Why Bougainvillea Blossoms Drop and How to Restore Blooms

Understanding Bougainvillea Flower Drop

Sudden loss of colorful bracts (often mistaken for flowers) usually signals overwatering. Bougainvillea thrives on neglect—less water, poor soil, and heat stress actually enhance color.

Immediate Steps

• Stop overwatering. Let the soil dry between waterings.
• Apply balanced granular fertilizer to support recovery.
• Hold off on heavy pruning. The plant will regenerate bracts on its own.

Key Insight

The true flowers are tiny white centers; the showy "blossoms" are modified leaves called bracts. Stress triggers bract production. Once conditions stabilize, new color will return.
