Brown Leaf Edges on African Violet: Fertilizer Burn or Other Causes?

Jena's two-month-old African violet developed tan-brown edges on leaves, spreading to younger leaves. She suspected over-fertilization, leached the soil, but symptoms persisted. She used filtered lukewarm water and bottom-watering.

Differential Diagnosis

• Fertilizer burn: Usually shows as brown leaf tips/edges, but leaching should help
• Cold water damage: Ruled out by using lukewarm water
• Low humidity: Brown crispy edges from dry air
• Salt buildup: From fertilizer or tap water minerals
• Root issues: Impaired uptake despite proper watering

Next Steps

Since leaching didn't help and cause is unclear, consult the African Violet Society of America (avsa.org)—they offer free photo diagnosis. Consider repotting in fresh, light mix (1/3 peat, 1/3 perlite, 1/3 vermiculite) if roots appear healthy.
