Some states, such as Alabama, charge sales tax on everything, including fruit trees and other food plants (and food, for that matter).
As for how to get them to stop doing such things, I think there are two options for you. The first, some sort of class action lawsuit which will make the lawyers involved very rich. The second, which applies specifically for you in Florida, is to contact Governor DeSantis's office and say that woke corporations are funding their wokeness by illegally charging taxes on red-blooded, America-loving Floridian patriots. That second option, given our current political climate, would probably lead to a speedy, if not messy, resolution to this issue.
