Why Isn’t My Bougainvillea Flowering?

A gardener in Auckland, New Zealand, has a healthy-looking bougainvillea that refuses to bloom despite minimal watering and no fertilizer.

Sunlight: Needs full sun; shade inhibits flowering.
Watering: Moderate water; avoid excessive moisture.
Fertilizer: No high nitrogen. If soil is poor, apply a balanced 10-10-10 once yearly.
Pruning: A light trim can stimulate blooming.
Seasonal differences: Compare this year’s conditions to last year’s.

Address these factors, and your bougainvillea should reward you with vibrant color.
