Starting trees now, or wait?

I just purchased a piece of property in Arkansas. The soil is rock, rock and more rock, with a covering of hard clay.  I have finally finished with a fence as there are many deer.  I have had cow manure hauled in and  had a load of fresh wood chips delivered a week ago to place on top.  I am next focusing on a green house and chicken coup.  While my soil conditions itself over the next year, I was considering raising trees and shrubs in containers and setting  them out next year in the fall of 2022.  Do you think they would survive in a container that long if given extra shelter in a cattle panel greenhouse or should I just wait? Thanks so much.  

If you can't wait, your trees should be fine in pots for a year, so long as the pots aren't too small. You can also buy special pots (root trainers) designed to promote good root architecture and avoid pot binding.
