Why Are My Plant Leaves Turning Brown?

Brown leaves can follow several different problems. Check whether the damage begins at the tips or margins, forms separate spots, or affects whole leaves, and compare old and new growth before deciding what the pattern means.

5 plant-specific answers connected to this symptom

What this symptom means

Brown tissue is an outcome, not a cause. Dry margins, distinct lesions, soft tissue, and whole-leaf decline point toward different diagnostic checks, so color alone is not enough to choose a treatment.

What to notice first

Crispy tips or margins versus separate spots or larger blotches
Older leaves, newer leaves, or one side of the plant affected first
Whether the pattern repeats on several leaves or remains isolated
Recent heat, cold, strong sun, dry or wet root-zone conditions, pests, or spreading lesions
