Echinacea, also known as cone flower, is a popular herbaceous perennial plant that belongs to the daisy family. It is widely used for its medicinal properties and is commonly grown in gardens. However, one of the most common problems faced by gardeners is curling leaves on Echinacea plants. This article will explore the possible causes of this problem and how to treat it.


Overwatering is a common cause of curling leaves in Echinacea plants. When the soil is too wet, it can lead to root damage and poor absorption of nutrients. As a result, the plant may develop curled leaves as a sign of stress. To avoid overwatering, make sure the soil is well-draining and only water when the top inch of soil is dry.


On the other hand, underwatering can also cause Echinacea leaves to curl. When the plant is not receiving enough water, it may curl its leaves as a way of conserving moisture. To prevent this, make sure to water your Echinacea plant regularly and deeply.

Pests and Diseases

Pests and diseases can also cause leaves to curl on Echinacea plants. Common pests that attack these plants include aphids, spider mites, and thrips. These pests suck the sap from the leaves, causing them to curl and turn yellow. Diseases such as powdery mildew and leaf spot can also cause curled leaves. To prevent pest and disease problems, make sure to keep your garden clean and free from debris.

Environmental Factors

Environmental factors such as high temperatures or low humidity can also cause Echinacea plant leaves to curl. When exposed to high temperatures, the plant may lose moisture quickly, leading to curled leaves. Low humidity can also cause moisture loss through transpiration, leading to curled leaves. To prevent this, make sure to provide your Echinacea plant with enough shade and water during hot and dry weather.

Nutrient Deficiencies

Nutrient deficiencies can also cause curled leaves on Echinacea plants. Lack of essential nutrients such as nitrogen, magnesium, and iron can lead to stunted growth and curled leaves. To prevent this, make sure to fertilize your plants regularly with a balanced fertilizer.

How to Treat Curling Leaves on Echinacea Plants

The treatment of curled leaves on Echinacea plants depends on the underlying cause. If the problem is due to overwatering or underwatering, adjust your watering schedule accordingly. If pests or diseases are the cause, use an appropriate pesticide or fungicide to control the problem. If environmental factors are the cause, provide shade and water as needed. Finally, if nutrient deficiencies are the cause, fertilize your plants regularly.
