If this is a fresh transplant, then it is definitely going through transplant shock. It is not advised to plant in the heat, and it can result in the death of the plant.
Even though it would seem logical to water constantly in the heat, these trees are somewhat drought tolerant once they establish. There is a fine balance between keeping a young transplant watered well, and overwatered.
It is best to plant these when it is cool, but there is still a good chance that this will recover once the climate is right.
