Bonsai Bougainvillea Flower Drop: Transplant Shock and Care Correction

Why All Flowers Fell Overnight

The sudden bloom drop after two days outdoors/indoors cycling indicates environmental shock – likely from temperature/humidity swings or the move itself. Bougainvillea bracts are sensitive to rapid changes.

Care Corrections Needed

• Water more than "very little" – Bougainvilleas need regular water when actively growing, just not soggy soil
• Full sun all day – not partial; they need 6+ hours direct sun for blooming
• Stable location – pick one spot (ideally outdoors) and leave it
• No fertilizer until new growth appears

Recovery Timeline

Give it several weeks in consistent conditions. New growth signals recovery. Then resume normal watering and full sun exposure. The day/night shuttle is stressful – choose outdoors if nights stay above 40°F.
