Updated: June 14, 2022

Firesticks plant, also known as Euphorbia tirucalli, is a succulent plant that is popular for its bright red or orange color. However, like all plants, it is prone to mold growth, especially in humid environments. Mold can be detrimental to the health of the plant and can cause it to wilt or die. In this article, we will discuss how to get rid of mold on firesticks plant.

Identify the Mold

Before you can get rid of mold on your firesticks plant, you need to identify the type of mold that is growing on it. There are many types of mold that can grow on plants, including powdery mildew, black spot, and botrytis. Each type of mold requires a different treatment method, so it’s important to identify the mold correctly.

One way to identify the mold is by its appearance. Powdery mildew looks like white or gray powder on the leaves and stems, while black spot appears as black spots on the leaves. Botrytis looks like grayish-brown fuzzy patches on the leaves and stems.

Remove Affected Leaves

Once you have identified the mold, the next step is to remove the affected leaves. If the mold is limited to just a few leaves, you can simply cut them off using a pair of scissors or pruning shears. Be sure to sterilize your cutting tool with rubbing alcohol before and after each use to prevent spreading the mold.

If the mold has spread extensively throughout the plant, you may need to consider trimming back the entire plant. This will allow you to remove all affected areas and give your firesticks plant a fresh start.

Apply Fungicide

After removing the affected leaves or trimming back the plant, it’s important to apply a fungicide to prevent further mold growth. A fungicide is a chemical or biological agent that kills or inhibits the growth of fungi.

There are many types of fungicides available, including systemic and contact fungicides. Systemic fungicides are absorbed by the plant and protect it from the inside out, while contact fungicides only protect the surface of the plant.

When choosing a fungicide, be sure to read the label carefully and follow the instructions for application. Some fungicides may require dilution before use, while others may need to be applied directly to the affected areas.

Improve Air Circulation

One of the main reasons why mold grows on plants is due to poor air circulation. When there is not enough air movement around the plant, moisture can accumulate on the leaves and stems, creating a breeding ground for mold.

To improve air circulation around your firesticks plant, you can place a fan near it or move it to an area with better ventilation. You can also space out your plants to give them more room to breathe.

Reduce Humidity

Mold thrives in humid environments, so it’s important to reduce humidity levels around your firesticks plant. You can do this by running a dehumidifier in the room or using a humidity meter to monitor the levels.

Another way to reduce humidity is by watering your plants less frequently. Overwatering can lead to excess moisture in the soil, which can contribute to mold growth. Be sure to only water your firesticks plant when the top inch of soil feels dry to the touch.
