Diagnosing Rust-Like Spots on Overwatered Bougainvillea: Fungicide and Cultural Correction

Orange Spots on One Bougainvillea in Mexico

Excessive water causes rust fungus. This plant gets "lots of water"—the likely culprit.

Fix

• Reduce watering dramatically.
• Spray broad‑spectrum fungicide.
• Cut back on fertilizer (too much N = leaves, not bracts).

Bougainvillea thrives on neglect—less water, less food, more color.
