my out door ficus trees looks so bad, how do I know if they dead?

Question

this season on Phoenix, is being so bad for the trees, the temperatures drooped so the ficus looks dead. What I can do with it?

Answer 1

Scrape a bit of the bark away on the trunk, and if it is green underneath, then the tree is still alive.
Put it in shelter, until spring then give it a gentle prune. Should come back to life again.
If it is brown underneath the bark, then it is dead.
Then throw it away.

Answer 2

If it is still green underneath the outer bark, the ficus is still alive. if not, it is very probably dead. if in a pot, put in warmer place. if not, nothing to be done except cutting away everyting that is dead.
