Winterizing Bougainvillea in Central Texas: Pot Up or Mulch Heavy

Two Strategies for Zone 8a

Central Texas freezes kill bougainvillea left unprotected in ground.

Option 1: Containerize and Bring In (Best)

1. Prune back hard (they respond well)
2. Dig root ball, pot in container
3. Keep as houseplant in bright window
4. Water sparingly, no fertilizer
5. Move out after last frost

Option 2: In-Ground with Heavy Mulch (Risky)

• Prune back
• Mulch root zone 6-12" deep
• Cover crown with frost cloth on freeze nights
• Only works if ground doesn't freeze solid

Bougainvillea is Zone 9-10. Central Texas is marginal. Containerizing is far more reliable.
