Short Answer
First, you should identify the type of fungus, as different fungi require different treatments.
If possible, isolate the affected leaf or leaves, and dispose of them in a sealed plastic bag.
Next, use a fungicide to treat the remaining leaves, following the directions on the product label.
Finally, make sure the plant is receiving enough airflow and that the soil is draining properly to prevent the fungus from recurring.
What Causes Fungus on Fiddle Leaf Figs?
Fungus can be a major problem for fiddle leaf figs, especially when the plant is kept in a warm and humid environment.
Fungal pathogens can enter the plant through wounds in the leaves and stems, or can be spread through contaminated soil or water.
Common fungi that attack fiddle leaf figs include Botrytis, Pythium, Fusarium, Rhizoctonia and Phytophthora.
These fungi cause a variety of symptoms, including wilting, yellowing, and spotting of leaves, as well as root rot.
Climate changes and stress can also predispose the plant to fungal infections, making treatment and prevention essential for keeping your fiddle leaf fig healthy.
Removing Affected Leaves
When it comes to treating fungus on fiddle leaf figs, the first step is to remove any affected leaves.
This is important because it helps to prevent the spread of the fungus to other parts of the plant.
Its important to take the time to carefully remove the affected leaves, as careless removal can cause additional damage to the plant.
You should use clean and sterilized pruning shears or scissors to ensure that the disease doesnt spread further.
Once all the affected leaves have been removed, you can discard them in an appropriate manner.
Be sure to sterilize your tools before and after use to avoid spreading the fungus to other plants.
Sterilizing Pruning Tools
Treating fungus on a fiddle leaf fig is a delicate process, and its important to take the proper precautions.
Pruning the affected leaves is an important part of the process, as it will help reduce the spread of the fungus.
Before pruning, you should always sterilize your pruning tools to help reduce the spread of the fungus.
This can be done by wiping the blades of the pruning tool with rubbing alcohol or a solution of one part bleach and nine parts water.
This will help eliminate any bacteria or germs that may be on the pruning tool.
Additionally, be sure to disinfect any gloves or other protective wear you may be wearing while pruning.
This will help ensure that the fungus does not spread further.
Increasing Air Circulation and Humidity
Increasing air circulation and humidity around a fiddle leaf fig is essential for treating fungus and preventing further spread.
Good air circulation helps to keep the plant dry and discourages fungal growth.
You can improve air circulation around the plant by placing it in a space away from other plants, curtains, or furniture.
You can also use a fan to circulate the air around the plant, ensuring that all areas of the plant are exposed to air flow.
Increasing humidity is also important for treating fungus.
By increasing the humidity around the plant, you create a less favorable environment for fungal growth.
You can increase humidity in the area by placing a humidifier near the plant or misting the plant with a spray bottle.
Additionally, you can group plants together to create a microclimate with higher humidity.
This will help keep the foliage of your fiddle leaf fig free of fungal infections.
Reducing Water and Fertilizer
Reducing water and fertilizer is an important part of treating fungus on fiddle leaf figs.
Too much water and fertilizer can promote fungal growth and create an environment that is more conducive to the spread of the fungus.
When treating a plant for fungus, it is important to reduce the amount of water and fertilizer you are using.
When watering your fiddle leaf fig, use a light hand and water only when the soil is dry.
As a general rule, it is best to water the plant when the top inch or two of soil is dry.
If you are unsure when to water, use your finger to feel the soil and check for moisture.
Additionally, it is important to avoid over-watering, as this can lead to root rot, which can further promote fungal growth.
When it comes to fertilizer, it is also important to reduce the amount you are using.
If the plant is actively fighting a fungal infection, it is best to avoid fertilizing altogether, as this can promote further fungal growth.
If you decide to fertilize, use a light hand and only fertilize sparingly and during the growing season.
Additionally, make sure to use a fertilizer that is specifically designed for houseplants and avoid fertilizers that are high in nitrogen, as this can promote fungal growth.
Finally, if you are unsure about how much water and fertilizer to use, it is best to consult a professional.
A professional can help you determine the best course of action for your particular plant and give you advice on how to best treat the fungus.
What Fungicides Work Best?
When it comes to treating fungus on fiddle leaf figs, the most effective fungicides are those that contain neem oil, potassium bicarbonate, or sulfur.
Neem oil is a natural fungicide derived from the neem tree.
It works by disrupting the growth of fungal cells, and it is safe to use on all types of plants.
Potassium bicarbonate is a chemical fungicide that works by lowering the pH of the soil, making it inhospitable to fungal growth.
Sulfur is a broad spectrum fungicide that works by coating the plants leaves and inhibiting the growth of fungal spores.
All of these fungicides should be used according to the manufacturer’s directions and should be applied to both the leaves and the soil.
Additionally, when using any fungicide, it is important to make sure that you are using the correct dilution rate, as too much can damage the plant.
