Fiddle Leaf Fig Sunburn — When Too Much Light Damages the Leaves
Fiddle Leaf Fig (Ficus lyrata)
Symptoms
- tan or bleached patches on leaves
- dry papery areas
- browning on sun-facing leaf surface
- crispy areas near windows
- pale washed-out areas
Causes
Direct sunlight through glass
Glass acts as a lens that concentrates UV radiation and heat. A Fiddle Leaf Fig placed within 1 foot of a south or west window in summer can receive enough direct sun to bleach and scorch the chloroplasts in its large leaves. The damage is most severe in afternoon sun (west windows) and summer when the sun angle is higher.
Sudden move from shade to bright light
A plant that was in low light and is suddenly moved to bright indirect or direct light has leaves that haven't built up the UV-protective compounds (flavonoids, carotenoids) that high-light plants accumulate. These shade-adapted leaves are far more susceptible to bleaching than the same species that has been acclimated to bright conditions gradually.
Reflected light amplification
Light reflecting off white walls, glass buildings outside the window, or light-colored surfaces near the plant can amplify the effective light intensity significantly. A spot that seems suitable may actually deliver far more light than expected due to reflection.
How to Fix It
- 1
Move the plant away from direct sun or filter the light source with a sheer curtain. The FLF needs bright indirect light, not direct sun. A position 2–4 feet back from a south or west window, or directly in front of an east window, is usually ideal.
- 2
Sunburned areas of leaves will not recover their green color — the chloroplasts are permanently damaged. These leaves can be left on the plant (they still contribute some photosynthesis) or trimmed off if cosmetically unacceptable.
- 3
If the plant was recently moved from low light to high light, acclimate it gradually over 2–4 weeks: start it 4 feet from the window and move it 6 inches closer every 4–5 days until it reaches its final position.
Prevention
- Avoid placing Fiddle Leaf Figs within 1–2 feet of south or west windows without a sheer curtain buffer in summer months.
- When moving a FLF from a lower-light environment to a brighter spot, acclimate gradually over 2–4 weeks.
- Monitor the plant closely in late spring as the sun moves higher in the sky — a spot that was safe in winter may deliver too much direct light in summer.
