaves to turn brown and curl.


The solution to this problem is not to use tap water which contains a high concentration of salt and other chemicals such as fluoride and chlorine.

Filtering the water before watering your Syngonium can also help control the type and amount of salt your Syngonium receives, improving the rate of water absorption.

Insufficient watering (too much and too little water)

Too much water and too little water have a negative effect on your Syngonium.

Overwatering gives your Syngonium more water than it needs. If you don’t water your Syngonium plant enough, your Syngonium plant will go into survival mode by shading the leaves to prevent water loss through transpiration.

Before the leaves fall, they curl up and turn yellow. Curling is a technique Syngonium uses to save water when it is scarce.

Overwatering can also cause leaf drop. Syngoniums do not like wet feet, and keeping the soil constantly waterlogged can harm the plant and cause leaf curl.


You need to give your Syngonium enough water. This means you should water above or below your plant.

Experts recommend watering your Syngonium at least once a week to prevent the plant from losing water.

The condition of the floor is also very important. The ground should be moist, not wet.
