We did just as Bill Cody above suggested and we have had 100% success.
The only thing I have not done is dump them from their tote or pots. I expect them to be root bound this year and will do my best to dump them out.
Used good clay top soil with some fertilizer in a rubber made tote. Planted and placed in shallow water as they grew we moved them deeper and deeper. Now they are placed at 8 feet and come up every year right after the toads are done.
