Bougainvillea Freeze Damage.

2024 Update: I've lost several Bougainvilleas to freeze damage throughout the years and I don't want to lose anymore. When it gets too cold, their leaves and roots may get frost damage. When their roots get frost damage they don't seem to make a comeback.

But it is possible for Bougainvilleas to recover after frost damage, I've seen mine make a comeback.

I'll just have to be more vigilant about protecting their roots from the freezing temperatures in the future.

• I've read Bougainvilleas can tolerate temperatures above 32F,  but 40F is going to be my personal cutoff point. When temperatures are predicted to go below 40F, I'll cover my Bougainvilleas.
• I'll wrap them in a cozy frost cloth or blanket to help protect their leaves.
• I can add a layer of much to help protect the roots from frost damage.

Two of them have a few pink bracts, but not very many. You can see the frost damaged branches on this one.

Bougainvilleas Need Fertilizer

I'll begin the routine of pruning and fertilizing them this spring.

One of the Bougainvilleas Didn't Recover   

The White Bougainvillea never recovered from frost damage, The roots on this one must have gotten damaged.
