Bougainvillea Not Blooming Near Hilton Head: Water and Fertilizer Balance

Color Comes from Stress

Lush, green, non-blooming bougainvillea in SC usually gets too much water and nitrogen. Bracts color best under mild drought and low nitrogen.

Adjustments

• Cut irrigation back significantly.
• Use low-N, high-P fertilizer (e.g., 5-10-10) or bloom booster.
• Cooler fall temperatures naturally encourage color.

Hardiness Note

Hilton Head (Zone 8b) is marginal. Protect from hard freezes; expect dieback but regrowth from base.
