                                                          If your jacaranda tree is peeling, has falling bark, and has lost it's leaves it could simply be molting. Next spring a new better tree will emerge. However, it could also be from over-watering due to local weather patterns. In Addition, check under the fallen leaves and below the falling bark for tiny insects; spray if any are found.
