Pruning Frost-Damaged Bougainvillea for Recovery and Bloom

How to Cut Back a Bougainvillea Hedge After a Hard Freeze

San Diego bougainvillea took a hit. Once frost danger passes:

Step-by-Step

1. Remove all frosted stems/foliage back to live wood (green under bark).
2. Rejuvenation prune (optional): Identify oldest ⅓ of main stems; cut to ~4 ft.
3. Clean up: Remove deadwood, crossing branches, awkward growth.
4. Shape for appearance, not uniform height.

After New Growth Starts

Pinch tips of ⅓ of new shoots when 6–8 in long to encourage bushiness.
