Firesticks plant, also known as Euphorbia tirucalli, is a succulent plant that is native to Africa. It is a popular plant among gardeners and interior designers due to its striking red, orange, and yellow colors. However, one common problem that firesticks plant owners face is fungus growth. Fungus can cause the leaves and stems of the plant to turn brown or black, and if not treated promptly, it can lead to the death of the plant.

In this article, we will discuss how to get rid of fungus on firesticks plants and prevent it from recurring.

Identify the Type of Fungus

Before you start treating your firesticks plant for fungus, it is essential to identify the type of fungus affecting your plant. There are several types of fungi that can grow on firesticks plants, including powdery mildew, black spot, and rust.

Powdery mildew appears as a white or grayish powder on the leaves and stems of the plant. Black spot causes black spots on the leaves, while rust leads to reddish-brown spots on the leaves.

Identifying the type of fungus helps you choose the right treatment method for your plant.

Remove Infected Leaves and Stems

Once you have identified the type of fungus affecting your firesticks plant, the next step is to remove all infected leaves and stems. Use a sharp pair of scissors or pruning shears to cut off all infected parts of the plant.

Be sure to dispose of the infected leaves and stems in a sealed bag to prevent the spread of spores to other plants.

Apply Fungicide

After removing all infected parts of the plant, apply fungicide to prevent further growth of fungus. You can purchase fungicide from your local gardening store or make your own using a mixture of baking soda and water.

Spray the fungicide on the remaining parts of the plant, making sure to cover all surfaces thoroughly. Repeat this process every two weeks until the fungus is completely gone.

Improve Air Circulation

Fungus thrives in damp environments, so it is essential to improve air circulation around your firesticks plant. You can do this by placing a fan near the plant, opening windows, or moving the plant to a location with better airflow.

Improving air circulation helps to reduce humidity levels around the plant, making it less hospitable for fungus growth.

Avoid Overwatering

Overwatering is one of the most common causes of fungus growth on firesticks plants. It is essential to water your plant only when the soil is dry to the touch.

Avoid watering the leaves and stems directly as this can create a damp environment that promotes fungal growth.


Fungus growth on firesticks plants can be a frustrating problem for plant owners. However, with proper identification and treatment, you can get rid of fungus and prevent it from recurring.

Remember to remove infected leaves and stems, apply fungicide, improve air circulation, and avoid overwatering your plant. With these steps, your firesticks plant will remain healthy and vibrant for years to come.
