How do you treat coleus fungi?
You can use either homemade or store-bought fungicides to treat fungus-infected coleus plants. If the leaves are infected, dip a cotton cloth in fungicide and wipe the infected leaves. Alternatively, you can spray the fungicide directly onto the leaves if the infection is very severe. However, if the soil of your coleus plant is infected, it is recommended to repot the plant in a fresh soil mixture in a new pot.
