Q.Madagascar palm
We have a 6 foot tall Madagascar palm, planted outside, just went through a hurricane, the whole top has gotten soft and looks dead
Can it be saved?

The Madagascar Palm – Pachypodium lamerii – is actually a succulent related to plumerias. The fact that your plant is showing signing of softening indicates it likely is suffering from root rot.
In this case, it is not likely to survive. So sorry for this damage and the effects from the hurricanes.
