Growing Bougainvillea in Tucson: Sun, Water, and Cold Tolerance

Full Sun, Minimal Water, No Frost

Bougainvillea in north Tucson dies from overcare. They need:

• Full, baking sun
• Water only when dry (overwatering kills)
• Protection below 30°F (they are semi-tropical)
• Lean soil (sandy is fine)
• 10-10-10 granular fertilizer twice a year

Stop Fussing

The biggest mistake is "fussing"—too much water, shade, or fertilizer. Plant in the hottest, driest spot and ignore it. That's how they thrive in Tucson.
