I placed a 5 trunk jacaranda into the ground after it had been potted as a pre-bonsai for 5-6 years.The second year after planting,I slappd the trunks several times with a baseball bat which rresulte in blooms from only one branch.The next year it faild to bloom again and another series of batting didn’t produce blooms.Have also tried heavy fertilization with bone meal and 2-10-10 fertilizer.Any suggestions would be appreciated.

No, these methods are very outdated, and not proven to get results, since nails are not made of the same materials that they were when this was an acceptable method. Depending on the material that the nail is made of, it can cause the very quick death of the tree.

Beating it with a bat will either cause disease from the tree having to repair so many spots, or cause it to halt growth due to stress.

Jacaranda trees are notorious for this behavior and Those actions will, further, prolong flowering, unfortunately.
