It's not impossible to fix, take heart! Georgia orange clay subsoil left by the developer here. Among the many sources of mulch and organic adds for every year is hay by the huge roll, and wood chips dumped by the state DOT (there's usually a number to call online, then you get transferred a bit, then get on a waiting list, then you call every few weeks, but it's free). It took several years of this to see a big difference.
Also never work wet clay soils!
Wide row beds that are never walked on.
Soil tests! My ph was 4.8! Waaaaay too acid.
