Bougainvillea Plants
Q.

My bougainvilleas got hit by frost (around 28 degrees possibly). Should I cut them back when it warms up?

We're located just outside Casa Grande and have had a few hard freezes. I currently have them covered but the blooms are looking very sad. If I cut them back next week when it warms up will they survive?

It's best to wait until all danger of frost is over, which is end of February to be safe. The frost damaged and dried foliage, even though ugly, provides some protection for a deeper freeze that may kill the stems. Or the better alternative is to cover the plant when a freeze is predicted, like you would for citrus.
