By

Fiddle Leaf Figs (Ficus lyrata) are a popular type of houseplant known for their large, glossy leaves.

They are native to tropical climates, requiring warm temperatures and high humidity to thrive.

One of the most common problems with Fiddle Leaf Figs is white spots on the leaves.

Here is a quick guide on how to treat white spots on your Fiddle Leaf Fig.

What Causes White Spots on Fiddle Leaf Fig and How To Treat Them

Fiddle Leaf Fig plants are susceptible to several problems, including fungal diseases, pests, and environmental stressors.

One of the most common problems is white spots on the leaves and stems.

Several different factors can cause white spots.

Here are some of the most common causes of white spots on Fiddle Leaf Fig plants:

Powdery Mildew

Fiddle Leaf Fig plants are susceptible to a number of different diseases, including root rot, bacterial leaf spot, and powdery mildew.

The most common disease that causes white spots is powdery mildew.

Powdery mildew is a type of fungal infection that can occur in many plants, including Fiddle Leaf Fig plants.

The fungus thrives in humid conditions and produces a white or gray powdery substance on the surface of the leaves.

The first signs of powdery mildew are small, white spots on the Fiddle Leaf Fig leaves.

The spots will become larger as the infection progresses, and the Fiddle Leaf Fig leaves will begin to curl and turn yellow.

Powdery mildew is a severe problem that can eventually kill your Fiddle Leaf Fig plant if it is not treated.

You can know if your plant has powdery mildew if the leaves have white powder on them that can easily rub off.

How To Get Rid of Powdery Mildew on Fiddle Leaf Fig Plants

If you think your Fiddle Leaf Fig plant has powdery mildew, it is essential to take action immediately.

Powdery mildew is a severe problem that can kill your plant if it is not treated.

There are several different ways to get rid of powdery mildew on Fiddle Leaf Fig plants.

Here are some of the most effective methods:

1. Improve Air Circulation Around Your Plant

Powdery mildew thrives in humid conditions.

Improving the air circulation around your plant will help to reduce the humidity and make it harder for the fungus to spread.

You can improve the air circulation by placing a fan near your plant or moving it to a well-ventilated area.

2. Remove Infected Leaves

One of the best ways to get rid of powdery mildew is to remove the infected leaves from your plant.

This will help reduce the amount of fungus on your plant and prevent it from spreading.

You can remove the leaves by hand or with pruning shears.

3. Treat Your Plant With a Fungicide

If the problem is severe, you may need to treat your plant with a fungicide.

There are several different fungicides available, so be sure to choose one specifically designed for powdery mildew.

Follow the instructions on the fungicide carefully and only use it as a last resort.

4. Make a Homemade Fungicide

You can also make your own fungicide at home with ingredients that you probably already have in your kitchen.

One of the most effective homemade fungicides is made with baking soda and water.

Mix together 1 tablespoon of baking soda with 1 quart of water.

Spray the mixture on your plant, covering all of the infected areas.

Do this once a week until the problem is gone.

How To Prevent Powdery Mildew on Fiddle Leaf Fig Plants

The best way to deal with powdery mildew is to prevent it from happening in the first place.

Fungi thrive in humid conditions, so it is important to ensure that your plant is not too wet.

Water your plant only when the soil is dry and allow the excess water to drain away.

You should also avoid misting or watering your plant in the evening, as this will increase the humidity around your plant and make it more susceptible to powdery mildew.

In addition, make sure that your plant has enough light.

Fungi love shady, dark conditions, so giving your plant enough light will help to prevent the growth of fungi.

Finally, clean up any fallen leaves or debris from around your plant.

This will help to prevent the spread of fungi and other diseases.

Sunburn

Fiddle Leaf Fig plants are native to tropical climates and require bright indirect light to thrive.

However, too much direct sunlight can cause the Fiddle Leaf Fig leaves to develop white spots.

The spots are tiny burns caused by the sun’s rays.

If your Fiddle Leaf Fig plant is in a sunny spot, you may notice that the leaves have developed yellow or brown spots.

These are sunburns and will eventually turn white.

How To Treat Sunburn on Fiddle Leaf Fig Plants

If you think your Fiddle Leaf Fig has developed sunburn, you can do a few things to help it recover.

1. Move Your Plant to a Shadier Spot

The first and most important thing you need to do is move your plant to a shadier spot.

If possible, place it in an east-facing window where it will get morning sun but will be protected from the harsh afternoon rays.

2. Add a Layer of Protection

You can also help protect your plant from further sun damage by adding a sheer curtain or blind to the window.

This will filter the light and prevent the leaves from getting burned.

3. Give Your Plant Time to Recover

Sunburned leaves will eventually turn white and may even fall off.

This is normal, and your plant will eventually grow new leaves.

In the meantime, keep an eye on your plant and water it regularly.

4. Avoid Fertilizing

Fertilizing your plant while recovering from sunburn can do more harm than good.

Wait until the leaves have fully recovered before fertilizing your plant.

5. Water Properly

Watering your plant properly is essential, but it is crucial when your plant is recovering from sunburn.

Be sure to water only when the soil is dry and avoid getting the leaves wet, as this can cause further damage.

How To Prevent Sunburn on Fiddle Leaf Fig Plants

The best way to prevent sunburn on your Fiddle Leaf Fig plant is to give it the right amount of light.

Place it in a spot where it will get bright, indirect sunlight, and be sure to protect it from direct sunlight.

You can also help protect your plant by adding a sheer curtain or blind to the window.

This will filter the light and help to prevent sunburn.

Environmental Stress

Fiddle Leaf Fig plants are sensitive to changes in their environment.

If the temperature suddenly drops or rises, the plant may develop white spots on the leaves.

Other environmental stressors, such as drafts, can also cause white spots.

You can tell if your plant is experiencing environmental stress if the leaves are wilting or the spots are accompanied by other symptoms, such as yellow leaves.

How To Treat Environmental Stress in Fiddle Leaf Fig Plants

If you think your plant is experiencing environmental stress, you can do a few things to help it recover.

1. Remove the Plant From the Stressful Environment

You need to find out what is causing the stress and remove the plant from the source.

If the temperature has dropped suddenly, move the plant to a warmer location.

If there is a draft, move the plant away from the windows or doors.

2. Make Sure the Plant Is Getting Enough Water

Environmental stress can cause the plant to lose water faster than usual.

Make sure the plant is getting enough water by checking the potting soil regularly.

The soil should be moist but not soggy.

3. Increase the Humidity Around the Plant

You can increase the humidity by misting the Fiddle Leaf Fig leaves or placing the plant on a pebble tray.

4. Give the Plant Some Time To Recover

After removing the plant from the stressful environment and increasing the humidity, give the plant some time to recover.

Most white spots should start to fade within a few weeks.

5. Prune Off Affected Leaves

If the leaves are severely damaged, you can prune them off.

Use sharp, clean shears, and disinfect them before and after use.

Prune back to a healthy node or leaf.

This will help the plant to focus its energy on new growth.

How To Prevent Environmental Stress in Fiddle Leaf Fig Plants

The best way to prevent environmental stress is to make sure the plant is in a stable environment.

Avoid sudden temperature changes and drafts, and ensure the plant has enough humidity.

You can also help protect your indoor plant by acclimating it slowly to new environments.

For example, if you move the plant to a new location, do it gradually for days or weeks.

This will give the plant time to adjust and will help to prevent stress.

Pests

Fiddle Leaf Fig plants are susceptible to several different pests, including mealybugs, scale insects, fungus gnats, and spider mites.

The most common pest that causes white spots is mealybugs.

Mealybugs are tiny, sap-sucking insects that feed on the leaves of plants.

They excrete a sticky substance called honeydew, which can cause sooty mold to grow on the plant.

The first signs of mealybugs are small, white spots on the leaves.

As the infestation progresses, the spots will become larger, and the leaves will begin to yellow and curl.

Mealybugs are a severe problem that can eventually kill your Fiddle Leaf Fig tree if they are not treated.

How To Treat Pests on Fiddle Leaf Fig Plants

If you think your plant has pests, you can do a few things to get rid of them.

1. Isolate the Plant

The first step is to isolate the plant from other plants.

This will prevent the pests from spreading.

2. Inspect the Plant Closely

Take a close look at the plant, paying particular attention to the undersides of the leaves.

If you see any small, white bugs, they are probably mealybugs.

3. Use Insecticidal Soap or Neem Oil

You can treat mealybugs with insecticidal soap or neem oil.

They are both effective and safe for use on Fiddle Leaf Fig plants.

Use a cotton swab or a soft brush to apply the soap or oil to the bugs.

Be sure to get under the leaves and in all the nooks and crannies where the bugs like to hide.

4. Repeat as Necessary

You may need to treat your plant several times before the bugs are gone.

Be sure to follow the instructions on the insecticidal soap or neem oil you are using.

5. Discard Infested Plant Material

Once you have treated the plant, remove any infested leaves or stems.

Place them in a plastic bag and throw them away.

Do not compost them!
