Q.Dying bottle brush tree
As it looks like my tree is slowly dying while full of blooms, should I just trim back the branches? There are new shoots near the base of the trunk but there is also algae. It rains a lot here in south Louisiana. Also some of the bark on the branches has cracked open. Any advice would be greatly appreciated.

Your tree may be suffering is the soil is poorly draining.
Well drained soil is key to your trees health.
