African Violet Flower Petals Drying at Edges: Thrips, Low Humidity, or Cultural Stress?

Common Causes

• Thrips: Tiny insects rasp petals, causing browning edges. Check with yellow sticky cards.
• Low humidity: Dry air desiccates delicate petal margins.
• Overhead watering: Water on flowers causes spotting and premature aging.
• Nutrient imbalance: Excess nitrogen or calcium deficiency.

Diagnostic Steps

1. Examine flowers with magnifier for tiny slender insects.
2. Increase humidity to 50-60% (pebble tray, humidifier).
3. Water only from below; avoid wetting blooms.
4. Switch to blossom-booster fertilizer (high phosphorus).
