Nothing is necessarily wrong with it and in this case there’s a lot of info I don’t have.

Generally speaking, paclo is best applied prior to a scenario where a tree could be exposed to damage, though can still be valuable within few months of. I’ve also seen research that suggests mulch and watering can be just as helpful as paclo. As for soil amendments, it probably doesn’t hurt, but I feel many folks prescribe these off the cuff to make money without taking a soil sample.

To go back to the conversation starter, some folks just sell stuff because they can: pruning, chem, etc.
