Yellow African Violet Leaves: Causes and Cures for Yellowing Foliage

Natural Aging

Lower leaves naturally yellow and drop after about a year, making room for new growth. This is normal and not a cause for concern.

Common Causes of Yellowing

Water Issues

Water on leaves causes yellow or bleached necrotic spots (ring spot). Water temperature extremes (warmer or colder than leaf) collapse leaf cells, causing discoloration. Water under the leaves using room-temperature water. Special long-spout watering cans help.

Lighting

African violets need bright, indirect light. Best location: 3 feet from a southeast or west window. Too little light (e.g., deep in a room or under office lights) causes yellowing leaf edges. Move to a brighter indirect location to recover.

Fertilizing

Lack of fertilizer causes yellowing. Use a fertilizer formulated for African violets, diluted per directions. Feed monthly during growing season. Prevent salt buildup by drenching soil 4 times per year.

Care for Yellowing Plants

• Repot at least every 2 years in fresh mix (sphagnum peat moss with vermiculite; avoid traditional potting soil).
• Increase humidity: place pot on a saucer of pebbles with water (change water every few days to prevent gnats).
• Pinch off old leaves and spent blooms to encourage new growth.

With proper light, water, and occasional feeding, your African violet will return to healthy green foliage.
