Since it is impractical to amend the entire area that the roots will ever need to penetrate, maybe "blend" the amended soil in the planting hole with the surrounding clay. If the transition from good to bad soil is gradual, the roots are more likely to make the transition from pampered soil to clay.

Good advice. And I left out using existing soil. That should be mixed with amendments. Some argue no amendments just local soil, but I disagree. But I also do not like to get in religious like peeing contests about it. If that trips yer trigger - fine,

As I fill a hole I add less amendments as I get further out.

As Rick indicated, don't just dig a hole slightly bigger than the pot and drop the tree in. That might work if you have pristine, perfect, non-claybased soil.
