Brown Spots on Fiddle-Leaf Fig?

The common causes, and how to tell them apart.

Brown spots are the fiddle-leaf fig's most-searched problem, and the look tells you the cause. Fungal or bacterial leaf spot makes dark spots with a yellow halo, sunburn leaves dry bleached-brown patches on the sunny side, and edema from overwatering in low light raises corky bumps underneath.

FAQ

Are brown spots on a fiddle-leaf fig serious?
It depends on the cause. Spreading spots with a yellow halo are a leaf-spot infection worth acting on; dry sunburn patches and edema bumps are cosmetic once you fix the light or watering.
Should I cut off spotted leaves?
Remove badly infected leaves to slow a spreading leaf spot. A few cosmetic sun or edema marks can stay.
