White licorice plants are a beautiful addition to any garden with their striking foliage and unique fragrance. However, like any other plant, they are vulnerable to fungal infections. Fungal infections can cause discoloration, wilting, and even death of the plant. Fortunately, there are several ways to get rid of fungus on white licorice plants.
Before you can treat fungus on your white licorice plant, you need to identify the type of fungus that is affecting it. Common fungal infections that affect white licorice plants include powdery mildew, black spot, and rust.
Powdery Mildew
Powdery mildew appears as a white or gray powdery substance on the leaves, stems, and flowers of the plant. The affected areas may also turn yellow or brown and eventually fall off.
Black Spot
Black spot appears as circular black spots on the leaves of the plant. The affected leaves may turn yellow and fall off.
Rust
Rust appears as orange, yellow, or brown spots on the leaves of the plant. The affected leaves may also have a powdery texture.
Once you have identified the type of fungus affecting your white licorice plant, you can choose a treatment option to get rid of it.
Prune Affected Areas
If the fungus has only affected a small part of the plant, pruning the affected areas may be enough to get rid of it. Use clean pruning shears to cut off any infected leaves or stems. Be sure to dispose of them properly to prevent further spread of the fungus.
Neem Oil
Neem oil is a natural fungicide that can be used to treat powdery mildew, black spot, and rust. Mix one tablespoon of neem oil with one gallon of water and spray the solution on the affected areas of the plant. Repeat this process every seven to ten days until the fungus is gone.
Fungicide
If the other treatment options have not worked, you may need to use a fungicide. Look for a fungicide that is labeled for use on white licorice plants and follow the instructions carefully. Be sure to wear gloves and protective clothing when using a fungicide.
