thanks Bill for the tips,
would letting the lillies colonize for a year be a better timeframe?
I definitely share your concerns, and am pretty tired of feeding nursery stock to various farm animals.
The lilies I am committed to for this year, but I could easily wait on the grass carp until next year.

The clay soil isnt too compacted, we excavated and then lined the pond (due to caliche subsoil). The clay was then just dumped in place with a Bobcat with minimal compaction. So hopefully the lilies can get a good foothold.

To clarify on the planting tech, you are suggesting to not plant the rhizomes in pots? I suppose too that if there are no grass carp, then no need for wire cages at this time? Just stick the rhizomes into the soil, with the tips still emerging, right?

really appreciate your advice-
thanks
