When I ran out of old plastic tree containers I just screwed together some OSB and made a box and it worked well. Once set up just unscrew and tap the pieces off the concrete. The square shape was nice also for sitting sturdy on the bottom. Maybe check with a nursery and see if they have any used containers you can have.
