Q.How Should I Care For My Bottle Brush Tree Now That The Excessive Cold Has Burnt The Tree.
The extreme unusual temperatures in Texas 2 weeks ago burnt my 3 bottle brush trees. They were at least 6 feet tall. I had to go trim them because the ice and snow were too heavy to support the limbs. Now they are really burnt and I’m wondering if they will come back. And is it okay to trim them further in the hopes that they will rebound. They are 5 year old trees and the cold was never a problem before now. We live in Bastrop, Texas which is normally mild.

We've had a number of questions like yours because of the unexpected cold snap. If your temps didn't go below 10 or 15 degrees F., your shrub may have survived. You can scratch off some of the wood on a branch to see if it is green below. If so, it is still alive. If not, it may regrow from the roots, in which case you can do a hard prune. (I would wait till after it flowered to do any major pruning.) These articles should help.
