1. Overwatering

Mistake:

One of the biggest causes of brown spots on fiddle leaf figs is overwatering. If the soil stays soggy for too long, the roots begin to rot, leading to dark brown or black spots on the leaves. These spots typically start at the base of the leaf and spread outward. Overwatering also reduces oxygen availability to the roots, further weakening the plant and making it susceptible to bacterial infections. You may also notice a foul smell coming from the soil, indicating root rot. If not corrected, prolonged overwatering can cause leaves to turn yellow and drop off completely.

Solution:

Check the soil before watering – only water when the top 2 inches are dry.

Use well-draining soil with a mix of peat, perlite, and pine bark.

Ensure adequate drainage –Make sure the pot you use has drainage holes.

Water less frequently in winter since the plant’s growth slows down.

Avoid using pots without drainage holes as they can lead to water buildup.

2. Underwatering

Mistake:

On the other hand, not watering enough can also cause brown spots. If your fiddle leaf fig is dehydrated, the leaves will develop dry, crispy brown edges and may start curling. Underwatering can happen when you don’t stick to a consistent watering routine or if the environment is too dry. The plant relies on consistent moisture to function properly, and when it lacks water, it struggles to transport nutrients to the leaves. This results in a weak, stressed plant that becomes more susceptible to other problems such as pest infestations and nutrient deficiencies.

Solution:

Check soil moisture regularly using your finger or a moisture meter.

Water thoroughly until _extra water is removed from the pot’s bottom.

Increase watering frequency in warm seasons when the plant is actively growing.

Monitor how quickly the soil dries out to adjust your watering schedule.

3. Poor Drainage

Mistake:

Even if you water correctly, your fiddle leaf fig can still suffer if the soil doesn’t drain well. When excess water stays trapped, it suffocates the roots and leads to brown spots. Poor drainage can occur due to using the wrong type of soil or a pot without sufficient drainage holes. Compacted soil that retains too much moisture can also contribute to this issue. If your plant sits in stagnant water for too long, root rot can develop, which ultimately leads to leaf damage and brown spots spreading across multiple leaves.

Solution:

Repot in a container with drainage holes.

Use a well-draining soil mix in order to avoid retaining water. 

Avoid letting your plant sit in standing water in a saucer.

Consider adding perlite or sand to improve soil aeration.

4. Low Humidity

Mistake:

Fiddle leaf figs thrive in a humid environment, and if the air is too dry, the edges of the leaves can develop brown spots. This is especially common during winter when indoor heating reduces humidity. Dry air causes excessive moisture loss through the leaves, making them dehydrated and brittle. If the plant continuously loses more water than it absorbs, the leaves will weaken, curl, and develop brown edges. Additionally, dry conditions make the plant more vulnerable to pests like spider mites, which thrive in low humidity environments and can further damage the leaves.

Solution:

Increase humidity by placing a pebble tray filled with water under the pot.

Use a humidifier to maintain humidity levels between 50–60%.

Mist the leaves occasionally, but avoid overdoing it to prevent fungal issues.

Group plants together to naturally increase the surrounding humidity.

5. Direct Sunlight Burns

Mistake:

Fiddle leaf figs love bright, indirect sunlight, but too much direct sunlight can scorch their leaves, causing light brown or tan patches. If your plant is placed near a south-facing window without any filter, the harsh afternoon sun can burn the delicate leaves. This usually results in irregularly shaped brown spots that appear faded or dry. Over time, these damaged leaves may turn brittle and fall off. Sunburn occurs more frequently in summer when the sun’s intensity is stronger, especially if your plant has recently been moved from a lower light environment to a bright spot too quickly.

Solution:

Place your plant near a bright window with indirect light.

Avoid direct afternoon sun, especially in summer.

Use sheer curtains to filter harsh sunlight if necessary.

Gradually introduce your plant to brighter light to prevent shock.

6. Nutrient Deficiency

Mistake:

A lack of essential nutrients, especially nitrogen and magnesium, can cause weak, spotted leaves. Fiddle leaf figs need regular feeding to maintain their deep green color. Without enough nutrients, the leaves start to lose their vibrancy, and brown patches may develop due to stress. If your plant is growing in old or depleted soil, it may not receive the necessary minerals for proper development. Yellowing between the veins or slow growth is often a sign of nutrient imbalance. If left unaddressed, the plant will continue to weaken, leading to stunted growth and further brown spot formation.

Solution:

Feed your plant with a balanced liquid fertilizer (such as 10-10-10 or 3-1-2) every 4–6 weeks.

Use a slow-release fertilizer for a steady supply of nutrients.

Ensure proper soil pH (5.5–7) to help nutrient absorption.

Flush the soil occasionally to remove excess salt buildup from fertilizers.

7. Pest Infestation

Mistake:

Pests like spider mites, scale, and mealybugs suck the sap from fiddle leaf fig leaves, causing brown spots, yellowing, and leaf drop. These tiny insects are often hard to spot at first but can quickly multiply and weaken the plant. Spider mites, in particular, thrive in dry conditions and leave behind small brown or yellow dots, often accompanied by fine webbing on the leaves. Scale insects appear as small brown bumps along the stems and veins, while mealybugs look like tiny white cottony clusters. If left untreated, these pests can severely damage your plant, causing leaf discoloration and eventual death.

Solution:

• Check the undersides of leaves regularly for pests.
• Wipe leaves with a damp cloth to remove dust and small insects.
• Treat infestations with neem oil or insecticidal soap.
• Quarantine new plants before placing them near your fiddle leaf fig.

8. Fungal or Bacterial Infection

Mistake:

Brown spots that spread rapidly and have a yellow halo may indicate a fungal or bacterial infection caused by excessive moisture and poor air circulation. Fungal diseases like leaf spot can develop if water consistently sits on the leaves, leading to damp conditions that encourage fungal growth. Bacterial infections, on the other hand, can result from contaminated tools, infected plants nearby, or improper care. Infected leaves often show black or brown water-soaked spots that grow larger over time. If not managed quickly, the infection can spread to multiple leaves, weakening the plant and eventually leading to severe leaf drop.

Solution:

• Remove infected leaves immediately to prevent spread.
• Improve air circulation by placing your plant in a well-ventilated area.
• Water at the base of the plant instead of overhead to keep leaves dry.
• Use a copper-based fungicide if necessary.
• Avoid misting if fungal issues are present to reduce excess moisture.

9. Temperature Stress

Mistake:

Fiddle leaf figs are susceptible to abrupt temperature changes.Exposure to cold drafts, air conditioning vents, or heating units can cause stress, leading to brown spots and leaf drop. If your plant is placed near a frequently opened door in winter or close to a heating vent in summer, the rapid temperature fluctuations can shock the leaves. Extreme cold can cause leaves to develop dark brown, almost black, patches, while heat stress may result in dry, crispy spots. Keeping the plant in an environment where temperatures fluctuate too much will weaken it over time, making it prone to additional health issues.

Solution:

• Keep the plant in a stable temperature range (60–75°F).
• Avoid placing it near drafty windows, radiators, or AC vents.
• Move your plant gradually when changing locations to reduce stress.
• Use curtains or blinds to buffer against cold or heat exposure.

10. Repotting Shock

Mistake:

If you recently repotted your fiddle leaf fig and noticed brown spots, it may be experiencing transplant shock. This happens when the roots are disturbed too much during repotting. The sudden change in soil conditions and exposure to new environmental factors can cause stress, leading to leaf browning, wilting, or even leaf drop. Plants need time to adjust to their new pot, especially if their roots were pruned or broken during the process. If the plant is not handled with care, it can take weeks or even months to fully recover, slowing its growth and making it more susceptible to other problems.

Solution:Minimize root disturbance when repotting.

Use fresh, well-draining soil to support recovery.

Keep the plant’s care routine consistent to help it adjust.

Avoid fertilizing immediately after repotting to prevent additional stress.
