Start with moisture and the damage pattern
Brown tissue will not become green again. Your aim is to stop new damage. Photograph the whole plant and an affected leaf, then check moisture below the surface, drainage and recent changes in light or feeding.
Dry mix and a light pot
If the root ball is dry, water thoroughly and let it drain. Check that water reaches the mix instead of running only through a gap at the edge. Review how you will check the pot next time; do not replace a missed watering with permanently wet compost.
Wet mix does not rule out water stress
Roots in poor condition may not supply leaves adequately. If wilting or browning continues while the mix stays wet, inspect drainage first. Persistent decline or a soft base is a reason to inspect the root ball carefully.
Retain firm roots; remove clearly soft, decaying tissue with clean tools if rot is present. Repot into fresh, well-drained mix in a pot suited to the remaining roots. Do not cut every brown root or prescribe complete drying as a universal cure. Seek help if little healthy root tissue remains.
Check heat and dry air
Look for a radiator or air outlet aimed at the plant and measure nearby humidity if dry air is suspected. The width of a brown margin cannot reliably distinguish humidity trouble from root or watering problems.
Adjust the location or humidity only when the conditions support that explanation. A humidifier is not a substitute for checking the pot.
Review feeding and deposits
Check product strength, frequency and any fertiliser already in the compost. Surface deposits can support a salt-buildup concern, but are not a complete diagnosis.
Pause extra feeding while investigating. Leaching a freely draining pot can reduce salts; repeatedly flushing a saturated pot with damaged roots is not a sensible first step. Correct drainage or replace unsuitable mix when necessary, then follow the feed label rather than an arbitrary stronger dose.
Damage after stronger sun
Consider scorch if patches developed after exposure increased and mainly affect the exposed side. Filter harsh light and acclimatise gradually to a brighter position. Keep checking for new damage rather than expecting old patches to disappear.
An isolated bruise or spreading spots?
Check for repeated contact with a wall, window or passing people. A stable damaged patch may need no treatment. Keep useful green leaf tissue rather than removing every imperfect leaf.
If lesions expand or appear elsewhere, use the leaf-spot checks. Inspect undersides for pests as well; neither a brown edge nor a yellow halo identifies a pathogen.
Keep a short record
Compare photographs weekly and note moisture checks, not only watering dates. Continuing leaf loss, stem collapse or spreading lesions needs closer investigation. For routine care, return to the fiddle-leaf fig guide.
