Why African Violet Buds Turn Brown and White Dust Appears

A violet in a coffee mug (plant extends 3+ inches over the rim) has massive buds that turn brown before opening. Bottom leaves pale, and white dust forms on leaves near blooms — some buds dry out before forming.

Diagnosis

• Bud blast (browning): Caused by low humidity. Fix by placing pot on pea gravel with water (not touching pot).
• Pot too small: Pot should be 1/3 plant width. Violets bloom best when slightly root-bound.
• White dust: Likely powdery mildew — caused by stagnant air in humid conditions. Paradoxically, the plant needs humidity for buds but air circulation to prevent mildew.

Treatment Plan

1. Increase humidity with gravel tray.
2. Repot into correctly sized container.
3. Spray lightly with Lysol to combat mildew.
4. Add a gentle fan for air circulation.
