My bougainvillea plant died, I thought, during the last freeze even though I had covered it with several sheets.
However, next time I will definitely use blankets with Christmas lights (thank you, Red). It was about
7 feet tall and spread across by courtyard will back wall.
I left it, did not trim it, and it soon began to recover and then I trimmed it. It grew with vengeance. It is in full sun all day.
Here is a series of helpful videos on bougainvilleas:
