Used milk cartons make the best tree pots:
1) They're free
2) They're tall and skinny, allowing for a deeper tap root
3) To plant, just peel back the carton from the soil and you're good to go!
No cutting is required; just screw on the lid, pop open the top, rinse it out, punch a few holes in the bottom, and add your dirt.
In most cases these just go straight to the landfill so nice to repurpose them and more importantly, avoid using single use plastic pots.
