Leaves curling is the most common problem you may face when caring for dracaena.
If suddenly leaves of your dracaena curling then it is worth taking immediate measures so as not to lose the plant.
To do this, from the beginning you have to identify the causes of this problem.
And only then you can correct the care mistakes and other factors that are responsible for this problem.
Why Are My Dracaena Leaves Curling? Probably the result of too dry air. Sprinkle dracaena leaves and place trays under the plants with water that will gradually evaporate. Also, remember that the dracaena should not stand directly by the radiator. There are other causes of dracaena that leave curling such as excessive light, heat, improper watering, accumulation of salt in the soil, overdose of fertilizer, lack of nutrients, insect infestation, diseases, and temperature fluctuation.
Now, let’s dig deep into the details.
Dracaena leaves Curl Because of Dry Air
The edges of the leaves curl and sometimes become dry. Twisting the leaves of plants is a measure of self-defense because this reduces the surface of the leaf and less water evaporates from it.
This happens when the plant is in a too warm place or receives little water.
In this case, you have to water the plant until the soil is completely saturated, or dip it in water and hold it. Choose a cooler place for your dracaena.
Dracaena Leaves Curl Because of Excessive Light
Another cause of dracaena leaves to curl is too much light. If your dracaena is placed in the windowsill and it gets too much exposure to direct sunlight then the leaves may curl.
Excessive light means higher temperatures. Photosynthesis and other physiological activities will stop when the temperature rises.
So if the temperature increases then the plant uses all its water to cool down its tissues by evaporating. As a result, the leaves curl due to lack of water.
Dracaena leaves Curl Because of Heat
Too high air temperature negatively impacts the physiological process of dracaena. If your indoor temperature is high in winter due to the radiator, your dracaena leaves may show curling symptoms.
Heat and dry air make the plant evaporate more water. Because in this way it cools down itself as a defense mechanism. As a result, the leaves of dracaena curl.
Dracaena leaves Curl Because of Overwatering
You must water regularly to keep your dracaena healthy. But you should carry out watering frequency depending on the season. Also, stagnant water in plant pots is a dangerous thing for the plant.
Excessive watering and stagnant water will cause root rot of your dracaena. Then the root will not be able to absorb enough nutrients from the soil. This will make the plant unhappy and result in curl leaves. Make sure you have a working drainage system.
Dracaena leaves Curl Because of Too Little Water
Another reason for curling dracaena plant leaves is lack of water. If you do not water your plant enough, the plant will show symptoms like curling leaves or drying out.
You need to let the soil dry up between watering. Check the soil moisture from time to time. The topsoil layer of 2-3 cm thick can remain in a dry state until subsequent watering, but then you should water the soil.
The Accumulation of Salt In Soil May Cause Leaf Curling
Normal tap water contains different mineral salt which accumulates within the potting soil. You may know that salt makes the nutrients unavailable for the plants.
So, the plants do not get enough nitrogen and phosphorus to flourish its green leaves. Ultimately the leaves start to show symptoms like curling.
To avoid this try to use filtered or settled water. Keep the normal tap water for 24 hours then it is ready to use. Because within this time the salt minerals will be deposited at the bottom.
Dracaena leaves Curling Due to Overdose of Fertilizer
Excessive feeding will also lead to the loss of the normal state of the leaves. The plant shows the symptoms by curling the leaves.
An overdose of fertilizers is considered to be detrimental to the plant. They can burn the roots and the dracaena will not be able to supply nutrients to other parts.
Dracaena leaves Curling Due to Lack of Nutrients
Nutrients are necessary to grow your dracaena well. Nitrogen plays a vital role in thriving rich green leaves. Also, nitrogen is necessary especially for the formation of green leaves. Lack of nitrogen causes the curling of dracaena leaves.
To restore the curling leaves, it is necessary to fertilize with liquid fertilizer with high nitrogen content. It is convenient to use water-soluble fertilizer for dracaena.
Feed your dracaena with fertilizer once a month during spring and summer. You can also split the dose into twice a month.

Dracaena leaves Curling Due to Insects
Pests do not infect dracaena often, sometimes you may find scale insects, thrips, mealybugs, aphids, and spider mites to infest the plant.
Let’s jump into the details of how you can identify the insects and get rid of them.
These are very tiny insects 2-4 mm in size, covered with a grayish or yellow shield with a wax coating. They suck the juice from the stems and leaves, which turn pale, curl, and dry.
You can get rid of this insect with an alcohol solution or soapy water. Soak a sponge or clean cloth with soap water then wipe the infected parts with it.
I found neem oil to work great against scale insects. Also, you can use insecticides available in the market.
Handle the insecticides with care. Read the instruction and safety measures before applying.
Very small (1-2 mm) insect forming colonies on the lower side of the leaf plate. They suck the juices of the leaves. High temperature and dry air is a favorable condition for this insect.
You can get rid of thrips simply by pruning your dracaena. Prune the infested part of the plant to control the attack of thrips on your plant.
You can also opt for a mild insecticide like neem oil or soap water. These work really great and organic ways of controlling insects.
A small reddish-brown insect is no larger than 0.5 mm in size. You find the affected parts entangled in a barely noticeable cobweb. This is a clear indication that your dracaena is infested by spider mites.
Eventually, you will find chlorosis of leaves and also brown or yellow spots. The growth of the plant is stunted, more susceptible to disease.
In addition, mites themselves are carriers of a number of diseases. You can treat your dracaena infected with spider mite treated with hot (about 50°C/122°F) soapy water, then sprayed with acaricide. Like before, neem oil is a great option for this kind of soft-skinned insect.
The most common type of dracaena pest. These insects love plant juice. Gather on a leaf and suck the juices.
So, the growth of the plant stops and leaves curl. Finding them on the leaves is pretty easy. These insects are white, they also leave a powdery white coating on dracaena.
You can get rid of this kind of mealybug manually. Again, soap solution still becomes one of the main necessary insecticides to fight soft-skinned mealybug. Spray soap water to infested dracaena leaves. Repeat the procedure every 14 days.
You can reduce insect attack significantly maintaining a certain air humidity value in the room.
Diseases are the common cause of curling
Various bacteria, fungi, and parasites become the causes of Dracaena diseases. Among them, Fusarium Leaf Spot and root rot is the most common disease you will find occurring to your plant.
If you do everything correctly and create the optimum conditions for dracaena your dracaena will be happy and healthy.
