Q.Bottle Brush Tree
My bottle brush tree is maybe 6 years old, 6 feet tall, and has always been beautiful. We had a colder than usual winter in East Texas with several hard freezes. It looks like it is dead but new growth is coming from the base of the tree. Should I trim the tree from the top down to the new growth or just leave it alone and maybe the dead branches and leaves will falloff? What do I do?

Yes, you will want to trim this back until you reach living tissue. It will be very easy to tell what is dead, and what is alive. Only trim off what is dead, and it will likely recover fairly quickly.
