Bougainvillea Bloom Cycles and Care

Cyclical blooming (flowers for 1–2 weeks, then a 2–3 week rest) is normal for bougainvillea. Keep watering consistent—avoid extremes of wet or dry. Feed regularly with a bloom‑booster fertilizer (high middle number) and sprinkle a cup of Epsom salts (magnesium sulfate) around the base to strengthen the plant.
