Crossandra, also known as the firecracker flower, is a popular indoor and outdoor plant that is native to India. The plant produces beautiful bright orange or yellow flowers that bloom throughout the year. However, one common issue that many crossandra plant owners face is curling leaves. This article will explore the reasons why crossandra plant leaves curl and how to fix the problem.
Lack of Water
One of the most common reasons why crossandra plant leaves curl is a lack of water. Crossandra plants require consistent watering to grow and thrive. If the soil around the plant is dry, the leaves will start to curl to protect themselves from losing too much water.
To fix this issue, water your crossandra plant regularly. You should water it deeply once every week or whenever the top inch of soil feels dry. Make sure not to overwater your plant as this can lead to root rot which can also cause curling leaves.
Humidity
Crossandra plants require high humidity levels to grow properly. If the air around your plant is too dry, it can cause the leaves to curl and become crispy. This is because the lack of moisture in the air makes it difficult for the plant to absorb enough water through its leaves.
To fix this issue, you can increase the humidity levels around your crossandra plant by misting it regularly or placing a humidifier nearby.
Pests
Pests such as spider mites and thrips can also cause crossandra plant leaves to curl. These pests suck the sap from the leaves, causing them to become distorted and curled. You may also notice small webs or discoloration on the leaves if spider mites are present.
To fix this issue, you can use an insecticidal soap or neem oil spray on your plant to get rid of these pests. You can also prune off any heavily infested leaves.
Disease
Diseases such as powdery mildew and leaf spot can also cause curling leaves in crossandra plants. Powdery mildew appears as a white powdery substance on the leaves, while leaf spot appears as dark spots with yellow halos.
To fix this issue, you can use a fungicide spray to treat your plant. Make sure to remove any infected leaves and dispose of them properly to prevent the disease from spreading.
Nutrient Deficiency
A nutrient deficiency can also cause curling leaves in crossandra plants. If your plant is not getting enough nutrients such as nitrogen, potassium or magnesium, the leaves will start to curl and become yellow or brown.
To fix this issue, you can fertilize your plant with a balanced fertilizer. Make sure to follow the instructions on the fertilizer package and do not over-fertilize your plant.
Environmental Stress
Environmental stress such as extreme temperatures or exposure to direct sunlight can also cause curling leaves in crossandra plants. If the plant is exposed to too much heat or cold, it will start to curl its leaves to protect itself from damage.
To fix this issue, you should move your crossandra plant to a location with more suitable temperature and lighting conditions. You should also avoid placing your plant in direct sunlight as this can cause leaf burn and curling.

In conclusion, curling leaves in crossandra plants can be caused by a variety of factors such as lack of water, humidity, pests, disease, nutrient deficiency and environmental stress.
