Exacum plants, also known as Persian violets or German violets, are popular houseplants that produce delicate, colorful flowers. However, some Exacum plant owners may encounter an issue where the leaves of their plant begin to curl. This can be a concerning problem for many gardeners, but it is usually an indication that something is not right with the plant’s environment. In this article, we will explore some of the common causes of Exacum plant leaf curl and how to remedy them.
Environmental Factors
The most common reason for Exacum plant leaf curl is related to environmental factors. These include:
Overwatering
One of the most significant reasons why Exacum plant leaves curl is overwatering. When the soil is consistently wet or damp, it can cause the roots to rot and prevent them from taking up water and nutrients properly. This can lead to stress on the plant, resulting in curled leaves. To avoid overwatering, make sure that you allow the topsoil to dry out before watering again.
Underwatering
On the other hand, underwatering can also cause Exacum plant leaves to curl. When a plant does not receive enough water, it will try to conserve moisture by curling its leaves. To prevent underwatering, make sure that you water your Exacum plant regularly and adequately.
Temperature Fluctuations
Exacum plants are sensitive to temperature changes, particularly cold drafts or sudden temperature drops. This can cause stress on the plant and result in curled leaves. Make sure that you keep your Exacum plant in a location with stable temperatures between 60 and 75 degrees Fahrenheit.
Humidity
Exacum plants thrive in high humidity environments. If your home or office has low humidity levels, it can cause stress on the plant and result in curled leaves. To increase humidity levels, consider using a humidifier or placing a tray of water near the plant.

Another reason for Exacum plant leaf curl is pests and diseases. These include:
Spider Mites
Spider mites are tiny pests that can cause Exacum plant leaves to curl, discolor, and become brittle. They are commonly found in dry environments and tend to thrive in warm temperatures. To get rid of spider mites, use insecticidal soap or neem oil.
Fungal Diseases
Fungal diseases, such as powdery mildew or leaf spot, can also cause Exacum plant leaves to curl. These diseases are usually caused by poor air circulation, high humidity levels, and overwatering. To prevent fungal diseases, make sure that you provide adequate airflow around the plant and avoid overwatering.
