Fiddle Leaf Fig problems and how to fix them
6 common issues for Ficus lyrata. Click any problem below to jump to its diagnosis and treatment.
Most Fiddle Leaf Fig problems trace back to one of three things: light, water, or humidity. Before assuming the worst, double-check the basics in our Fiddle Leaf Fig care guide. If conditions look right and the symptoms persist, work through the matching problem section below.
Brown spots
Symptoms
- Round or irregular brown patches on the leaves
- Spots may have a yellow halo around them
- Some spots stay small; others grow over weeks
- Spots feel either dry and crispy or soft and mushy
Most likely causes
- Fungal infection. Wet leaves combined with poor airflow allow fungal spots to take hold. Common on Fiddle Leaf Fig and Rubber Plant. Spots are usually irregular with yellow halos.
- Bacterial infection. Often shows as soft, mushy, dark spots that smell unpleasant. Spreads quickly between leaves.
- Sunburn. Direct sun through unfiltered windows can scorch leaves. Spots are dry, crispy, and only on leaves that face the sun.
How to fix
- Identify the cause: dry crispy spots = sunburn or underwatering, soft mushy spots = bacterial, irregular dry-with-halo = fungal.
- Remove affected leaves with sterile scissors. Do not compost — bag and bin.
- For fungal issues, increase airflow and stop misting. Apply a copper-based fungicide if spots continue spreading.
- For sunburn, move the plant back from the window or filter the light with a sheer curtain.
- Sterilise scissors between cuts with rubbing alcohol to avoid spreading infection.
How to prevent next time
- Water at the soil level, not on the leaves
- Ensure good air circulation — avoid overcrowding plants
- Filter direct sun with a sheer curtain for plants that prefer indirect light
Leaf drop
Symptoms
- Leaves fall off — sometimes still green — without obvious yellowing first
- Often occurs after a move, repotting, or sudden environment change
- May be limited to lower leaves or be widespread
Most likely causes
- Stress from change. Fiddle Leaf Fig and Rubber Plant are notorious for dropping leaves after being moved, repotted, or exposed to drafts. They acclimate slowly.
- Watering inconsistency. Dramatic swings between dry and wet stress the plant. Leaves drop as the plant tries to reduce its water needs.
- Light shock. Moving from bright to dim, or vice versa, can trigger leaf drop within days. The plant cannot support all its leaves on the new light budget.
How to fix
- Stop interfering. Do not move, repot, or fertilise. Let the plant settle for 2–4 weeks.
- Maintain a steady watering rhythm. Do not let the soil swing from soaking wet to bone dry.
- Keep the plant away from drafty windows, doors, and AC vents.
- New leaves emerging after a stress period is the signal that the plant has acclimated.
How to prevent next time
- Acclimate plants gradually when changing locations — move them in stages over 2 weeks
- Avoid repotting in winter when growth is slow
- Stable conditions matter more to these plants than perfect ones
Yellow leaves
Symptoms
- Older lower leaves turn yellow first, sometimes one at a time
- Yellowing spreads from the leaf base outward, or appears as patches
- Soil feels persistently wet, or has been bone-dry for several weeks
- Yellow leaves may feel soft (overwatering) or papery (underwatering)
Most likely causes
- Overwatering. The most common cause. Roots sit in waterlogged soil, lose oxygen, and start to rot. The plant cannot move water and nutrients up to the leaves, so they yellow and drop.
- Underwatering. If the soil is severely dry and pulled away from the pot edges, the plant is shedding leaves it can no longer support. Yellowing under drought is usually accompanied by crispy edges.
- Natural leaf drop. Older lower leaves yellow and fall as the plant matures. One yellow leaf every few months on an otherwise healthy plant is normal — not a problem.
How to fix
- Check the soil 5cm deep with your finger. Wet → underwater diagnosis. Dry past the second knuckle → underwater diagnosis.
- If overwatered, hold off watering and move to a brighter spot to speed soil drying. Tip the pot to drain any pooled water.
- If underwatered, soak the pot in a basin of room-temperature water for 20 minutes, then let drain.
- Remove yellow leaves only after the rest of the plant stabilises — they will not turn green again, but cutting them off too early stresses the plant further.
- If many leaves yellow within a week and stems feel mushy, unpot and inspect the roots for rot.
How to prevent next time
- Water by checking the soil, not by the calendar
- Use a pot with drainage holes — decorative pots without drainage are root rot waiting to happen
- Cut watering by 30–50% in winter when growth slows
Root rot
Symptoms
- Stems feel soft or mushy at the soil line
- Sour or rotten smell from the soil
- Multiple leaves yellow and drop within a week
- Soil stays wet for more than 7–10 days even in warm conditions
- Black or brown roots that fall apart when touched (visible only after unpotting)
Most likely causes
- Chronic overwatering. The single biggest killer of houseplants. Soil that never fully dries deprives roots of oxygen, killing them and inviting fungal pathogens.
- Pot without drainage. Decorative ceramic pots without drainage holes trap water at the bottom. Even with careful watering, salt and excess water build up over months.
- Compacted or peat-heavy soil. Old soil compresses and holds water. Soil mixes that are too peat-heavy stay wet for a long time. Tropicals especially need a chunky, airy mix.
How to fix
- Unpot the plant immediately. Gently shake off as much soil as possible.
- Inspect the roots. Healthy roots are firm and white or tan. Rotted roots are black, brown, or grey, and slip apart between your fingers.
- Cut off all rotted roots with clean, sharp scissors. Leave only the firm, healthy ones — even if you remove 80%.
- Dust the cut roots with cinnamon (a mild antifungal) or let them air-dry for an hour.
- Repot in fresh, dry, well-draining mix in a clean pot with drainage holes. Use a pot only one size larger than the remaining root mass — too much soil holds too much water.
- Hold off watering for 5–7 days after repotting, then water lightly. Move to bright indirect light.
How to prevent next time
- Always use pots with drainage holes
- Let the top 2–5cm of soil dry between waterings, depending on the plant
- Repot every 2–3 years in fresh, chunky, airy mix
Sunburn
Symptoms
- Round or irregular brown patches on the leaves
- Spots may have a yellow halo around them
- Some spots stay small; others grow over weeks
- Spots feel either dry and crispy or soft and mushy

- Ensure good air circulation — avoid overcrowding plants
- Filter direct sun with a sheer curtain for plants that prefer indirect light
Spider mites
Symptoms
- Fine webbing on the underside of leaves, especially where leaves meet stems
- Tiny pale or yellow stippling dots all over the leaves
- Leaves turn dusty-looking, then dry and drop
- Worsens fast in warm, dry conditions
Most likely causes
- Low humidity. Spider mites thrive in dry indoor air. Heated rooms in winter are their favourite environment.
- Hitchhiking on a new plant. A new plant from the nursery often brings mites home with it. They spread to other plants within days.
How to fix
- Isolate the affected plant immediately so mites do not spread.
- Take it to the shower or sink. Spray the entire plant — especially leaf undersides — with strong, lukewarm water for 2–3 minutes. This dislodges most mites.
- After drying, spray with insecticidal soap or a 1:10 mix of mild dish soap and water, covering both sides of every leaf. Repeat every 5–7 days for 3–4 weeks.
- Wipe down the pot and the area where the plant was kept — mites can hide there.
- Raise humidity around the plant. Mites cannot reproduce well above 50% humidity.
How to prevent next time
- Inspect new plants for two weeks before placing them near others
- Mist or use a humidifier in dry winter months
- Wipe leaves monthly with a damp cloth — disturbance prevents establishment
