I have had this mangrove for several years and it has grown nicely.

Unfortunately it dropped all it's leaves a several weeks ago.

I have given it time to recover but there has been no new growth. I am fairly certain that the roots are still alive. What should I do? Should I trim it back? If yes, to where?
