Troubleshooting Yellow Leaf Edges on African Violets

Diagnosing the Yellow Border

A thin yellow margin (⅛ inch) on 70% of leaves suggests environmental stress. Common causes include:

• Excess direct sun or heat – leaves may also curl or dry at edges.
• Water quality – chlorine, fluoride, or softened water.
• Fertilizer buildup – salts accumulating at leaf margins.
• Low humidity – especially with warm temperatures.
• Cold drafts – recent exposure to chilly air.

Information Needed for Precise Diagnosis

Please provide details on:

• Watering frequency and method (top vs. bottom)
• Fertilizer type and schedule
• Exact light exposure (direct sun? sheer curtain?)
• Recent moves or temperature changes
• Whether leaf edges are curled, dry, or just yellow

Immediate Actions

• Move away from any direct sun or heat sources.
• Use room-temperature distilled or rain water.
• Flush soil with clear water to leach excess salts.
• Increase humidity with a pebble tray or humidifier.

With more details, a targeted solution can be recommended.
