If the foliage is crispy and curled then it will not turn green again. But if the foliage is still soft and green. There are bright chances of recovery after watering the plant.

Take your plant to the sink and fill the sink with water. Gently place your plant in it and let the soil absorb water through the bottom holes.

It will take a maximum of 5 minutes to absorb sufficient water. Then take it out of the sink and let it drain extra water.

Overwatering

Overwatering is a rare case of curled leaves of Chinese evergreen plants. It results in the yellowing of leaves. If you do not fix it on time then plant roots will get damaged.

For beginners, it is hard to know whether underwatering or overwatering is the cause. Because both conditions have similar symptoms.

To prevent overwatering, you should only water your plant once the top few inches of the soil become dry. Also, use the well-draining soil so that in case of accidental overwatering the potting soil drain the extra water and save your plant.

Do not follow any watering schedule because watering applications depend upon many factors like the temperature of the room, humidity, and light.

Light

Chinese evergreen plant needs low light to grow and to produce healthy colorful leaves. Leaf curling occurs when you expose your plants to direct sunlight.

The high intense light waves increase the temperature of the plant. This increases the water usage and the soil becomes dry. Your plant starts using the water that is stored in its leaves.

When the leaves go out of the water this turns their edges and if you do not notice this problem on time. The leaves will turn crispy brown and curled.

To prevent leaf curling because of high bright light. You need to move your plant to a less bright place. A sunny window will be the best option. 

Burned and brown leaves will not recover. Therefore, it is best to cut them off the plant. This way you can save a huge amount of plant energy.

Air Moisture

In low humidity, Chinese Evergreen plant leaves start curling. Because they consume some amount of moisture from the sir.

When the room air gets dry the plant becomes unable to absorb moisture.

This increases dehydration and results in curled Chinese evergreen leaves.

Tips to improve room humidity:

In winters do not place your plant near the heating vents.

Chinese evergreen plant does not need a plant humidifier. Just spray some water on its leaves and place it away from direct sunlight in a cool room

Grouping the plants together will also improve the room humidity by 7%

If you have only one plant then use a pebble tray, place your plant pot over it. Just make sure the waterline cannot touch the bottom part of the pot.

Over Use of Fertilizers

Chinese evergreens do not need a high dose of fertilizers. They are happy if the soil has a good amount of organic material like compost.

But when you use an excessive amount of fertilizers then this will surely damage your plants. Synthetic fertilizer is made up of chemicals.

They build up around the roots and block their natural function. This results in dehydrated and nutrient-deficient plants.

When a plant does not get proper nutrition, it becomes unable to make a sufficient amount of plant food. This weak the plant and leaves start curling themselves due to weakness.

To prevent overfertilization you must need to read the instruction of the bottle before use. Use fresh clean water to dilute the desired amount of fertilizer. Then pour it into the base of the plant.

You can also use the soil flushing method to clean the soil once in 90 days. This will reduce the chances of overfertilized burn to 95%. 

Temperature Stress

Chinese evergreens are tropical plants which means they love to grow in warm weather. The ideal temperature range is 65 to 85 degrees F.

When the temperature goes above 85 F this increases the water loss and results in dehydration.

A temperature is lower than 65 degrees F damages the plant internal tissues. This results in dark spots, black stems, and curled leaves.

The defense mechanism of the plant folds its leaf tips to save it from cold drafts.

Try to maintain the room temperature constant, little bit fluctuations are not a problem. To keep eye on the room temperature you can use grow room temperature monitor.

Unhealthy water

If you use unhealthy water for watering Chinese evergreen. This will curl their leaves because such water contains many unwanted minerals.

A heavy amount of copper, chlorine, and fluoride in the water sits at the base of the plant. Too much of them block the nutrient supply to the plant roots.

To prevent this problem, you should use healthy water. Pure water that you use for drinking is safe for watering Chinese evergreen plants. 

Do not use tap water because it contains some amount of chlorine in it.

Diseases

Leaf curling, wilting and yellowing of leaves are common symptoms of disease attack.
