Most likely cause
Environmental shock is the top cause of sudden leaf drop. Fiddle Leaf Figs dislike change, and almost any disruption can trigger it. To confirm, ask what changed in the last 1 to 2 weeks.
Did you move the plant, even to another room? Did a window, vent, or door create a temperature swing or cold draft? Did the season shift the available light? If the drop started right after one of these, shock is the cause. The fix is patience and stability, not a new routine.
Other causes
Ranked from most to least common, with how to tell them apart.
- Overwatering or root rot: Lower leaves drop first, show dark brown spots, and the soil stays soggy. The stem base may feel soft.
- Underwatering: Leaves turn dry and crispy with browning edges, then drop. The soil is bone-dry and pulls away from the pot.
- Low light: Slow, steady drop with pale or leggy growth. The plant sits too far from a bright window.
- Cold drafts: Leaf drop near an AC vent, heater, or drafty window, often with darkened patches.
- Pests: Spider mites or scale cause spotting, stickiness, or webbing; check leaf undersides.
How to fix it
- Identify the trigger by reviewing what changed in the last two weeks.
- Choose one bright spot with indirect light and leave the plant there. Stop moving it.
- Move it away from vents, radiators, exterior doors, and cold windows.
- Check the soil. Water only when the top 2 inches are dry, then water thoroughly and drain fully.
- If soil is soggy and roots smell rotten, repot into fresh, well-draining soil and trim mushy roots.
- Inspect leaf undersides for pests and treat with insecticidal soap or neem oil if found.
- Wait 2 to 4 weeks. Stable conditions let the plant recover and push new growth.

|---|---|---|---|
| Soil | Soggy, stays wet | Bone-dry | Normal |
| Leaf look | Brown spots, lower leaves | Dry, crispy edges | Healthy but dropping |
